    inkCanvas1.SetEnabledGestures(new ApplicationGesture[] 


void inkCanvas1_Gesture(object sender, InkCanvasGestureEventArgs e)
    ReadOnlyCollection<GestureRecognitionResult> gestureResults = 

    // Check the first recognition result for a gesture.
    if (gestureResults[0].RecognitionConfidence == 
        switch (gestureResults[0].ApplicationGesture)
            case ApplicationGesture.Down:
                // Do something.
