Currently there is no way to do that by using binding. Instead, you can make a List<> and add the values from the enumeration in the list. Then you can use this list as data source.
C#
List<Dock> enumDataSource = new List<Dock>() { Dock.Left, Dock.Top, Dock.Right, Dock.Bottom };
this.lbDock.ItemsSource = enumDataSource;
where lbDock is of type ListBox.
That's it!
