Clearing viewstate for dynamic user controls

[Perecli Manole]

I have a form that dynamicaly loads user controls based on user
postbacks. Everything works well except that the framework seems to
want to match the viewstate data from my previous control to the new
control on post back even through the IDs are all different. Is
there a way to selectively clear the viewstate of a control before
the framework does the match and applies the viewstate? Disabling
the viewstate is not an option since I need it when the dynamic
control is not swapped.

Thanks
