Here's the scenario:

I've got a control (DataGrid) that I want to display my popup menu when I right click in a cell. So I have a "mouseup" routine that looks for a right click.

Problem is that the control, as part of its native functionality, also reacts to the right click event to display the standard edit popup menu.

My question is how to I pre-emp the native popup with my own?

subclassing...?
