You need to override a couple of methods.

VB Code:

Protected Overrides Sub SavePageStateToPersistenceMedium(ByVal viewState As Object)
 
 
 
    End Sub
 
    Protected Overrides Function LoadPageStateFromPersistenceMedium() As Object
        Return Nothing
 
    End Function
 
    Protected Overrides Function SaveViewState() As Object
 
        Return Nothing
 
    End Function
