RoutedEventArgs.OnSetSource(Object) Method
Definition
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
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.
