With regards to the RadContextMenu documentation it states:
"You can attach RadContextMenu to any UI element on your page. All you have to do is create your object, put a RadContextMenu inside its closing tags and define the event that will open the context menu".
I tried this with the RadCalendar, and VS complained stating:The RadCalendar does not support direct Content.
Sorry Iam am new to XAML, so a bit confused. Isn't the RadCalendar a UI element?
