Updated: December 2011

Namespace:  System.Windows.Automation
Assembly:  UIAutomationClient (in UIAutomationClient.dll)

public static void AddAutomationEventHandler(
	AutomationEvent eventId,
	AutomationElement element,
	TreeScope scope,
	AutomationEventHandler eventHandler
)

Parameters

eventId
Type: System.Windows.Automation.AutomationEvent

The identifier for the event the method will handle.

element
Type: System.Windows.Automation.AutomationElement

The UI Automation element to associate with the event handler.

scope
Type: System.Windows.Automation.TreeScope

The scope of events to be handled; that is, whether they are on the element itself, or on its ancestors and descendants.

eventHandler
Type: System.Windows.Automation.AutomationEventHandler

The method to call when the specified event occurs.

Some classes, such as GridPattern, expose fields identifying events that are specific to the class. The AddAutomationEventHandler method provides a mechanism that enables you to register handlers for these events.

eventHandler can be an instance of the method, or a reference to the method (AddressOf in Visual Basic).
