virtual void OnMeasureItem(System::Windows::Forms::MeasureItemEventArgs ^ e);
protected virtual void OnMeasureItem (System.Windows.Forms.MeasureItemEventArgs e);
abstract member OnMeasureItem : System.Windows.Forms.MeasureItemEventArgs -> unit

Protected Overridable Sub OnMeasureItem (e As MeasureItemEventArgs)
A MeasureItemEventArgs that contains the event data.
Raising an event invokes the event handler through a delegate. For more information, see Handling and Raising Events.
The OnMeasureItem method also enables derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.
When overriding OnMeasureItem(MeasureItemEventArgs) in a derived class, be sure to call the base class's OnMeasureItem(MeasureItemEventArgs) method so that registered delegates receive the event.
