Format DateTime in Gridview.

Gridview is using mostly , now i have come up with some small but very important task on how to display Proper date time on Gridview , Basically we are defining standard date time option (date + time) , but some time we only want to display date in this case you can follow the below format.Format Date on Bound Column in Grid View

Suppose you want DOB in short date format without time , then you can simply use DataFormatString ="{0:d}" for Short Date
like this

<asp:BoundField DataField="DOB" HeaderText="DOB" DataFormatString = "{0:d}" />

if you are using above this setting then also it will not work ,coz by default the html encode is turned ON to prevent the Cross site Scripting attack , so for that you need to add one more property as HtmlEncode ="false".


<asp:BoundField DataField="DOB" HtmlEnclode="False" HeaderText="DOB" DataFormatString = "{0:d}" />
if You want Logn Date you can use - DataFormatString = "{0:D}"
if You want Logn Time you can use - DataFormatString = "{0:T}"

If you are using Template comlumn and you want to make your date string in short format then also you can use this suppose your item templates is

<ItemTemplate >
<asp:Label ID="DOB" runat="server" Text='<%# Bind("DOB") % >'> </asp:Label >
</ItemTemplate >

Then also you can use like this way:

<asp:Label ID="DOB" runat="server" Text='<%# Bind("DOB","{0:D}") % >'> </asp:Label >

Following table will show some date formating ways in Gridview column.

Format Pattern	Name	Example
d	Short date	11/8/2008
D	Long date	Sunday, August 11, 2008
t	Short time	3:32 PM
T	Long time	3:32:00 PM
f	Full date/time (short time)	Sunday, August 11, 2008 3:32 PM
F	Full date/time (long time)	Sunday, August 11, 2008 3:32:00 PM
g	General date/time (short time)	8/11/2008 3:32 PM
G	General date/time (long time)	8/11/2008 3:32:00 PM

How to know SQL Server version and Edition

some time we just install the sql server , but still we don't know which type of version it is and edition also , basically we need that when we are upgrating current version of new version. Current there is sql server 2008 is there in market,

now how to determine which version of sql 2008 is running out machine,
- run the following T-SQL statement,

SELECT SERVERPROPERTY ('productlevel') ,SERVERPROPERTY('productversion'), SERVERPROPERTY ('edition')

you will get the result like :
RTM | 10.0.1600.22 | Enterprise Edition

RTM is product level which means - 'Release To Manufacturing'.
but what is means of RTM - is a stage on which the distribution of process begins CD of
that product get created and retial packs and then product will get shipp , this is very
long process and because of that RTM date is mostly ahead of the final release date.

10.0.1600.22 means product version.

Enterprise Edition means its a Edition there are some other editions are also there like
Developer,standard ,web,Express ,Workgroup , 64- bit Edition .

The following table lists the Sqlservr.exe version number.

Release	Sqlservr.exe
RTM	2007.100.1600.0
SQL Server 2008 Service Pack 1	2007.100.2531.0

Check for valid Internet Connection using C#

C#
public bool GetIsConnAvail()
{
var success = false;
string StatusMsg;
if (NetworkInterface.GetIsNetworkAvailable() == false)
{
return success;
}
string[] Mysite = { "www.google.com", "www.yahoo.com"};
try
{
using (var ping = new Ping())
{
foreach (var url in Mysite)
{
var replyMsg = ping.Send(url, 300);
if (replyMsg.Status == IPStatus.Success)
{
success = true;
StatusMsg = "Connection Found..."
break;
}
else
{
StatusMsg = "Internet Connection not Found on your machine..."

Check Page.IsValid at Client Side using C#

when i was designing a registration form i run into this case, what i want is if user press register

CSV to XML Conversion using LINQ

on C#, if we want to Convert CSV to XML then you can use Language Integrated Query (LINQ) can be used to convert a CSV file to XML. Here is the sample CSV file that needs to be converted

below example code reads the CSV file to an array. LINQ is used to loop through the array and the contents are written as XML using XElement (System.XML.Linq).


public void ConvCSVToXML()

{

String[] FileContent = File.ReadAllLines(@"D:\Proj\jquery.csv");

String XMLNS = "";

XElement Inv = new XElement("type", from

items in FileContent

let fields = items.Split(',')

select new XElement("fadein",

new XElement("Tab", fields[0]),

new XElement("ProgressBar", fields[1]),

new XElement("ToolTip", fields[2]),

new XElement("Menu", fields[3]),

)
);

