RoutedEventArgs.OnSetSource(Object) Method

Definition

Namespace:

System.Windows

Assembly:

PresentationCore.dll

When overridden in a derived class, provides a notification callback entry point whenever the value of the Source property of an instance changes.

protected:
 virtual void OnSetSource(System::Object ^ source);

protected virtual void OnSetSource (object source);

abstract member OnSetSource : obj -> unit
override this.OnSetSource : obj -> unit

Protected Overridable Sub OnSetSource (source As Object)

Parameters

source

Object

The new value that Source is being set to.

Notes to Inheritors

Changing the reported source of an event programmatically can potentially require updating the type-specific data within the event. For this reason, the OnSetSource(Object) method is protected virtual and is intended to be overridden by subclasses of RoutedEventArgs.

This method has no default implementation.
