Raises the MeasureItem event.
[Visual Basic] Protected Overridable Sub OnMeasureItem( _ ByVal e As MeasureItemEventArgs _ ) [C#] protected virtual void OnMeasureItem( MeasureItemEventArgs e ); [C++] protected: virtual void OnMeasureItem( MeasureItemEventArgs* e ); [JScript] protected function OnMeasureItem( e : MeasureItemEventArgs );
- A MeasureItemEventArgs that contains the event data.
Raising an event invokes the event handler through a delegate. For more information, see Raising an Event.
The OnMeasureItem 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 OnMeasureItem in a derived class, be sure to call the base class's OnMeasureItem method so that registered delegates receive the event.