File.WriteAllText(@"D:\Proj\jquery.xml", XMLNS + Inv.ToString() );
}


using this you can convert your CSV file xml using C# and C# Convert CSV To XML, .NET CSV To XML

How to get the Upper Bound of an Array in C#

hi, if you'r using asp, vbscript and all then you have option call UBound
which will return a UpperBound value of Array. but on C#, you dont have that option call Ubound ,for that you can use GetUpperBound() option - Gets the upper bound of the specified dimension in the Array.

here is an Example which can show how to use GetUpperBound()


For i = MyArray.GetLowerBound(0) To MyArray.GetUpperBound(0)

Next i


like this way you can use both option call GetLowerBound & GetUpperBound ,
GetLowerBound will return lower bound value.here you have to pass (int value)
0 - 1st arrayvalue, 1- 2ndarrayvalue like that,

thank you.

Download data using FTP or HTTP with C#

If you want to download data via FTP or HTTP then you can use this solution. you can Use the System.Net.WebClient to achieve this. The URI determines whether a file (file://) , FTP (FTP://) or HTTP (HTTP:// or HTTPS://) scheme is to be used.

On .Net2.0 there is an Async Version get added which will allows you download data asynchronously as a background task using its own thread from the thread pool. WebClient object can handle one async download at a time. its not useful for downloading many files concurrently , but if you want to do this then you can use multiple WebClient objects. if you want to Cancel the current download using CancelAsync.

There are Several Methods:

1. OpenRead - returns a System.IO.Stream
OpenReadAsync - async downloading use the handler OpenReadCompleted

2. DownloadData - returns a ByteArray
DownloadDataAsync - use handler DownloadDataCompleted

3. DownloadFile - Saves to a local file
DownloadFileAsync - use handler DownloadFileCompleted

4. DownloadString - returns a String ( introduced in .net 2.0)
DownloadStringAsync - use handler DownloadStringCompleted


Here is Sample code:

using System.IO;
using System.Net;
using System.Text.RegularExpressions;

string remoteUri = "http://www.entersitenamehere.com";
WebClient client = new WebClient();
string str = client.DownloadString(remoteUri);


** if you are using proxy then you need extra code to code around it.
on my next post i will tell you how you can download data using Proxy.
Downloading data over FTP, Downloading data over HTTP, FTP, HTTP, Net.WebClient

SQL : Count String Occurrence

in SQl server, we dont have any function which can return the number of words in a perticular string .but from small tricks we can do that . now Consider here we can separating the character on space basis

example :


declare @Str VARCHAR(2000)
SET @Str = 'Hi this is Test line which count no of spaces.'
select LEN(@Str) - LEN(Replace(@Str,' ', '')) + 1


Above query will return value 10 , but if the words are separate by more than one space then it will aslo count that space. but its wrong as per the answer.
in that case Create one function which can keep multiple spaces as a single space and return proper result

Below is a Function which can remove white space and all and retrun peoper result.

CREATE FUNCTION [dbo].[WordCount] ( @inStr VARCHAR(4000) )
RETURNS INT
AS
BEGIN

DECLARE @Index INT
DECLARE @Char CHAR(1)
DECLARE @PrevChar CHAR(1)
DECLARE @WordCount INT

SET @Index = 1
SET @WordCount = 0

WHILE @Index <= LEN(@InStr)
BEGIN
SET @Char = SUBSTRING(@InStr, @Index, 1)
SET @PrevChar = CASE WHEN @Index = 1 THEN ' '
ELSE SUBSTRING(@InStr, @Index - 1, 1)
END

IF @PrevChar = ' ' AND @Char != ' '
SET @WordCount = @WordCount + 1

SET @Index = @Index + 1
END

RETURN @WordCount
END
GO



now you can use that WordCount Function

DECLARE @String VARCHAR(4000)
SET @String = 'Hi this is Test line which count no of spaces.'
SELECT [dbo].[WordCount] ( @String )


Above Query will return Result 10 not any other,

SQL : how to sort ip Address.

ip address, is one of the key point to identify the user. now if your storing ip address on your database with the VARCHAR datatype with length of 25. guess you have 1 lakh's of records of different ip address and you want to sort that.

