ComboBox.OnDrawItem Method

Raises the DrawItem event.

[Visual Basic]
Protected Overridable Sub OnDrawItem( _
   ByVal e As DrawItemEventArgs _
)
[C#]
protected virtual void OnDrawItem(
 DrawItemEventArgs e
);
[C++]
protected: virtual void OnDrawItem(
 DrawItemEventArgs* e
);
[JScript]
protected function OnDrawItem(
   e : DrawItemEventArgs
);

Parameters

e
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 Raising an Event.

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.

Requirements
