beforeunload, stop user from switching tabs
posted

I have a page that has a  webtab control with 2 tabs. On the unload  I have a prompt to alert the users that they have data unsaved when unload is called.

 jQuery(window).bind('beforeunload', function(e) {
      
        return "Unsaved data."
       
       
         });

If you switch tabs and  click on stay on this page the tab index still changes and the new tab does not load. Is there a way to restore the tabs to the original state before unload was called?

    Hi dan2012a,

    I suggest that you handle the SelectedIndexChanging client-side event and cancel it if the user choose certain option:

            function SelectedIndexChangingdHandler(sender, eventArgs) {

                var a = confirm("Unsaved data! Continue?");

                if (!a) {

                    eventArgs.set_cancel(true);

                }

    Please let me know if this helps.
