  I've got a situation with a site where cancelling (rather preventing) a post-back, adds the input blocker even though the post-back never actually occurs.
  
  here is the code which is called for the   initPartialRequest()  event:
  
  

  confirmPostBack = function (sender, args){

      var confirmed = confirm("you might loose data, continue?");

      if (! confirmed){

          console.log("PREVENT POST BACK!!!");

          alert("Cancel called!!");

          var prm = Sys.WebForms.PageRequestManager.getInstance();

          if (prm.get_isInAsyncPostBack()) {

              alert("IS ASYNC POST-BACK");   

              prm.abortPostBack();

          }else{

              alert("NOT ASYNC POST-BACK !?!");  

              args.set_cancel(true);

          }

      }

  }

  
  We are only using the basic update panels and activated the DNN async refresh for this module.   the page itself uses the telerik RadTabStrip and has a few RadGrids within the various tabs of the page.
  
  The above code seems to work, since the page is not updated if we press cancel, but just after the confirm dialog closes, the page blocker appears, which is strange imho.
  
   help... I admit I am pretty lost at where to look for a solution... everything I search seems to indicate that I'm doing things properly.  There is also very little stuff on the net for these advanced asp.net event handling issues.

  Hi Max,
  
  I have pasted a demo link that demonstrates Ajax / Partial Ajaxification. You could see if this will be in any help. If your problem still persists, please elaborate further on your scenario and, particularly, let us know from what control and when is the below JavaScript function called and what is its relation with the RadControls?
