Ispostback:

 

if (!this.IsPostBack)

{

   Session["Reset"] = true;

 

   Configuration config = WebConfigurationManager.OpenWebConfiguration("~/Web.Config");

 

   SessionStateSection section =      (SessionStateSection)config.GetSection("system.web/sessionState");

 

     int timeout = (int)section.Timeout.TotalMinutes * 1000 * 60;

      function DisplaySessionTimeout(timeout) {

            var seconds = timeout / 1000;

            document.getElementsByName("seconds").innerHTML = seconds;

            setInterval(function () {

                  seconds--;

                  document.getElementById("seconds").innerHTML = seconds;

            }, 1000);

            setTimeout(function () {

                     //Show Popup before 20 seconds of timeout.

                     $("#ExpireConfirm_Submit").dialog({

                              height: 200,

                              width: 400,

                              resizable: false,

                              modal: true,

                              title: "Session Expire Confirmation",

                              open: function () {

                                          $('p#id1').html(sessionTimeout);

                              },

                              buttons: {

                                       "Yes": function () {

                                                $(location).attr("href", "/Account/Logout").submit();

                                                $(this).dialog("close");

                                          },

                                       "No": function () {

                                                ResetSession();

                                                $(this).dialog("close");

                                           }

                                       }

                                 }).prev(".ui-dialog-titlebar").css("background", "red");

                           }, timeout - 20* 1000);

                           setTimeout(function () {

                                    $(location).attr("href", "/Account/Logout").submit();

                           }, timeout);

                  };

                  function ResetSession() {