Then your sorting query will be

select [ipadd] as IpAddress from ip order by [ipadd]


now in this case it will return a result something like this


ipAddress
------------------------
10.0.0.1
192.165.20.2
255.205.2.3
255.145.53.6
64.35.88.9
68.4.5.99
69.65.236.235
98.125.85.36.0


something like that but actually its not your answer , it get sorted on first no. so becasue of that your result get warry.on actual basic the result should come in this format


ipAddress
------------------------
10.0.0.1
64.35.88.9
68.4.5.99
69.65.236.235
98.125.85.36.0
192.165.20.2
255.205.2.3
255.145.53.6


now how to achieve this use some technique here

select [IPAdd] from ip
order by CAST(PARSENAME([IPAdd], 4) AS INT),
CAST(PARSENAME([IPAdd], 3) AS INT),
CAST(PARSENAME([IPAdd], 2) AS INT),
CAST(PARSENAME([IPAdd], 1) AS INT),


now check this you get above result
thank you.

publish multiple websites using one solution.

on Visual Studio you can publish only one website at a time otherwise there is a clash between one website with multiple website.if you want to do that means on startup of one website other website also publish . for that you need to do some setting on Solutional Level.

follow the steps :
1- on proejct Solution just right click it & select Product Dependencies.
2- select Dependencies tab.
3- select your main website(startup one) from Dropdown.
4- now check all the web service on "Depends on" section
that you can decide how many site you want to publish at a time of this main site.
5- click ok

now whenever you publish that main site , then it will prompt publish window for all other depended site ,then all other mention site will also get publish , if you dont want to publish that you do the same above procedure to deactivated that ,

that's all...

About XmlPreloadedResolver

when using Silverlight then XmlPreloadedResolver meaning is very useful, its a new type which can be useful when your working with XML . on XmlPreloadedResolver it has the Ability to load the DTD without call to network. This type manually maintain the DTD cache and all other with xml streams. XmlPreloadedResolver includes RSS1.0 and XHTML1.0 Defination of DTD.

sample code on how to work with XmlPreloadedResolver


String strDtd = "";
XmlPreloadedResolver resolver = new XmlPreloadedResolver();
resolver.Add(resolver.ResolveUri(null, "nameofDTD.dtd"), strDtd);
XmlReaderSettings rs = new XmlReaderSettings();
rs.XmlResolver = resolver;
rs.DtdProcessing = DtdProcessing.Parse;
XmlReader reader = XmlReader.Create("samplexml.xml", rs);



now you can also set the DTD sets Enable using XmlKnownDtds enumeration.
XmlKnownDtds is used with the XmlPreloadedResolver to identify the well-known DTD

the following example shos preloading Xhtml1.0 DTd into the XmlReaderSettings object
here there is no need of network call to parse the Xhtml file.it will done automatically.


XmlReaderSettings settings = new XmlReaderSettings();
//define the Setting object to parsing DTD
settings.DtdProcessing = DtdProcessing.Parse;
// Define preloading Xhtml10 DTD
settings.XmlResolver = new XmlPreloadedResolver(XmlKnownDtds.Xhtml10);
//suppose read the sample.html file using XmlReader
XmlReader reader = XmlReader.Create("sample.html", settings);
// and load using XDocument object
XDocument document = XDocument.Load(reader);

Some of the Browser used PageXOffset & PageYOffset.

Here is Function call MouseX() and MouseY() which can calculate the X and Y Co-ordinates of same,


function mXbar(action) {
if (action.pageX) return action.pageX;
else if (action.clientX)
return action.clientX + (document.documentElement.scrollLeft ?document.documentElement.scrollLeft :document.body.scrollLeft);
else return null;
}
function mYbar(action) {
if (action.pageY) return action.pageY;
else if (action.clientY)
return action.clientY + (document.documentElement.scrollTop ?document.documentElement.scrollTop :document.body.scrollTop);
else return null;
}



there are few more ways to calculate the cursor position event.ScrenX or event.screenY
these feature are not thee in Netscape4 and IE old version, but in new version of ie 7 + they have all such feature,

Handle Master page Click Event on Content Page

In ASP.net2.5 there a new concept knowns as Master Page , with the help of that you can
customize you'r repeteative work. Create a one Master page and use that page on all the other pages. Its really very good tech to crear your coding and clear your logic also.

now sometime we have a LinkButton define on Master page which can be work as a "Link to the Customer information " and this can be change depend on customer role. and that LinkButton action we want in the Contenet page.

Supoose we have LinkButton call "linkFromMasterPage" on Master Page. Here is small code which can helps you to do same .

C#--

Public LinkButton linkFromMasterPage(){

Get {

Return linkFromMasterPage;

}

}


Now next Process is reference the Master Page as a casted object in the Content page.
here CusMasterPg is a Class of Maste Page.


