// Add this code to the contstructor or OnLoaded method. if (inkCanvas1.IsGestureRecognizerAvailable) { inkCanvas1.EditingMode = InkCanvasEditingMode.InkAndGesture; inkCanvas1.Gesture += new InkCanvasGestureEventHandler(inkCanvas1_Gesture); inkCanvas1.SetEnabledGestures(new ApplicationGesture[] {ApplicationGesture.Down, ApplicationGesture.ArrowDown, ApplicationGesture.Circle}); } ... void inkCanvas1_Gesture(object sender, InkCanvasGestureEventArgs e) { ReadOnlyCollection<GestureRecognitionResult> gestureResults = e.GetGestureRecognitionResults(); // Check the first recognition result for a gesture. if (gestureResults[0].RecognitionConfidence == RecognitionConfidence.Strong) { switch (gestureResults[0].ApplicationGesture) { case ApplicationGesture.Down: // Do something. break; case ApplicationGesture.ArrowDown: // Do something. break; case ApplicationGesture.Circle: // Do something. break; } } }
