I have a couple of FormattedTextEditor controls and in design mode I have selected all for the ContextMenuItems However, items such as select font, bold italic etc are not shown in the drop down. Is there something else you have to do?
I think I've seen this before, but it's a timing thing with Visual Studio. Make sure that, after you select the various ContextMenuItems, you click somewhere else in the property grid to make sure that Visual Studio serializes the changes made. Also make sure that the 'Default' checkbox is no longer checked.
