According to this page: https://docs.telerik.com/devtools/winforms/controls/menus/contextmenu/context-menus
I should be able to assign a radcontextmenu to the contextmenu of the radsyntaxeditor. However, I'm finding that not to be the case as you can see below. my contextmenu named ctxMenuEditor is of type radContextMenu.
The below screenshots should show the problem I think. Basically, for whatever reason, the radsyntaxeditor doesn't accept the radcontextmenu, just contextmenu object type.
