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

A DrawItemEventArgs that contains the event data.
Remarks
This method is called each time an owner-drawn ComboBox item needs to be drawn and after OnMeasureItem is called. For more information, see DrawItem.
Raising an event invokes the event handler through a delegate. For more information, see Handling and Raising Events.
The OnDrawItem 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 OnDrawItem(DrawItemEventArgs) in a derived class, be sure to call the base class's OnDrawItem(DrawItemEventArgs) method so that registered delegates receive the event.
