Mouse Click event information

[Wraith2]

I'm using a WinForms PieChart and I want to be able to detect a right click on any data point and show a context menu with possible actions. I can't work out how to get a mouse event that tells me what mouse button was used. The DataPointerDown, ChartPointPointerDown and VisualElementsPointerDown either don't contain any information about the click itself or are limited to the location of the event. The standard inherited Click and MouseClick events do not fire.

Is this possible? If so, how? And if it is not can it be added please?
