How to detect pen button press and release events

Is there any way to detect when user presses or releases button on the pen within APP?

Either the top button, or "right click" button on surface pen

Alternatively, how to detect, that the button is pressed when pen touches InkCanvas.

enter image description here

If you want the InkCanvas.InkPresenter.UnprocessedInput.PointerPressed to work you got to set the InkCanvas.InkPresenter.InputProcessingConfiguration.Mode to InkInputProcessingMode.None but with that done your InkCanvas wont draw or erase any strokes anymore until you progrramed your own draw/erase method.

You may subscribe to PointerPressed event on InkCanvas. It has args PointerRoutedEventArgs e. Filter your input device and separate buttons like this:

if (e.Pointer.PointerDeviceType == Windows.Devices.Input.PointerDeviceType.Pen)
{
    var point = e.GetCurrentPoint(YourCanvasName);
    if (point.Properties.IsLeftButtonPressed)
    {
        //Button1
    }
    if (point.Properties.IsMiddleButtonPressed)
    {
        //Button2
    }
    if (point.Properties.IsRightButtonPressed)
    {
        //Button3
    }
}

Should work though i don't have a pen to test :)
