WeakEventManager.StartListening Method

When overridden in a derived class, starts listening for the event being managed. After the StartListening method is first called, the manager should be in the state of calling DeliverEvent or DeliverEventToList whenever the relevant event from the provided source is handled.

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

protected abstract void StartListening(
	Object source
)

Parameters

source
Type: System.Object

The source to begin listening on.

Notes to Inheritors

StartListening overrides should add a handler to the provided source. The handler is declared by the manager itself. The class handler should not be public, and it should only be called in response to the event being managed. The class handler should call the DeliverEvent method or the DeliverEventToList method appropriately.
