I noticed when you disable a RibbonBarButton only its Text property gets affected. It grays out the corresponding text and that's it. You can still hover the button (image) itself, so it looks like the button has not been disabled at all. It would be great that a disabled RibbonBarButton shows a grayed out Text and Image without hover effect, like it is used within Office software. I don't know if there's a workaround for this or if it's a known issue which will be corrected in an upcoming release. Hopefully someone can clear things up for me. Thanks in advance.
