Vlad,

You are right in that the GridHitTest is not really needed in these circumstances. It's just that this framework gives more control (and leaves room for expansion) as to the where of the mouse event. It allows to use different popups depending on where the mouse is + mouse button used

eg :
I use the box in upper left corner to show a popup which allows the users to hide/show and reorder the columns of the grid. The recordmarker popup is used to do things related to that specific record, etc
