Remarks

When a collection view implements the IEditableCollectionView interface, you can directly change the underlying collection, if it allows changes to be made, by using the methods and properties that IEditableCollectionView exposes, regardless of the collection's type.

The PagedCollectionView type implements IEditableCollectionView, so you can edit a collection that uses that type.
