>Is there a way I can detect a DblCkick in a grid, I mean execute the grid's DblClick not the cell's control DblClick where the user pressed the DblClick?

Well the grid does have a DblClick method, but what if the user Double-Clicks the column-header or control? Do you want the Grid Double-Click to fire as well? You would have to code the DblClick methods of the column controls and headers to call the Grid DblClick method.
