RoutedEventArgs.OnSetSource Method (Object)

 
System_CAPS_noteNote

The .NET API Reference documentation has a new home. Visit the .NET API Browser on docs.microsoft.com to see the new experience.

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)

abstract OnSetSource : 
        source:Object -> unit
override OnSetSource : 
        source:Object -> unit

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.
