public partial class ajaxtimer : System.Web.UI.Page

Hope this will sort ur problem...

cretae a warning.aspx page and put ur warning message and Ok button there..
and create a global js file and place the below code inside it.

JavaScript

   function Timeout()
   {
       //have hardcoded the session timeout below..u can get it from code behind
       window.setTimeout(DisplayWarning,90000-12000)//this will display warning after 13 min from page load
   }
   function DisplayWarning()
   {
      //display ur warning here
       var  newwindow =window.open( "warning.aspx", "WarningTitle",  "channelmode=0,toolbar=0,location=0,directories=0,status=0,menubar=0,scrollbars=0,resizable=0,width=330,height=220", true);
       newwindow.focus();
Timeout();
   }

Import this js on every page..and call Timeout() function on onload like ..<body onload="Timeout();">...here u can think of a better solution like calling the timeout function from one common place ..ex.having some parent class

In warning.aspx page add below code

JavaScript

function CloseWindow()
{
   var bclicked = "<%=bclicked%>";
    if(bclicked ==  "True" || bclicked ==  "true" )
    {
        window.close();
    }
}

Call this CloseWindow() function on onload like <body onload="CloseWindow();">

and In code behind the code shud be..

C#

public bool bclicked = false;
protected void Page_Load(object sender, EventArgs e)
{
    bclicked = false;
}
protected void Button1_Click(object sender, EventArgs e)
{
    bclicked = true;
}

What you can do is have the session count down timer displaying in a label on the page, then crate a base page that you inherit your pages from.
Using the basepage you set the Page_PreInit event, then inject the timeout via javascript when the page is loaded. So when the page is postback, the session resets and the counter starts over. the session time you can set in you config file, so you can increase your session time if required at a later stage.

Here is a basic session counter that will update the label on the master page displaying the time left (lblSessionTime) and trigger the log off button on the master page (ctl00_lbtnLogOff) when the session expires.

C#

protected void Page_PreInit(object sender, EventArgs e)
        {         
            if (!this.Page.ClientScript.IsStartupScriptRegistered(this.GetType(), "SessionTime"))
            {
                this.Page.ClientScript.RegisterStartupScript(this.GetType(),
                    "SessionTime", "var sessionTimeout = "
                    + Session.Timeout.ToString()
                    + "; function DisplaySessionTimeout() { document.getElementById('"
                    + this.Master.FindControl("lblSessionTime").ClientID
                    + @"').innerText = sessionTimeout; sessionTimeout = sessionTimeout - 1; if (sessionTimeout >= 0) window.setTimeout(""DisplaySessionTimeout()"", 60000); else {alert(""Your current Session is over.""); document.getElementById(""ctl00_lbtnLogOff"").click();}}", 
                    true);
            }
            this.Page.ClientScript.RegisterStartupScript(this.GetType(), "onLoad", "DisplaySessionTimeout();", true);
           
        }

alert user when session time out
