MobilePage.OnViewStateExpire Method

Handles an exception caused by an expired view state on postback. This API is obsolete. For information about how to develop ASP.NET mobile applications, see the Web site.

Namespace:  System.Web.UI.MobileControls
Assembly:  System.Web.Mobile (in System.Web.Mobile.dll)

protected virtual void OnViewStateExpire(
	EventArgs e


Type: System.EventArgs
An object defined by an EventArgs object that contains event data.


The session state has expired.


The session cookie from the client is invalid.


The session state history has exceeded its allocated size.

If you expect to restore a page from a view state, and the page's underlying session has expired, this method's default implementation raises an exception. You can override this method, perform custom handling to restore the page state without relying on view state, and return without calling the base implementation.