CusMasterPg cm = ((CusMasterPg) (Master));


Now you can easily access the all the methods, public properties of Master page class.
so next stpe is handle the button Event on your content page


protected void Page_Load(object sender, EventArgs e)
{
If (!(IsNothing(cm))) {

cm.linkFromMasterPage.Click += New EventHandler(linkFromMasterPage_Click);

}
}


next thing is define actual method handle on your page.


Protected void linkFromMasterPage_Click(Object sender, System.EventArgs e){

// write Perform Business Logic Here
}


thats all , you can do same thing for User Controls also for Handle Master page Click Event on Content Page.

Silverlight-based Local Impact Map

It is one of the Great and very Interestig web application devlope by Microsoft ,
there are some reason to devlop this.

The Local Impact Map are conatin around 400+ Stories about the Program of Microsoft around the world.In that you can see it includes the Photos videos and more and more Visual Effects.

It is very interesting and easy to use , i like the one of that feature of Deep Zooming of Map, its really cool and very fast , Its not a ' free mouse-wheelin ' where you can zoom the Preticular location , they are taking advantage of Deep Zooming of image along with zoomo for Controlled Transition.

ASP Format Date and Time

while coding on ASP we required date and time most of the time, how to get this is very basic and well known to the most of the Programmers, but how to get the only specific date , time in required format is a main task ,

for that we have inbuild function call FormatDateTime() .

now we very well knows if we want to get current date and time then we can use now()

<%dim TodayDnT
TodayDnT = now()
%>

if you want the Result of same then use <% Response.write(TodayDnT) %>
so it will return result as : - 8/5/2009 12:11 PM

now we have the option to format that
1. Using 0

<%
Response.write FormatDateTime(TodayDnT,0)
%>

Result : - 8/5/2009 12:11:10 PM

---

2. Using 1

<%
Response.write FormatDateTime(TodayDnT,1)
%>

Result :- Wednesday, August 12, 2009 (long date )

---

3. Using 2

<%
Response.write FormatDateTime(TodayDnT,2)
%>

Result: - 8/5/2009 (short date)

---

4. using 3

<%
Response.write FormatDateTime(TodayDnT,3)
%>

Result : - 12:11:10 PM (long time)

---

5. using 4

<%
Response.write FormatDateTime(TodayDnT,4)
%>

Result : - 11:10 (current time in 24 format (hh:mm)


If you want to change the Date and Time according to international location then
use session.lcid property

Ex : - <% session.lcid=1036 %>
which will set the Date n Time in French Format

here is the List of all the
International Location

Debugging for ASP.NET Applications

If you are using Visual Studio2005 and if you want to enable debugging in the project properties Then Follow the Stpes
In VS 2005, use the <Project> Property Pages to set project properties :
here is the way to do
- Right click on Solution Explore of Project,Then Open the Property Pages by and selecting Property Pages.
- Select Start Option tab
- Under Debuggers, make sure the ASP.NET box is selected.

You can also enable the debugging using web.config file

- Inside the <compilation> tag, you will create the debug attribute.
- specify attribute as a "debug", not "Debug" or "DEBUG" because the are very Case-Sensitive so please take care of that.
- Set debug option as a true.

Here is a sample Web.config file


<configuration>
<system.web>
<compilation defaultLanguage="VB" debug="true" numRecompilesBeforeAppRestart="15">

<compilers>
<compiler language="C#;Csharp" extension=".cs" type="Microsoft.CSharp.CSharpCodeProvider,system, Version=1.0.5000.0, Culture=neutral,

PublicKeyToken=b77a5c561934e089" />
<compiler language="VB;VBScript" extension=".cls" type="Microsoft.VisualBasic.VBCodeProvider,system, Version=1.0.5000.0, Culture=neutral,

PublicKeyToken=b77a5c561934e089" />
</compilers>

<assemblies>
<add assembly="ADODB" />
<add assembly="*" />
</assemblies>

<namespaces>
<add namespace="System.Web.UI" />
<add namespace="System.Web" />
<add namespace="System.Web.UI.WebControls" />
<add namespace="System.Web.UI.HtmlControls" />
</namespaces>
</compilation>
</system.web>
</configuration>


Like that you can set the Debugging option using web.config file also and using GUI also.

Loop through Session ,Application ,form Variable

In Classic asp sometime we need to retrieve all the Session Application and Request object variable, in this case we can use Loop through technique which will generate all the Session variable , application variable , and Request variable are used in current page do this need to simply put this line on your page

1.

<%
dim i
For Each i in Session.Contents
Response.Write(i & "<br />")
Next

dim i
For Each i in Session.StaticObjects
Response.Write(i & "<br />")
Next
%>

it will Display all the Session Contents / session staticobjets are used in current page .


2.

