I\'ve got a WPF app using the Model-View-ViewModel pattern.
In my ViewModel I\'ve got a ListCollectionView to keep a list of items.
This ListCollectionView is bound

For me the best answer is to break a little the principle of MVVM.

On the code behind 1. Instanciate your viewModel 2. add an event handler SelectionChanged 3. iterate through your selected items and add each item to your list of the viewModel

ViewModel viewModel = new ViewModel();

viewModel.SelectedModules = new ObservableCollection();

foreach (var selectedModule in listBox1.SelectedItems)
{
    viewModel.SelectedModules.Add(selectedModule.ToString());
}
