Stroke::Invalidated Event

Occurs when the appearance of the Stroke changes.

Namespace:  System.Windows.Ink
Assembly:  PresentationCore (in PresentationCore.dll)

public:
 event EventHandler^ Invalidated {
	void add (EventHandler^ value);
	void remove (EventHandler^ value);
}

The InkPresenter handles the Invalidated event and calls the DrawCore method. If you inherit from the Stroke class and your stroke's appearance is based on a custom state, you must call the OnInvalidated method to raise the Invalidated event.
