예제

다음 코드 예제에서는 GetWebPart 메서드를 사용하는 방법을 보여 줍니다. 이 예제에는 다음 네 부분이 있습니다.

웹 파트 페이지의 디스플레이 모드를 변경할 수 있게 해 주는 사용자 정의 컨트롤입니다.
두 개의 사용자 지정 WebPart 컨트롤이 포함된 소스 코드 파일입니다.
여러 서버 컨트롤을 CatalogZone 참조하는 컨트롤과 PageCatalogPart 컨트롤이 포함된 웹 페이지입니다. 페이지에는 메서드를 호출 GetWebPart 하는 이벤트 처리 코드도 포함되어 있습니다.
브라우저에서 페이지를 로드할 때 예제가 작동하는 방식에 대한 설명입니다.

이 코드 예제에 첫 번째 부분은 사용자가 웹 페이지의 디스플레이 모드를 변경할 수 있는 사용자 정의 컨트롤입니다. 표시 모드 및 이 컨트롤의 소스 코드에 대한 설명에 대한 자세한 내용은 연습: 웹 파트 페이지에서 디스플레이 모드 변경을 참조하세요.

코드 예제의 두 번째 부분은 두 사용자 지정 WebPart 컨트롤에 대한 소스 코드입니다. 코드 예제를 실행하려면 이 소스 코드를 컴파일해야 합니다. 명시적으로 컴파일하고 결과 어셈블리를 웹 사이트의 Bin 폴더 또는 전역 어셈블리 캐시에 넣을 수 있습니다. 또는 소스 코드를 사이트의 App_Code 폴더에 배치하여 런타임에 동적으로 컴파일할 수 있습니다. 두 가지 컴파일 방법을 모두 보여 주는 연습은 연습: 사용자 지정 웹 서버 컨트롤 개발 및 사용을 참조하세요.
