Silverlight3 bind checkbox list to a datagrid

Question

I have a enum, like public enum TestType { Red = 1, Blue = 2, Green = 3,
Black = 4 } I want to attach those values to a datagrid as checkboxes in silverlight 3. (I would like to bind to a listview, but its not exists in silverlight)

Manage to get the enums to a ObservableCollection, any help to bind to datagrid? I tried with ItemsSource="{Binding Path=nameOfTheObservableCollection, }"
