Get ViewState of all the Controls in the Page

[Sunil Menon]

Dear All,
I would like to access the ViewState Object of all the controls in
the page. When I use the ControlsCollection and access the ViewState
Object of a Control, I get an error message "You cannot access a
protected property"
How do I access the ViewState Object of all the controls in my page?

Thanks & Regards
Sunil
