In your C# code:

public Visibility AdministratorVisibility
{
    get 
    { 
        MyPrincipal.CurrentPrincipal.IsInRole("Administrator") ? Visibility.Hidden : Visibility.Visible; 
    }
}

You can do the same thing for implementing something for IsReadOnly. If the user's role can change (I'm not sure how these user roles work), you can implement INotifyPropertyChanged and do NotifyPropertyChanged("AdministratorVisibility"), otherwise you could probably change the BindingMode to BindingMode.OneTime and skip implementing the notifications.

This probably isn't a whole lot better than what you're doing already, but it's probably as good as you're going to get.
