Sorry for the bump but this is by far the best example I could Google find. I have got the menu working when I applied it in XAML as per your example.
So now, how do I apply it to a RadGrid that is created at runtime using C#?
The following is saying "Cannot Resolve symbol IsEnabled":
VerticalAlignment = VerticalAlignment.Top,
RowIndicatorVisibility = Visibility.Collapsed,
Thickness(10, 74, 0, 0)
Help appreciated, thanks.
