When overridden in a derived class, raises the System.WinForms.UpDownBase.Changed event.
[Visual Basic] MustOverride Protected Sub OnChanged( _ ByVal source As Object, _ ByVal e As EventArgs _ ) [C#] protected abstract void OnChanged( object source, EventArgs e ); [C++] protected: virtual void OnChanged( Object* source, EventArgs* e ) = 0; [JScript] protected abstract function OnChanged( source : Object, e : EventArgs );
Raising an event invokes the event-handling method through a delegate. For an overview, see [DelegateTopicTBD].
Notes to Inheritors: When overriding OnChanged in a derived class, be sure to call the base class's OnChanged method.
