WPF toolkit CheckListBox SelectedItemsOverride not working

Question

I have a check list box from the wpf toolkit 2. I cannot get all of the selected items. I read that I am supposed to use SelectedItemsOverride to get all of my selected items bu

Answer 1

I combined previous answers/comments and what worked for me was to bind SelectedItemsOverride to an ObservableCollection, include UpdateSourceTrigger=PropertyChanged, and attach a method to the ObservableCollection's event CollectionChanged.

The XAML:

Code in ViewModel:

public IEnumerable AllItems { get; set; }

public ObservableCollection SelectedItems { get; set; }

public ViewModel()
{
    SelectedItems = new ObservableCollection();

    SelectedItems.CollectionChanged += SelectedItems_CollectionChanged;
}

private void SelectedItems_CollectionChanged(object sender, System.Collections.Specialized.NotifyCollectionChangedEventArgs e)
{
    // Handle collection changed event
}
