설명

페이징을 사용하도록 설정하면(속성을 true로 설정 AllowPaging 하여) 호출기 행이라는 추가 행이 컨트롤에 DetailsView 자동으로 표시됩니다. 호출기 행에는 사용자가 다른 레코드로 이동할 수 있는 컨트롤이 포함되어 있으며 컨트롤의 위쪽, 아래쪽 또는 위쪽과 아래쪽 모두에 표시될 수 있습니다. 사용 된 TopPagerRow 속성을 프로그래밍 방식으로 액세스 하는 컨트롤의 DetailsViewRow 위쪽 호출기 행 DetailsView 을 나타내는 개체입니다.

참고

속성은 TopPagerRow 컨트롤이 DetailsView 이벤트에서 아래쪽 호출기 행 ItemCreated 을 만든 후에만 사용할 수 있습니다.

이 속성은 사용자 지정 콘텐츠를 추가할 때와 같이 위쪽 호출기 행을 프로그래밍 방식으로 조작해야 하는 경우에 일반적으로 사용됩니다. 컨트롤이 TopPagerRow 렌더링된 후에 DetailsView 는 속성을 수정해야 합니다. 그렇지 않으면 컨트롤이 DetailsView 변경 내용을 덮어쓰게 됩니다.
