Property Value

The number of records in the view or -1 if the number of records is unknown.

If a filter is set, this property value only includes items that pass the filter. If the underlying collection is of type IEnumerable, this is an O(N) operation. This value is cached until the collection changes.

When deriving from CollectionView, override this property to provide a more efficient implementation.
