Gets a value that indicates whether the CurrentItem of the view is before the beginning of the collection.

Views allow the same data collection to be viewed in different ways, depending on sorting, filtering, or grouping. Views also provide a current record pointer concept and enable moving the pointer. This example shows how to get the current object as well as navigate through the objects in a data collection using the functionality provided in the CollectionView class.
In this example, myCollectionView is a CollectionView object that is a view over a bound collection.
In the following example, OnButton is an event handler for the Previous and Next buttons in an application, which are buttons that allow the user to navigate the data collection. Note that the and IsCurrentAfterLast properties report whether the current record pointer has come to the beginning and the end of the list respectively so that MoveCurrentToFirst and MoveCurrentToLast can be called as appropriately.
The CurrentItem property of the view is cast as an Order to return the current order item in the collection.
