I have a form. It has a panel docked to the top and a panel docked to the bottom. The remainder of the form is a panel in the middle. I want it to expand to fill the remainder of my form so I set the dockstyle to FILL for this center panel. When I do this visually nothing jumps around but my resizing adorners move upward/downward behind my top and bottom docked panels. Now my resize adorners are the same size as the base form.
What am I doing wrong? My middle panel acts like it does not understand there is a boundary that is established by the top and bottom docked panels on the form. It just extends right past where I believe it should stop.

Try clicking on the middle panel that is getting overlapped by the other panels to select it, then right-click it and select
Bring To Frontfrom the context menu to fix the issue.
