What you need to do is to make sure that your controls are recreated before
page state is restored - that gives you an option of using the PreInit, Init,
InitComplete event handlers together, in your case, with overriding the
CreatingControlHierarchy method in myDataGrid. I attached your sample updated
with the above changes.
