Remarks
SelectingItemsControl provides a base class for ItemsControls that maintain a selection (single or multiple). By default only its SelectedIndex and SelectedItem properties are visible; the current multiple Selection and SelectedItems together with the SelectionMode properties are protected, however a derived class can expose these if it wishes to support multiple selection.
SelectingItemsControl maintains a selection respecting the current SelectionMode but it does not react to user input; this must be handled in a derived class. It does, however, respond to IsSelectedChangedEvent events from items and updates the selection accordingly.
