PropertyChangedEventHandler Delegate

Definition

Represents the method that will handle the PropertyChanged event raised when a property is changed on a component.

public delegate void PropertyChangedEventHandler(System::Object ^ sender, PropertyChangedEventArgs ^ e);
public delegate void PropertyChangedEventHandler(object sender, PropertyChangedEventArgs e);
public delegate void PropertyChangedEventHandler(object? sender, PropertyChangedEventArgs e);
type PropertyChangedEventHandler = delegate of obj * PropertyChangedEventArgs -> unit
Public Delegate Sub PropertyChangedEventHandler(sender As Object, e As PropertyChangedEventArgs)

Parameters

sender
Object

The source of the event.

e
PropertyChangedEventArgs

A PropertyChangedEventArgs that contains the event data.

Remarks

When you create a PropertyChangedEventHandler delegate, you identify the method that will handle the event. To associate the event with your event handler, add an instance of the delegate to the event. The event-handler method is called whenever the event occurs, unless you remove the delegate. For more information about event-handler delegates, see Handling and Raising Events.

Extension Methods
