	e As DrawItemEventArgs _
)

protected virtual void OnDrawItem(
	DrawItemEventArgs e
)

protected:
virtual void OnDrawItem(
	DrawItemEventArgs^ e
)

abstract OnDrawItem : 
        e:DrawItemEventArgs -> unit 
override OnDrawItem : 
        e:DrawItemEventArgs -> unit

Parameters

e: Type: System.Windows.Forms..::.DrawItemEventArgs
A DrawItemEventArgs that contains the event data.

Remarks

Raising an event invokes the event handler through a delegate. For more information, see Raising an Event.

The OnDrawItem 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.

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.
