Disable ViewState on base class only?

[Damien]

Is it possible to somehow disable the ViewState on the base object but
leave the ViewState on within the new object? For example, I have a
server control which inherits from DataGrid. I would like to disable
the DataGrid ViewState while keeping ViewState enabled for my custom
code (e.g. Properties). I've tried base.EnableViewState = false and it
seems to turn everything off.

Thanks in advance for your help!
