Yes that idea looks true, but...

When every thing is correct you can use the mouse.x and mouse.y position.
For the column, grid or table view you have row height and column widths
Some calculation with this you can find the cell coordinates where the click 
did happen and take the need actions.
I did this in the past on a grid view to find the cell (row/column)

The only thing that was not possible was if the first visible row was not the
first row of the real rows.
i.e. scrolled in 100 rows and the first visible row is row number 25.

I did ask in the past for a property to be able to get the first visible row
in the grid. (VB does have this property)
