Remarks

IXRSelector is an intermediate base class for both the IXRComboBox control and the IXRListBox control. It enables the combo box or list box to handle information about item selections. An item can be selected because of user interaction, or because a related property value changed. You can attach a delegate to the selector object that can handle the event that is raised when the selected item changes. To do this, call IXRTextBox::AddSelectionChangedEventHandler.

IXRSelector is an items control and inherits from IXRItemsControl. You can retrieve its content as an item collection, by calling its inherited method IXRItemsControl::GetItems. The IXRItemCollection collection object that is retrieved from GetItems stores the selectable items that are displayed in the list.
