Data Binding with WPF and MVVM/Model-View-ViewModel

I'm having difficulty correctly Data Binding my models in the view. I have a MainWindowViewModel which contains a list of AlbumViewModels. Each AlbumViewModel holds an AlbumModel. So I have multiple albums and I need to display information in an ObservableCollection in the AlbumModel. I have two ListBoxes. ListBox1 holds the list of AlbumViewModels that are in my MainWindowViewModel. My second ListBox I want to display the ObservableCollection from the current selected item from the AlbumViewModel.AlbumModel. How can I do this? I've tried binding the DataContext of ListBox2 to the ListBox1 element, along with SelectedItem as the path but that returns 'AlbumViewModel'. Is there anyway to bind ItemsSource of a ListBox to the binding of the DataContext, but in thi开发者_StackOverflow中文版s case binding it to [DataContext].AlbumModel.ObservableCollection or something?

I apologise if it sounds rather complicated!

You can use the fact, that when you bind to a collection, WPF wraps collection to CollectionView. And this guy has CurrentItem.. Bea had good article: How can I sync selection of two data bound ListBoxes? and Dr.WPF is amazing (as usual): ItemsControl: 'C' is for Collection.
