I would like to inherit from the Infragistics controls (2008, Web, for framework 3.5) and utilize the inherited ViewState collections.  Does documentation exist anywhere as to what names (e.g. a regex) are guaranteed not to collide with parent usage of the ViewState.  I.e. I don't want to write to ViewState("somekey") and have it overwrite something used by the Infragistics control and cause weird behavior.

Thanks
