Hello, Actipro People!
I know that the Floating value was removed from the DockingWindowState enumeration recently, thus I can't hook to the floating state change anymore. What I ended up doing is casting the DockSite.FloatingDockHosts collection to an INotifyCollectionChanged and hooking onto its CollectionChanged event. This way I can check for the "Add" (basically a new floating window) and "Remove" (going back to docked state) actions and do my work on the DockHosts that I want.
Though my question is: is there a cleaner way to hook onto the proverbial float event of a window?
