You using uncompiled .Net right?
Try to rebind on the event, may be the ViewState is not been hold

Thanks Herique, i don't understand what u mean by uncompiled.net. i try
rebind on the event but it seems the same

Uncompiled ASP.NET is when you dont use the compiler to generate a .dll
with the aspx.cs(vb) files.

You tryed to put a Response.Write on the event to see if the problem is
not with the event it self?
