예제

다음 예제에서는 특정 열에 있는 모든 셀의 모양을 사용자 지정 하려면이 이벤트의 사용을 하는 방법을 보여 줍니다.The following example illustrates the use of this event to customize the appearance of all cells in a particular column.

이 코드는에서 사용할 수 있는 보다 큰 예제의 일부 방법: Windows Forms DataGridView 컨트롤에서 셀 모양 사용자 지정합니다.This code is part of a larger example available in How to: Customize the Appearance of Cells in the Windows Forms DataGridView Control.

설명

DataGridViewCellPaintingEventHandler 대리자를 만들 때, 이벤트를 처리할 메서드를 식별합니다.When you create a DataGridViewCellPaintingEventHandler delegate, you identify the method that will handle the event. 이벤트를 이벤트 처리기와 연결하려면 대리자의 인스턴스를 해당 이벤트에 추가합니다.To associate the event with your event handler, add an instance of the delegate to the event. 대리자를 제거하지 않는 경우 이벤트가 발생할 때마다 이벤트 처리기가 호출됩니다.The event handler is called whenever the event occurs, unless you remove the delegate. 이벤트 처리기 대리자에 대 한 자세한 내용은 참조 하세요. 이벤트 처리 및 발생합니다.For more information about event-handler delegates, see Handling and Raising Events.
