I'm working in Excel but the same should apply for all products where you can define custom add-in commands. When you create a custom add-in command in the ribbon, you are able to toggle it from enabled to disabled and back again using Office.Ribbon.RequestUpdate(). You cannot do the same when you define a command for the context menu. I need to be able to toggle the availability or enabled state of my add-in command(s) in the context menu. The function we want to use a command for doesn't make sense to add as a button in the ribbon.
