Automation Patterns

This automation peer implements the following pattern interfaces: IExpandCollapseProvider, IGridProvider, IScrollItemProvider, ISelectionProvider.

Notes to Inheritors

The FrameworkElementAutomationPeer overrides in DataGridGroupItemAutomationPeer follow a pattern of returning results based on a row header group owner if one exists, and otherwise returning defaults such as String.Empty or null.
