설명

이벤트는 ItemUpdated 컨트롤 내 DetailsView 의 업데이트 단추를 클릭하지만 업데이트 작업 후에 발생합니다. 이렇게 하면 이 이벤트가 발생할 때마다 업데이트 작업의 결과를 확인하는 등 사용자 지정 루틴을 수행하는 이벤트 처리기를 제공할 수 있습니다.

DetailsViewUpdatedEventArgs 개체가 이벤트 처리기에 전달되므로 영향을 받는 행 수와 발생할 수 있는 예외를 확인할 수 있습니다. 예외가 처리 되었는지 여부를 이벤트 처리기를 설정 하 여를 나타낼 수도 있습니다는 ExceptionHandled 속성입니다. 업데이트 작업 후에 컨트롤을 편집 모드로 유지하려면 속성을 true로 설정합니다KeepInEditMode.

이벤트를 처리 하는 방법에 대 한 자세한 내용은 참조 하세요. 이벤트 처리 및 발생합니다.
