Remarks

The Windows Runtime ItemsControl class creates a new ItemsControlAutomationPeer as its OnCreateAutomationPeer() definition. Derive your automation peer from ItemsControlAutomationPeer if you are deriving a custom class from ItemsControl and want to add automation support for additional features that you enabled in your custom class. Then override OnCreateAutomationPeer() so that it returns your custom peer. Make sure though that there aren't any existing derived classes from ItemsControl that might better suit your scenario. For example, Selector, FlipView, GridView, ComboBox, ListViewBase and ListBox are all a type of ItemsControl. Each of these already has a dedicated automation peer.

Default peer implementation and overrides in ItemsControlAutomationPeer

ItemsControlAutomationPeer has overrides of Core methods such that the associated AutomationPeer methods provide peer-specific information to a Microsoft UI Automation client.

For Windows Phone Store app, ItemsControlAutomationPeer has methods that support creating item-specific automation peers for data items. See CreateItemAutomationPeer(Object) and OnCreateItemAutomationPeer(Object).