<%
dim i
For Each i in Application.Contents
Response.Write(i & "<br />")
Next
%>


this will iterate all the Application content are being used in current page.

3.

<%
for each x in Request.form
Response.Write("<br>" & x & " = " & Request.form(x))
next
%>


this will generate all the Request variable


4.


<%
for each name in Request.ServerVariables
Response.write ""&name &"-------------"& Request.ServerVariables(name) &"<br>"
Next
%>

it will loop with the all the Server Variable.

Export XML from SQL using a Stored Procedure.

1) Generate a file with the text-editor like:


<%begindetail%>
<%insert_data_here%>
<%enddetail%>


Save it as c:\temp\template.tpl

2) Open Query Analyzer and type:


sp_makewebtask @outputfile = 'c:\temp\myxmlfile.xml',
@query = 'select * from sysobjects for xml auto',
@templatefile = 'c:\temp\template.tpl'

The result is a XML-File!

Eliminate Duplicate records from the Grid View

Most of the time we need to delete duplicate entries from GridView, in this case we can delete it manually also or using onRowcreate also we can remove that .

Example
suppose Mr.Xyz has has more than 2 Account in Blogspot.com site and we want to show
in GridView Person and RelatedBlogs like this





and in this case we dont want to repeat Person name on each row.
- I have a data source

DataTable dtsource = new DataTable();

//Adding columns to datatable
dtsource.Columns.Add("Person");
dtsource.Columns.Add("Related Blog");

//Adding records to the datatable
dtsource.Rows.Add("kiran", "kirank.blog.com");
dtsource.Rows.Add("kiran", "webdevlopmenthelp");
dtsource.Rows.Add("kiran", "www.kiran.com");
dtsource.Rows.Add("mark", "mark.blog.com");
dtsource.Rows.Add("mark", "asp-net.blogspot.com");


put the below code in codebehind


private void GenerateUniqueData(int cellno)
{
//Logic for unique names

//Step 1:

string initialnamevalue = grdUniqueNames.Rows[0].Cells[cellno].Text;

//Step 2:

for (int i = 1; i < grdUniqueNames.Rows.Count; i++)
{

if (grdUniqueNames.Rows[i].Cells[cellno].Text == initialnamevalue)
grdUniqueNames.Rows[i].Cells[cellno].Text = string.Empty;
else
initialnamevalue = grdUniqueNames.Rows[i].Cells[cellno].Text;
}
}



on GridView define property OnRowCreated="GenerateUniqueData" it will search the record via cell and set the Person name as a empty or person name

Caching in ASP.NET

Caching

is one of the best technique of persisting the data in memory for immediate access to requesting program calls.Caching is about storing data in memory the first time it is requested and then re-using it for the following requests for a specified period of time.

Why Caching is important ?

Every time we have to querying database for each request is not cost-effective in terms of server resources, hence is lot better to cache or persist the data to avoid this costly loss of resources.so in this case we are imporve the system performance and avoid the consistancy.

ASP.Net Provides the flexibility in terms of caching at different levels.

• Fragment Caching


in this case caching a user control that can be used in a base web form page.if you have used include files in the traditional ASP model then this caching model is like caching these include files separately. In ASP.NET more often this is done through User Controls. Initially even though one feels a bit misleading, this is a significant technique that can be used especially when implementing "n" instances of the controls in various *.aspx pages. We can use the same syntax that we declared for the page level caching as shown above, but the power of fragment caching comes from the attribute "VaryByControl". Using this attribute one can cache a user control based on the properties exposed.

Syntax: <%@ OutputCache Duration="60" VaryByControl="DepartmentId" %>

The above syntax when declared within an *.ascx file ensures that the control is cached for 60 seconds and the number of representations of cached control is dependant on the property "DepartmentId" declared in the control.

Add the following into an *.ascx file. Please note the use of tag "Control" and the cache declaration.

<script runat="server">
private int _Departmentid=0;
public int DepartMentId
{
get{return _Departmentid;}
set{_Departmentid =value;}
}
//Load event of control
void Page_Load(Object sender, EventArgs e)
{
lblText.Text = "Time is " + DateTime.Now.ToString() + " for Department id = "
+ _Departmentid + "\n";
}
</script>
<asp:Label id="lblText" runat="server"></asp:Label>




Add the following to an *.aspx file. Please note the way "Register" tag is used;
the declaration of control using syntax <[TagPrefix]:[TagName]>



