I'm using the TabbedMDIManager and I want to have a "Close All" menu option in my Window menu - I've tried several methods to close all windows, starting with closing each Form in the rootForm.MdiChildren collection but this causes a null pointer exception.
If I was using a normal MDI form I would get rootForm.OwnedForms - but this collection is empty. Could you advise or point to an example to do this?
I'll also be adding a "Close All But This" - which leaves the active child form.
