IncrementalStrokeHitTester.StrokeHit Event

Occurs when the IncrementalStrokeHitTester intersects an ink Stroke.

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

public event StrokeHitEventHandler StrokeHit
/** @event */
public void add_StrokeHit (StrokeHitEventHandler value)

/** @event */
public void remove_StrokeHit (StrokeHitEventHandler value)

In JScript, you can handle the events defined by a class, but you cannot define your own.
You cannot use this event in XAML.

The following example demonstrates how to dynamically erase a portion of a Stroke. To create a control that allows a user to erase ink, see How to: Erase Ink on a Custom Control.

// When the stylus intersects a stroke, erase that part of
// the stroke.  When the stylus dissects a stoke, the 
// Stroke.Erase method returns a StrokeCollection that contains
// the two new strokes.
void eraseTester_StrokeHit(object sender,
    StrokeHitEventArgs args)
    StrokeCollection eraseResult =
    StrokeCollection strokesToReplace = new StrokeCollection();
    // Replace the old stroke with the new one.
    if (eraseResult.Count > 0)
        presenter.Strokes.Replace(strokesToReplace, eraseResult);
