OnBackgroundChanged Method
Summary
Raises the BackgroundChanged event.
Syntax
protected virtual void OnBackgroundChanged(RoutedPropertyChangedEventArgs<Brush> e)
Protected Overridable Sub OnBackgroundChanged( _ByVal e As RoutedPropertyChangedEventArgs(Of Brush) _)
protected:virtual void OnBackgroundChanged(RoutedPropertyChangedEventArgs<Brush^>^ e)
Parameters
e
A RoutedPropertyChangedEventArgs that contains the event data.
Remarks
Raising an event invokes the event handler through a delegate.
The OnBackgroundChanged method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.
Notes to Inheritors: When overriding OnBackgroundChanged in a derived class, be sure to call the base class's OnBackgroundChanged method so that registered delegates receive the event.
