Remarks

If the insertion of new items is to be handled manually, a new item must be provided and the Handled property set to true to indicate that the process will be handled manually. If a new item is provided but the Handled property was not set or was set to false, the item will be ignored and a new item will be created by the DataGridCollectionView (if possible). An InvalidOperationException will be thrown if the Handled property is set to true but a new item is not provided.

If a new item is not provided and the event is not handled, an attempt will be made by the DataGridCollectionView to create a new item.
