To store the view state on the server, use the following code sample:

C#:

protected override object LoadPageStateFromPersistenceMedium() { 
   return Session["_ViewState"]; 
}

protected override void SavePageStateToPersistenceMedium(object viewState)
{ 
       Session["_ViewState"] = viewState; 
}


VB.NET

Protected Overrides Function LoadPageStateFromPersistenceMedium() As Object
        Return Session("_ViewState")
End Function

Protected Overrides Sub SavePageStateToPersistenceMedium(ByVal viewState As Object)
        Session("_ViewState") = viewState
End Sub
