Stroke::OnInvalidated Method

Raises the Invalidated event.

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

protected:
virtual void OnInvalidated(
	EventArgs^ e
)

Parameters

e
Type: System::EventArgs
An EventArgs that contains the event data.

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. The InkPresenter handles the Invalidated event and calls the DrawCore method.

The following example draws a Stroke either as a solid stroke or as a series of StylusPoint objects, depending on the Mode property. The example calls the OnInvalidated method, which in turn calls the DrawCore where the stroke is drawn.