<%@ Page Language="C#" Trace="true" %>
<%@ Register TagPrefix="CacheSample" TagName="Text" Src="CachingControl.ascx" %>
<script runat=server>
void Page_Load(Object sender, EventArgs e)
{
this.lbltime.Text ="Base form time is " + DateTime.Now.ToString() + "\n";
}
</script>
<html><head><title></title><body>
<asp:Label id="lbltime" runat="server"></asp:Label>
<CACHESAMPLE:TEXT id="instance1" runat="Server" DepartMentId="0">
</CACHESAMPLE:TEXT>
<CACHESAMPLE:TEXT id="instance2" runat="Server" DepartMentId="1">
</CACHESAMPLE:TEXT>
</body>
</html>


• Application Level Caching


With Page level Output caching one cannot cache objects between pages within an application. Fragment caching is great in that sense but has limitations by using user controls as means to do. We can use the Cache object programmatically to take advantage of caching objects and share the same between pages. Further the availability of different overloaded methods gives a greater flexibility for our Cache policy like Timespan, Absolute expiration etc. But one of the biggest takes is the CacheDependancy. This means that one can create a cache and associate with it a dependency that is either another cache key or a file.

Find below the snippet that uses CacheDependancy. Here what I have done is to provide a list view of existing employees. You need to create a Database in Sql Server, setup some data before you can continue. The schema scripts are enclosed in the article.

Add database connection value in Web.Config and change the value as per your setup.


<appSettings>
<add key="conn" value="Data Source=vishnu;trusted_connection=yes;Initial Catalog=Users"/>
</appSettings>


First I get the dataset into which I fill the user list. But before this I check for the cache initially if it exists I directly cast it to a dataset, if not create a cache again.
daUsers.Fill(dsUsers,"tblUsers");


• Page Level Output Caching

This is at the page level and one of the easiest means for caching pages. This requires one to specify Duration of cache and Attribute of caching.

Syntax: <%@ OutputCache Duration="60" VaryByParam="none" %>

The above syntax specifies that the page be cached for duration of 60 seconds and the value "none" for VaryByParam* attribute makes sure that there is a single cached page available for this duration specified.

so at last Caching is a technique that definitely improves the performance of web applications if one is careful to have a balance in terms of which data needs to be cached and parameter values for expiration policy.

hope this article helps you to imporve your applicaiton performance and best result ever

IsPostBack property

IsPostBack-Gets a value indicating whether the page is being loaded in response to a client postback, or if it is being loaded and accessed for the first time.

when the page is loaded in order to determine whether the page is being rendered for the first time or is responding to a postback. If the page is being rendered for the first time, the code calls the Page..::.Validate method.

Syntax:


private void Page_Load()
{
if (!IsPostBack)
{
// Validate initially to force asterisks
// to appear before the first roundtrip.
Validate();
}
}


Example


protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
PageDataBind();
}
else
{
Response.write("2nd Time Visisted..");
}
}

protected void PageDataBind(string SearchProduct)
{
SqlDataAdapter SDA ;
DataSet ds = new DataSet();
String sql = "select * from Emp where ID ='"+ DropDownList.SelectedItem.Text +"'";
SDA.Fill(ds, "productDetails");
ShowId.DataSource = ds;
ShowId.DataBind();
}


when loading of the page, the control doesn't go through the redundant action of re-loading the control. It loads it only once, at the initial page load. Once the page is loaded, the click event from the button (or however you post back) is considered to be a postback. Yes, the page gets reloaded, but, by surrounding your data population with this statement, the page knows that the initial data loading was already done, so it doesn't happen any more, and it gets maintained throughout any subsequent post back. The second, and most rewarding thing that happens is that the selection which was made by the end user is maintained throughout the post back. This is the pay-off - by doing it with the If/Then Page.IsPostBack statement, your selection carries through to your query and the query returns the results you wanted in the first place.

Filter User via IP

its a good technique to Restrict user to view your website , this task can be done with the help of checking of user's IP Address and match with our database and if user get found under
that IP then you can set Denied Access to them .

But in this case you need a Live IP Address database,
there are so many website are there they are provides free IP Address database range .

and with the help of that u can Denied user.

here are the List of free IP address database sites

• http://www.ipinfodb.com/ip_database.php


• http://www.ip-db.com/

Simply download that.

