Asp.net set session timeout

Asp.net set session timeout:

By default our websites session timeout is 20 mins after that session will gets expire suppose if we want to set our custom timeout in our applications we can set it in different ways 


Write below code in .CS file
  string str_jscript = "TimeOutExpire(" + Convert.ToString(Session.Timeout * (60 * 1000)) + ");";
        Page page = System.Web.HttpContext.Current.Handler as Page;
        System.Web.UI.ScriptManager.RegisterStartupScript(page, page.GetType(), "", str_jscript, true);



Write Below code  in .ASPX page

 <script type="text/javascript">
        var timer;
        function TimeOutExpire(obj) {
            window.clearTimeout(timer);
            timer = window.setTimeout(function () { window.location = "Loginpage.aspx?PID=EAN" }, parseInt(obj));
        }          
    </script>
