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
)
You cannot use methods in XAML.

Parameters

source
Type: System.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 method is protected virtual and is intended to be overridden by subclasses of RoutedEventArgs.

This method has no default implementation.