1. Create one IP check function
2. take user Ip address

in ASP : - Ip =Request.Servervariables("REMOTE_HOST")
in C# : - String ipAddress = (Request.ServerVariables["REMOTE_ADDR"]);

3. then check if user's Ip address is there in you'r database , depend on that
you can prevent user.


hope it will helps you,

open new window in GridView using OnRowCreated

In GridView using "OnRowCreated" function we can add onClick function.

here is the sample code

html code


<asp:TemplateField HeaderText="Header 3">
<ItemTemplate>
<asp:Label ID="Label1" runat="server" Text="Click Me"></asp:Label>
</ItemTemplate>
</asp:TemplateField>


and CodeBehind is


protected void Gridview1_RowCreated(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
Label l = (Label)e.Row.FindControl("Label1");
if (l != null)
{
string script = "window.open('Default.aspx');";
l.Attributes.Add("onclick", script);
}
}
}


run the Application and click "Click Me" it will open new window , indirectly we are adding
OnClick Event in That Row.

CountDown Timer

Hi , here is cool triks of CountDown timer, mostly its useful in website while validating time like online exam, date time , game countdown , and so many

Below is the code needed to display count down in HTML page using javascript.

You define container for the count down (either <span> or <div> tag) and the initial value, and the code updates the time automaticlly in the format HH:MM:SS

You can also control the style of the container using standard CSS, as demonstrated in the below and attached code.

To activate the count down in one of your existing pages you
have to follow two steps:

1. include the attached CountDown.js file with:


<script type="text/javascript" src="CountDown.js"> <script>


2. have such javascript in the section:



<script type="text/javascript">
window.onload=WindowLoad;
function WindowLoad(event) {
ActivateCountDown("CountDownPanel", 100);
}
</script>


where "CountDownPanel" is the ID of the container
(i.e. you should have <span> or <div> with this ID) and 100 is the time in seconds to be counted.

here is CountDown.js file -------------------------------

var _countDowncontainer=0;
var _currentSeconds=0;

function ActivateCountDown(strContainerID, initialValue) {
_countDowncontainer = document.getElementById(strContainerID);

if (!_countDowncontainer) {
alert("count down error: container does not exist: "+strContainerID+
"\nmake sure html element with this ID exists");
return;
}

SetCountdownText(initialValue);
window.setTimeout("CountDownTick()", 1000);
}

function CountDownTick() {
if (_currentSeconds <= 0) {
alert("your time has expired!");
return;
}

SetCountdownText(_currentSeconds-1);
window.setTimeout("CountDownTick()", 1000);
}

function SetCountdownText(seconds) {
//store:
_currentSeconds = seconds;

//get minutes:
var minutes=parseInt(seconds/60);

//shrink:
seconds = (seconds%60);

//get hours:
var hours=parseInt(minutes/60);

//shrink:
minutes = (minutes%60);

//build text:
var strText = AddZero(hours) + ":" + AddZero(minutes) + ":" + AddZero(seconds);

//apply:
_countDowncontainer.innerHTML = strText;
}

function AddZero(num) {
return ((num >= 0)&&(num < 10))?"0"+num:num+"";
}



Twitter API in C#

I used C# and WCF, but I could have just as easily used an ASMX web service. This code is fairly simple.

Note: This code will not run as listed. You have to have a password. This code has that as a shared variable, but I'm not showing that to you, seriously. I hope that this is of some help to you.



[OperationContract]
public void SubmitUserStatus(string username, string tweet)
{
// encode the username/password
string user = Convert.ToBase64String(System.Text.Encoding.UTF8.GetBytes(username + ":" + password));
// determine what we want to upload as a status
byte[] bytes = System.Text.Encoding.ASCII.GetBytes("status=" + tweet);
// connect with the update page
HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://twitter.com/statuses/update.xml");
// set the method to POST
request.Method = "POST";
// thanks to argodev for this recent change!
request.ServicePoint.Expect100Continue = false;
// set the authorisation levels
request.Headers.Add("Authorization", "Basic " + user);
request.ContentType = "application/x-www-form-urlencoded";
// set the length of the content
request.ContentLength = bytes.Length;
// set up the stream
Stream reqStream = request.GetRequestStream();
// write to the stream
reqStream.Write(bytes, 0, bytes.Length);
// close the stream
reqStream.Close();
}

Pass multiple parameter using HyperLink field in GridView

While using Hyperlink field u can send multiple parameter in Gridview , and then u can retrive it using QueryString Parameter.

here in this Example when user will click on username then it will redirect to
http://xyz.com/ShowUser.aspx?id={0}&city={1} this page
and it will pass customer id and city .






