    inkCanvas1.EditingMode = InkCanvasEditingMode.InkAndGesture;
    inkCanvas1.Gesture += new InkCanvasGestureEventHandler(inkCanvas1_Gesture);
    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. 
            case ApplicationGesture.ArrowDown:
                // Do something. 
            case ApplicationGesture.Circle:
