How can I save asp:HiddenField value across postback?

Answer 1

Set EnableViewState to True

Answer 2

If you are dynamically adding it that will happen if its added too late in the page life cycle. Add it in PreInit and you should be fine. Check out http://msdn.microsoft.com/en-us/library/ms178472.aspx for more info.
