WebPartConnection.ConsumerConnectionPointID 속성

public:
 property System::String ^ ConsumerConnectionPointID { System::String ^ get(); void set(System::String ^ value); };

public string ConsumerConnectionPointID { get; set; }

member this.ConsumerConnectionPointID : string with get, set

Public Property ConsumerConnectionPointID As String

속성 값

소비자 연결 지점의 ID가 들어 있는 문자열입니다.

예제

다음 코드 예제에서는 선언적이 고 프로그래밍 방식으로 사용 하는 ConsumerConnectionPointID 속성입니다.

이 예제에는 네 부분으로 구성합니다.

• 페이지에서 웹 파트 표시 모드를 변경할 수 있는 사용자 컨트롤입니다.

• 연결에 대한 공급자 및 소비자 역할을 하는 인터페이스 및 두 컨트롤 WebPart 에 대한 소스 코드입니다.

• 모든 컨트롤을 호스트하고 코드 예제를 실행하는 웹 페이지입니다.

• 예제 페이지를 실행하는 방법에 대한 설명입니다.

이 코드 예제에 첫 번째 부분은 사용자가 웹 페이지의 디스플레이 모드를 변경할 수 있는 사용자 정의 컨트롤입니다. 다음 소스 코드를 .ascx 파일에 저장하여 호스팅 웹 페이지의 맨 위에 있는 이 사용자 컨트롤에 대한 지시문의 Register 특성에 할당된 Src 파일 이름을 제공합니다. 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 인터페이스의 소스 코드와 소비자 및 공급자 컨트롤입니다. 코드 예제를 실행하려면 이 소스 코드를 컴파일해야 합니다. 명시적으로 컴파일하고 결과 어셈블리를 웹 사이트의 Bin 폴더 또는 전역 어셈블리 캐시에 넣을 수 있습니다. 또는 런타임에 동적으로 컴파일되는 사이트의 App_Code 폴더에 소스 코드를 배치할 수 있습니다. 이 코드 예제에서는 동적 컴파일을 사용합니다. 컴파일 방법을 보여 주는 연습은 연습: 사용자 지정 웹 서버 컨트롤 개발 및 사용을 참조하세요.

코드 예제의 세 번째 부분은 웹 페이지입니다. 연결은 및 <asp:WebPartsConnection> 요소를 사용하여 페이지 태그에 <StaticConnections> 선언됩니다. 연결 선언에는 필수 ConsumerConnectionPointID 특성이 포함됩니다. 연결을 만드는 두 번째 메서드가 메서드에 Button1_Click 나타납니다. 여기서 코드는 소비자 컨트롤에 정의된 연결 지점을 사용하여 새 연결을 만듭니다. 그런 다음 메서드에서 Button2_Click 코드가 속성에 ConsumerConnectionPointID 액세스합니다.

브라우저에서 페이지를 로드한 후 페이지에 선언된 정적 연결로 인해 연결이 이미 존재합니다. 공급자 컨트롤에 일부 텍스트를 입력하고 연결로 인해 소비자에게 표시됩니다. 다음으로 컨트롤의 연결을 끊습니다. 디스플레이 모드 드롭다운 목록 컨트롤을 사용하여 페이지를 연결 모드로 전환합니다. 컨트롤 중 WebPart 하나에서 동사 메뉴(제목 표시줄의 아래쪽 화살표로 표시됨)를 클릭하고 연결 동사를 클릭합니다. 연결 끊기 단추를 클릭합니다. WebPart 컨트롤 연결 단추를 사용하여 두 컨트롤 간의 연결을 다시 만듭니다. ConnectionPoint 세부 정보 단추를 클릭하여 속성 값에 ConsumerConnectionPointID 액세스하는 코드를 실행합니다. 값은 컨트롤 아래의 레이블에 기록됩니다.

설명

웹 페이지의 태그에 선언된 정적 연결의 경우 개발자는 요소의 특성에 값을 ConsumerConnectionPointID 할당하여 연결에 <asp:webpartconnection> 사용할 소비자 연결 지점을 지정할 수 있습니다. 값이 특성 DefaultID 에 할당되지 않은 경우 속성 값이 사용됩니다.

동적(프로그래밍 방식) 연결을 만들 때는 일반적으로 속성 값을 ConsumerConnectionPointID 설정하면 안 됩니다. 컨트롤에서 메서드를 ConnectWebPartsWebPartManager 호출하여 소비자 및 소비자 연결 지점 개체(다른 필수 매개 변수와 함께)에 전달할 수 있으며, 해당 메서드는 소비자의 연결 지점에 사용할 올바른 ID를 결정합니다. 마찬가지로 연결을 끊을 때 속성 값을 지정할 ConsumerConnectionPointID 필요 없이 메서드를 호출 DisconnectWebParts 할 수 있습니다.
