I currently have a page that contains a RadTreeView. On each node of the RadTreeView is an ASP.NET Ajax CollapsiblePanelExtender. In the code-behind I have certain panels expanded and certain panels collapsed based on some business logic. Is there a way to detect when ALL ASP.NET-generated Javascript (collapsing/expanding of CollapsiblePanelExtender) has run? I need to act on the elements but NOT until all expanding and collapsing has taken place.

The CollapsiblePanelExtender initializes by using Sys.Application.init Event. If you used the Sys.Application.load Event, you could guarantee your code ran after theirs.

Thanks so much! I've been trying to find a solution for quite some time and this was the only one that worked! – Brian David Berman Jan 12 '10 at 19:51
