RoutedEventArgs.OnSetSource Method

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

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

protected virtual void OnSetSource (
	Object source
protected void OnSetSource (
	Object source
protected function OnSetSource (

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 method is protected virtual and is intended to be overridden by subclasses of RoutedEventArgs. This method has no default implementation.
