I have copied the controls and decorations from one content page to another, as they are almost similar.
But the following problems are happening:
(1) Button events are not firing.
(2) One page is loaded multiple times.
(3) Some AJAX buttons are not visible.
Can any one tell me why is this happening?

If you’re using Visual Studio, it’s possible that the controls were not registered w/the .designer.cs file. Check to make sure they’re all there.
