Draw over grid

[h]

Hi,
I have a user control "internalPanel" containing databoundgrid, and I put this user control in another one "externalPanel". When user drag a pointer of ruler in ExternalPanel I will draw a line over the internalPanel. But I can''t draw over this cusercontrol, it draw under this control. How can I draw over this control ???
Thank you very much

If you replace our grid with a Windows Forms DataGrid, do you see the same problem. The reason to try this is to see if you need to work through our grid to try to solve this problem or if it is something about how the drawing happens outside of our grid that is causing this behavior.

Is this some kind of ''rubberband'' line that has one endpoint fixed, and the other endpoint moves as you drag the mouse?

If you can post a sample project showing this problem and what you are trying to do, then maybe we can suggest something.
