ItemInserted 컨트롤의 DetailsView 이벤트를 처리하는 메서드를 나타냅니다.

public delegate void DetailsViewInsertedEventHandler(System::Object ^ sender, DetailsViewInsertedEventArgs ^ e);

public delegate void DetailsViewInsertedEventHandler(object sender, DetailsViewInsertedEventArgs e);

type DetailsViewInsertedEventHandler = delegate of obj * DetailsViewInsertedEventArgs -> unit

Public Delegate Sub DetailsViewInsertedEventHandler(sender As Object, e As DetailsViewInsertedEventArgs)

매개 변수

sender: Object

이벤트 소스입니다.

e: DetailsViewInsertedEventArgs

이벤트 데이터를 포함하는 DetailsViewInsertedEventArgs입니다.

예제

다음 코드 예제에서는 프로그래밍 방식으로 추가 하는 방법에 설명를 DetailsViewInsertedEventHandler 위임할 합니다 ItemInserted 의 이벤트를 DetailsView 컨트롤.

설명

DetailsView 를 발생 시킵니다를 ItemInserted 때 삽입 단추 이벤트 (단추를 사용 하 여 해당 CommandName "Insert"로 설정 하는 속성) 컨트롤 내에서 클릭 한 후는 DetailsView 레코드를 삽입 합니다. 이 옵션을 사용 하면이 이벤트가 발생할 때마다 삽입 작업의 결과 확인 하는 등 사용자 지정 루틴을 수행 하는 이벤트 처리기를 제공할 수 있습니다.

DetailsViewInsertedEventHandler 대리자를 만들 때, 이벤트를 처리할 메서드를 식별합니다. 이벤트를 이벤트 처리기와 연결하려면 대리자의 인스턴스를 해당 이벤트에 추가합니다. 대리자를 제거하지 않는 경우 이벤트가 발생할 때마다 이벤트 처리기가 호출됩니다. 이벤트 처리기 대리자에 대 한 자세한 내용은 참조 하세요. 이벤트 처리 및 발생합니다.
