aspx_professional thread: Forcing a page to restore its Viewstate


Message #1 by "David Beaumier" <david.beaumier@s...> on Fri, 13 Dec 2002 16:14:08
Hi everyone,

I need to keep the state of a page and be able to restore it when the user 
navigate back to this page. So far, I overloaded the 
LoadPageStateFromPersistenceMedium and SavePageStateToPersistenceMedium to 
persist the page state within the user's Session. 

Unfortunately, when the user navigate back to the page, the 
LoadPageStateFromPersistenceMedium method is not called by the framework 
(it seems to be called only when the page is loaded after a postback). I 
did not found a way to force the page to reload its Viewstate. A method 
named LoadPageViewState() exists in the System.Web.UI.Page class but it is 
a friend method... so I cannot call it directly from my code.

Does anyone have a clue on how I can persist and restore the page state? 
Does the version 1.1 of ASP.NET will allow us to force a reload of the 
state by calling the LoadPageViewState() method?

Thanks,

David