<asp:SqlDataSource id="datasource1" runat="server" SelectCommand="SELECT CustomerID, CompanyName, City FROM Customers"
/>

<asp:GridView id="gridview1" DataSourceID="datasource1" runat="server"
AutoGenerateColumns="False">
<Columns>

<asp:BoundField DataField="CustomerID" HeaderText="BoundField" />

<asp:HyperLinkField
DataTextField="CustomerName"
DataNavigateUrlFields="CustomerID,City"
DataNavigateUrlFormatString=
"http://xyz.com/ShowUser.aspx?id={0}&city={1}" />

</Columns>
</asp:GridView>



Detecting Client IP address

To keep track of Visitor's Record such as IP address and all
then u can use this way ,
it will display the Client proxy ip address , if the client is using Proxy server.



if (Context.Request.ServerVariables["HTTP_VIA"] != null)
{
IP = Context.Request.ServerVariables["HTTP_X_FORWARDED_FOR"].ToString();
}
else
{
IP = Context.Request.ServerVariables["REMOTE_ADDR"].ToString();
}



Paging with DataList Control

DataList is a data bound list control that displays items using certain templates defined at the design time.The content of the DataList control is manipulated by using templates sections such as FooterTemplate, HeaderTemplate, ItemTemplate, SelectedItemTemplate ,AlternatingItemTemplate, EditItemTemplate and SeparatorTemplate

PagedDataSource, is a class that encapsulates the paging related properties for data-bound controls such as DataGrid, GridView, DataList, DetailsView.

Now lets take an Example of Displaying Country on Datalist with Paging

Steps.

1. Create Datalist for Country

<asp:DataList ID="dlCountry" runat="server">
<ItemTemplate>
<asp:Label ID="Label1" runat="server" Text='<%# Eval("Country_Code") %>'></asp:Label>
<asp:Label ID="Label2" runat="server" Text='<%# Eval("Country_Name") %>'></asp:Label>

2. now on Code Behind write a method to fetch data from the Country’s table.

private void BindGrid()
{
string sql = "Select * from Country Order By Country_Name";
SqlDataAdapter da = new SqlDataAdapter(sql, “Yourconnectionstring”);
DataTable dt = new DataTable();
da.Fill(dt);

pds.DataSource = dt.DefaultView;
pds.AllowPaging = true;
pds.PageSize = Convert.ToInt16(ddlPageSize.SelectedValue);
pds.CurrentPageIndex = CurrentPage;
lnkbtnNext.Enabled = !pds.IsLastPage;
lnkbtnPrevious.Enabled = !pds.IsFirstPage;

dlCountry.DataSource = pds;
dlCountry.DataBind();

doPaging();
}



3.Call this BindGrid method in the Page load event.

protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
BindGrid();
}
}


4.Declare a PagedDataSource object at page scope.
PagedDataSource pds = new PagedDataSource();

5. create new property call CurrentPage to maintain the latest selected page index.
and pu this code on it.

public int CurrentPage
{

get
{
if (this.ViewState["CurrentPage"] == null)
return 0;
else
return Convert.ToInt16(this.ViewState["CurrentPage"].ToString());
}

set
{
this.ViewState["CurrentPage"] = value;
}

}


6.write a method ‘doPaging’ to create a list of page numbers.

private void doPaging()
{
DataTable dt = new DataTable();
dt.Columns.Add("PageIndex");
dt.Columns.Add("PageText");
for (int i = 0; i < pds.PageCount; i++)
{
DataRow dr = dt.NewRow();
dr[0] = i;
dr[1] = i + 1;
dt.Rows.Add(dr);
}

dlPaging.DataSource = dt;
dlPaging.DataBind();
}


7. create new paging event


protected void dlPaging_ItemCommand(object source, DataListCommandEventArgs e)
{
if (e.CommandName.Equals("lnkbtnPaging"))
{
CurrentPage = Convert.ToInt16(e.CommandArgument.ToString());
BindGrid();
}
}


8. Previous And Next Button Events


protected void lnkbtnPrevious_Click(object sender, EventArgs e)
{
CurrentPage -= 1;
BindGrid();
}

protected void lnkbtnNext_Click(object sender, EventArgs e)
{
CurrentPage += 1;
BindGrid();
}


9.Change PageSize Dynamically

protected void ddlPageSize_SelectedIndexChanged(object sender, EventArgs e)
{
CurrentPage = 0;
BindGrid();
}



10.HighLight Selected Page Number


protected void dlPaging_ItemDataBound(object sender, DataListItemEventArgs e)
{
LinkButton lnkbtnPage = (LinkButton)e.Item.FindControl("lnkbtnPaging");
if (lnkbtnPage.CommandArgument.ToString() == CurrentPage.ToString())
{
lnkbtnPage.Enabled = false;
lnkbtnPage.Font.Bold = true;
}
}
