This class wraps a Selector control and implements the ISelectionAdapter interface. A selection adapter is a part required by the AutoCompleteBox control template. The SelectorSelectionAdapter provides custom behavior for the AutoCompleteBox control, such as an item collection, selection members, and key handling.

You can create a new template for the AutoCompleteBox and provide your own ISelectionAdapter to provide custom selection functionality without deriving from the AutoCompleteBox class.
