From what I see there, the mouse, while moving over the rows, can go over different controls in the container(s). Then all those controls should have some code in MouseMove() event of their respective classes.
The preferrable way to do it is to bind the MouseMove() event of those controls with a delegate method and have all MouseMove() handling code in one place.
