No Ideas ?

Hello Falk,

Please mind the following:
1) You should never call Rebind/DataBind in the NeedDataSource handler
2) You should never call DataBind when using advanced data-binding.
3) You don't have to call DataBind on each postback when using simple data-binding

I recommend that you examine the following links:
Simple Data-binding
Advanced Data-binding

Let me know if the problem still persists.
