I am trying to use ModalPopupExtender as way to disallow the user from interacting with the site while a DB activity is completed.
I have a different requirement from what is specified in the ASP.NET sample for the AJAX Toolkit control..
This is what i want to do..
Show() the modalpopup
do the DB stuff asynchronously with BeginInvoke by pass the a method that hides modalpopup
I cant get this to work even after 4/5 hours of effort..
Logically i dont see why this shouldnt work...
Can someone give me some advice and provide some code samples
