CurrentChangingEventManager CurrentChangingEventManager CurrentChangingEventManager CurrentChangingEventManager Class

Definition

Provides a WeakEventManager implementation so that you can use the "weak event listener" pattern to attach listeners for the CurrentChanging event.

public ref class CurrentChangingEventManager : System::Windows::WeakEventManager
public class CurrentChangingEventManager : System.Windows.WeakEventManager
type CurrentChangingEventManager = class
    inherit WeakEventManager
Public Class CurrentChangingEventManager
Inherits WeakEventManager
Inheritance
CurrentChangingEventManagerCurrentChangingEventManagerCurrentChangingEventManagerCurrentChangingEventManager

Remarks

In order to be listeners in this pattern, your listener objects must implement IWeakEventListener. You do not need to implement IWeakEventListener on the class that is the source of the events.
