Here's my delimma. I have a 3rd party control resize event that I want to suppress when the container panel is resizing. A form conveniently has a resizebegin and resizeend event. With that I can set a flag to on in the begin and off in the end event. In the controls resize event I can suppress functionality when the flag is on. A panel does not expose a resizing or resized event. Any ideas on how I could do this? PS This can't fire off the forms resiing events and the form may have 2 or more panels with splitbars and the resizing of the splitbar may cause the panels to resize.
