Firefox Update panel after 2 mins idle time

Recently, I fight with firefox bug which aborting my partial postback from update panel after 2 mins idle time.

Here was my step to investigate this problem

• check other browsers (IE, IE6, Chrome) – and the result, only firefox does this weird behaviour
• create simple update panel and tested on FF. – unfortunately this work perfectly
  and then I wonder why my actual code does not work.
• Apply more content on Update Panel – It is not work again (oh my be it’s I need to make my content on update panel smaller)
• After trying to make my update panel content smaller, it still not work.
• Then I use my previous simple update panel to test if it is content outside update panel is matter. – (Yes, it is the content outside update panel is matter)
• Confuse how I solve this, we still need to use update panel for particular reason because of the due date, etc. so we can’t change anything (we have to keep the update panel but has to work in FF)

After looking around the solutions, luckily I found on the other section of my project work perfectly after 2 mins idle in FF.

I try to investigate why that section work but not this. Finally I figure out that the different is that part is calling ajax call on other page before call partial postback.

Then here is my simple solutions to fix this.

• Register Begin Request
  Sys.WebForms.PageRequestManager.getInstance().add_beginRequest(microsoftAJAX_BeginRequest);
• check the browser if it is mozilla and the time difference is 2 mins then request to other server page (ASPX page) first synchonously before continue the process.
  
  Here is the code, hopefully it will help your problem as well.
  

  //check availability for partial postback for FF fixed. FF will abort the partial postback call after 2 mins unless it call ajax to other page first
   var checkConnectionForPartialPostback = function ()
   {
       $.ajax({
           url: "/usercontrols/testconnection.aspx",
           async: false
       });
   };
  
   //check availability for partial postback for FF fixed. FF will abort the partial postback call after 2 mins unless it call ajax to other page first
   var checkAvailabilityForPartialPostback = function ()
   {
       //firefox fix for time diff        
       if ($.browser.mozilla && GetTimeDiff(new Date(), lastLoadTime).getMinutes() >= 2)
       {
           //refresh this page            
           checkConnectionForPartialPostback();
       }
       else
       {
           lastLoadTime = new Date();
       }
   };
