Private Methods

Method	Description
OnIsEnabledChanged ( object sender, System.Windows.DependencyPropertyChangedEventArgs e ) : void	Handle changes to the control's IsEnabled property.
OnIsReadOnlyChanged ( bool value ) : void
OnLoaded ( object sender, RoutedEventArgs e ) : void	Handle the control's Loaded event.
UpdateVisualState ( bool useTransitions ) : void	Update the visual state of the control. UpdateVisualState works differently than the rest of the injected functionality. Most of the other events are overridden by the calling class which calls Allow, does what it wants, and then calls Base. UpdateVisualState is the opposite because a number of the methods in InteractionHelper need to trigger it in the calling class. We do this using the IUpdateVisualState internal interface.
