Updatepanel and the disappearing controls

[DasPhansom]

Hi everybody

I wonder that i don't find this bug or problem already. I have an accordion and an Gridpanel in an Updatepanel. In the Accordion I select a value and in a triggered click event I set the DataSource of the Gridpanel. That was the plan. The fact is that when i click at one of the nodes of the treeview inside the accordion every coolite control inside the UpdatePanel disappears!

need Help, thanks.

Ok......

I solved my problem. It seems that it was caused because the Scriptmanager was in the head tag. Very weird problem.

Hope this helps!
