Exception

[Jarod]

I got following expeption:
Always when I try to update gridView using detailsView on the SECOND time.
So I made 1 update, and I try to make another one and than boom... I don't
add any controls dynamically its' pretty simple detailsView. But gridView
and detailsView are in View control is it a problem ? I don't make anything
with it. On the whole page I don't add anything dynamically all what's done
in my code is setting Visisble / true / false in detailsView and than I
dataBind() on gridView. So why do I get exception ?

Failed to load viewstate. The control tree into which viewstate is being
loaded must match the control tree that was used to save viewstate during
the previous request. For example, when adding controls dynamically, the
controls added during a post-back must match the type and position of the
controls added during the initial request.
Description: An unhandled exception occurred during the execution of the
current web request. Please review the stack trace for more information
about the error and where it originated in the code.
