ComboBox::OnDrawItem Method (DrawItemEventArgs^)


Raises the DrawItem event.

Namespace:   System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

virtual void OnDrawItem(
	DrawItemEventArgs^ e


Type: System.Windows.Forms::DrawItemEventArgs^

A DrawItemEventArgs that contains the event data.

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 in a derived class, be sure to call the base class's OnDrawItem method so that registered delegates receive the event.
