Remarks
Notes to Inheritors
ItemAutomationPeer derives from FrameworkElementAutomationPeer and overrides several FrameworkElementAutomationPeer APIs. Generally the overrides follow a pattern where if the ItemAutomationPeer has a nonnull Owner, then the implementation calls base. If the owner is null, then the implementations check for an associated container and use its automation information if possible. The fallback values if neither of these conditions are true are generally the value defaults for that data type, or otherwise representat that there is not a conventional UI item associated with this item in the automation tree.
