Draw over multiple controls

When a user grabs the border of an object to expand the size or move it I
would like to draw a rectangle to show the growing size or changing position.
The problem is that the MouseDown eevnt is within the active control, while
the line I need to be drawing is outside the control. To make things worse
the line to be drawn may need to "float" over other controls on the page.

If I draw on the canvas of the form the line is behind the visual controls
on top.

Question: How do I draw OVER the top of multiple controls?

Use the System.Windows.Forms.ControlPaint class, which is a utility class
specifically for this sort of thing:
