I have a borderless form that I'm "docking" onto the top edge of my screen. Inside of the form, I'm placing a single toolstrip control, which docks across the entire form (picture the taskbar to get an idea of what I'm talking about). Because the borderless form has no edge to it, I wanted to draw a black line along the bottom edge of the form to differentiate the form from the windows or desktop behind it.
The problem that I'm facing is that the toolstrip will not move "behind" the line when it's docked, no matter how I order the control layers. I've tried programatically sending the control to back to no avail either.
Any ideas on how to get the line to show above the docked toolstrip? Thanks in advance.
