EventManager Class

Provides event-related utility methods that register routed events for class owners and add class handlers.


Namespace:  System.Windows
Assembly:  PresentationCore (in PresentationCore.dll)

Public NotInheritable Class EventManager

The EventManager type exposes the following members.

Public methodStatic memberGetRoutedEventsReturns identifiers for routed events that have been registered to the event system.
Public methodStatic memberGetRoutedEventsForOwnerFinds all routed event identifiers for events that are registered with the provided owner type.
Public methodStatic memberRegisterClassHandler(Type, RoutedEvent, Delegate)Registers a class handler for a particular routed event.
Public methodStatic memberRegisterClassHandler(Type, RoutedEvent, Delegate, Boolean) Registers a class handler for a particular routed event, with the option to handle events where event data is already marked handled.
Public methodStatic memberRegisterRoutedEventRegisters a new routed event with the Windows Presentation Foundation (WPF) event system.

This class is most commonly used to register a new routed event, with RegisterRoutedEvent.

The second most common API usage is RegisterClassHandler. You use this method to enable class handling of a routed event on the class, or an attached event. For details, see Marking Routed Events as Handled, and Class Handling.

The following example show how to use this class to register a new routed event as a class member, along with the routed event "wrapper" technique of overriding the add and remove implementations for a CLR event.

		Public Shared ReadOnly ButtonColorChangedEvent As RoutedEvent = EventManager.RegisterRoutedEvent("ButtonColorChanged",RoutingStrategy.Bubble,GetType(DependencyPropertyChangedEventHandler),GetType(Shirt))

		Public Custom Event ButtonColorChanged As RoutedEventHandler
			AddHandler(ByVal value As RoutedEventHandler)
			End AddHandler
			RemoveHandler(ByVal value As RoutedEventHandler)
				MyBase.RemoveHandler(ButtonColorChangedEvent, value)
			End RemoveHandler
			RaiseEvent(ByVal sender As Object, ByVal e As RoutedEventArgs)
			End RaiseEvent
		End Event
