Dear All,
My question is do I need to store values of a combo box in the viewstate
so that between postbacks of the page the values in the combo box are retained
(I think I need not save the values in the view state if I have set the
EnableViewState property of the combo box to true but I'm not sure as don't
know how to test this between postbacks).

Next question is when does a post back actually happen on the page.

Thanks in Advance.

Many Regards
