I have a problem a few days ago that I cannot solve:
I have a modals popups extender from asp.net that when pressed on a button opens another popup (if something changes, both are users controls only).
The problem arises at the close of the second. I am currently using:
modalpopup.Dispose ()
When you do this, the modal pop up leaves, causing the first to stop responding.
If you need, I can attach some part of the code that can guide you. Thank you!
