설명

머리글 행은 또는 HeaderTemplate 속성이 DetailsView 설정될 때 HeaderText 컨트롤의 맨 위에 표시됩니다. 사용 된 HeaderRow 속성을 프로그래밍 방식으로 헤더 행을 DetailsViewRow 나타내는 개체에 액세스 합니다.

참고

속성은 HeaderRow 컨트롤이 이벤트에서 헤더 행 ItemCreated 을 DetailsView 만든 후에만 사용할 수 있습니다.

이 속성은 헤더 행을 프로그래밍 방식으로 조작해야 하는 경우(예: 사용자 지정 콘텐츠를 추가할 때) 일반적으로 사용됩니다. 컨트롤이 HeaderRow 렌더링된 후에 DetailsView 는 속성을 수정해야 합니다. 그렇지 않으면 컨트롤이 DetailsView 변경 내용을 덮어쓰게 됩니다.
