예제

다음 코드 예제에는 선언적으로 설정 하는 방법을 보여 줍니다.는 HeaderText 속성을 BoundField 의 열 머리글의 텍스트를 표시할 열을 GridView 컨트롤입니다. 이 코드 예제는 마스터-세부 시나리오를 보여 줍니다.는 GridView 컨트롤을 사용 하는 동안 데이터의 하위 집합을 표시 하는 DetailsView 더 큰 데이터 집합을 표시 하 고 새 레코드를 삽입 컨트롤을 사용 합니다. 예제에서는 두 개의 SqlDataSource 컨트롤: 채우고 합니다 GridView 컨트롤과 채우고는 DetailsView 제어 하 고 데이터를 삽입 합니다.

설명

사용 된 HeaderText 친숙 한 이름의 데이터 컨트롤에 있는 필드를 식별 하는 속성입니다. 가장 일반적인 애플리케이션을 HeaderText 속성이 데이터 바인딩 필드에 대 한 의미 있는 열 이름을 제공 하는 GridView 또는 DetailsView 컨트롤입니다.

참고

모두를 HeaderTextHeaderImageUrl 속성을 설정 합니다 HeaderImageUrl 속성이 우선 합니다.

이 속성의 값으로 설정 된 경우 디자이너 도구를 사용 하 여 리소스 파일에 자동으로 저장 될 수 있습니다. 자세한 내용은 LocalizableAttribute 하 고 전역화 및 지역화합니다.
