System.Windows.Forms.ComboBox.OnDrawItem Method

Raises the ComboBox.DrawItem event.

Syntax

protected virtual void OnDrawItem (DrawItemEventArgs e)

Parameters

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

Remarks

This method is called each time an owner-drawn System.Windows.Forms.ComboBox item needs to be drawn and after ComboBox.OnMeasureItem(MeasureItemEventArgs) is called. For more information, see ComboBox.DrawItem.

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

The ComboBox.OnDrawItem(DrawItemEventArgs) 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.
