The documentation is quite clear, it lists the events that are supported:
ListCollectionView Class (System.Windows.Data) | Microsoft Learn[
^].
In your case, you want to listen to the
CollectionChanged[
^] event.
UPDATE
Here is how to handle the
CollectionChanged
event:
private void OnCollectionChanged(
object? sender,
NotifyCollectionChangedEventArgs e)
{
if (e.NewItems?.Count > 0)
{
}
if (e.OldItems?.Count > 0)
{
}
}
