예제

다음 코드 예제에서는 두 가지를 보여 줍니다. 먼저 , 라는 MyWebPartChrome파생 CreateWebPartChrome 영역에서 메서드를 재정의하여 사용자 지정 클래스 WebPartZoneBase 의 MyZone 새 인스턴스를 만듭니다. 둘째, 클래스의 MyWebPartChrome 생성자에서 클래스 내에서 사용할 수 있는 프라이빗 필드에 생성자의 매개 변수에 있는 개체를 할당합니다. 따라서 이 예제에서는 생성자 WebPartManager 에서도 연결된 영역 및 Zone 개체에 액세스하고 속성에 WebPartManager 액세스할 수 있는 방법을 제공합니다. 마지막으로 생성자가 작동하려면 메서드 선언의 일부로 기본 생성자도 호출해야 합니다.

다음 코드에는 두 개의 사용자 지정 클래스가 포함되어 있습니다. 이러한 컨트롤을 호스트하는 웹 페이지를 포함하여 예제를 실행하는 데 필요한 전체 코드는 클래스 개요 항목의 예제 섹션을 WebPartChrome 참조하세요.
