In addition to the insertion events, the DataGridCollectionView and DataGridCollectionViewSource classes also expose the RemovingItem and ItemRemoved events, which are raised when the Remove or RemoveAt methods have been called to signal that an item is about to be removed or has been removed, respectively, from the underlying data source.

If the process is manually handled, the Handled property received in the event parameters of the RemovingItem event must be set to true. The removal process can also be canceled by setting the Cancel property to true.
