Hi,

In my Web user control, I have AnimationExtender inside a UpdatePanel. It works OK when I load page for first time. but after I perform an action, it stops working and throw following error.

Error

'Sys.InvalidOperationException: Two componenets with the same id 'TestAnimationExtender' can't be added to the application.

 Any Help?

Thanks

Hi,

I got the same error message trying to make a tabbed panel into an update panel.

It seems like no AJAX control can be placed in update panel.

I think the reason is the content in update panel (your AnimationExtender, my tabbed panel) does not get disposed on client side between each updates. This might cause a web-page that might be partially updated many times taking a lot of memory. I hope I'm wrong, though.

I'm looking for a way to solve this problem, too.
