How to redirect to the login page automatically when session timeout in C#

 On my last project my client ask me to do some thing so can after certain of time if the website page is in idle mode for a specified time(session timeout) then the current user should automatically redirect to the login page! very interesting. i took this a a challenge and thanks god i able to do this.

Here i am showing  how to redirect to the login page automatically when session timeout in C#

Write this code in to the masterpage's cs file

 protected override void OnPreRender(EventArgs e)
            this.HeadContent.Controls.Add(new LiteralControl(
                String.Format("<meta http-equiv='refresh' content='{0};url={1}'>",
                SessionTimeOutWithin * 60, PageToSentAfterSessionTimeOut)));
This will add a metatag into the page header which will refresh the CheckSessionTimeOut.aspx page after SessionTimeOutWithin* 60 seconds when the session timeout occurs.

//This the page to be refresh after sessioin timeout
public string PageToSentAfterSessionTimeOut
            get { return "CheckSessionTimeOut.aspx"; }

//This takes the Session.Timeout from the webconfig or from where the Session.Timeout is being set
 public int SessionTimeOutWithin
            get { return Session.Timeout; }

// Add this within the <system.web> tag in web.config file . Here i am set 1 min as Session timeout

    <sessionState mode="InProc" cookieless="true" timeout="1"></sessionState>

 This will set the session timeout as 1 minute

Mode: means what happens if page is in active mode , InProc means session timeout will increase 1 minute more after the page activity time but if the page is in idle for 1 minute then session timeout will occurs.

How to split values in sql server?

 Here i am showing how to split values in Sql server as Split function did  in c#

Why should we take some string value from a table and split that on our C# programming why not in the SQL programming? so many times we prefer to save a One to Many relation type with a single field in a SQL db table by concatenating the selected item with a separator like"1,4,8,7". But as we know SQL don't have a function like C# has Split(). So many programmer takes that value from db and split it in the C# code. But i am not happy with that as always going for better option and i implement this Function for that and thanks god its works..

Create function [dbo].[fnSplit](
    @sInputList VARCHAR(8000) -- List of delimited items
  , @sDelimiter VARCHAR(8000) = ',' -- delimiter that separates items
) RETURNS @List TABLE (item VARCHAR(8000))

WHILE CHARINDEX(@sDelimiter,@sInputList,0) <> 0

 IF LEN(@sItem) > 0

IF LEN(@sInputList) > 0
 INSERT INTO @List SELECT @sInputList -- Put the last item in
--select * from dbo.fnSplit('1,2,34,5', ',') where item=34
--select * from dbo.fnSplit('1,2,34,5', ',')

Hope this will helps you tooooo :)
