One update panel updated and other one is also updated?

Question

I have scenario, I have two update panels on the page (both have update mode='conditional'). If I update one update panel the other is automatically updated. This is first problem.

I am using UpdatePanelAnimationExtender. If one update panel is updated, that don’t have updatepanelAnimationExtender other one also updated and that have updatepanelAnimationExtender, OnUpdatingUpdatePanel(); event is fired. As the documentation of updatepanelAnimationExtender says: http://www.asp.net/AJAX/AjaxControlToolkit/Samples/UpdatePanelAnimation/UpdatePanelAnimation.aspx

OnUpdating - Generic animation played as when any UpdatePanel begins updating

OnUpdated - Generic animation played after the UpdatePanel has finished updating (but only if the UpdatePanel was changed)

Problem: OnUpdating fired and it worked backend and not finished because onUpdated only fired when an UpdatePanel Changed

Answer 1

"Add 2 update panel on page, set updatemode='conditional' for both and add load event for both updatepanel and set breakpoint for both load event and add 1 button and then add Asyn trigger for button click on 1 update panel.... you will notice when you hit button, it should load only triggered update panel and 2nd one remain unchanged, but 2nd updatepanel is load event also fired"

This will happen only if the button is inside the 2'nd updatepanel? If not, then I dont think it will update the second update panel. Could you confirm if the button is inside or outside the second updatepanel?
