WPF: How do I hook into a ListView's ItemsSource CollectionChanged notification?

Question

I have a ListView that is databound to an ObservableCollection ...

Answer 1

you are going to have to attach the handler to your list. Or, use a CollectionView and hook the changed event there.

in your codebehind, do like this:

MyList.CollectionChanged += new NotifyCollectionChangedEventHandler( this.MyCollectionChanged );


private void SortCollectionChanged( object sender, NotifyCollectionChangedEventArgs e )
{
  Debug.WriteLine( "Changed" );
}
