If EventsSource is not nullNothingnullptra null reference (Nothing in Visual Basic), then EventsSource is reported as part of the event.

Handling an automation event including its specific automation event arguments is not enabled within the Windows Phone core API. Handling the event requires that the handler be part of a UI Automation client, and the infrastructure for implementing a UI Automation client is tied to the UIAutomationClient.dll assembly that is part of Microsoft Windows rather than being a part of the Windows Phone core. Raising an automation event from the set that is identified by AutomationEvents does not require you to package event data; any required event data is provided by the UI Automation infrastructure when it reports the event to UI Automation clients.
