|IsCurrentBeforeFirst||Gets a value that indicates whether the CurrentItem of the view is beyond the start of the collection.|
|IsEmpty||Gets a value that indicates whether the view is empty.|
|SortDescriptions||Gets a collection of SortDescription instances that describe how the items in the collection are sorted in the view.|
|SourceCollection||Gets the underlying collection.|
