EventArgs 매개 변수가 ItemCommand의 인스턴스인 경우 RepeaterCommandEventArgs 이벤트를 발생시킵니다.

protected:
 override bool OnBubbleEvent(System::Object ^ sender, EventArgs ^ e);

protected override bool OnBubbleEvent (object sender, EventArgs e);

override this.OnBubbleEvent : obj * EventArgs -> bool

Protected Overrides Function OnBubbleEvent (sender As Object, e As EventArgs) As Boolean

매개 변수

sender: Object

이벤트 소스입니다.

e: EventArgs

이벤트 데이터가 포함된 EventArgs 개체입니다.

반환

Boolean

ItemCommand가 발생되었으면 true이고, 그렇지 않으면 false입니다.

예제

다음 코드 예제에서는 재정의 OnDataBinding 하는 방법을 보여 줍니다는 메서드를 사용자 지정 서버 컨트롤에서 이벤트 인수는 명령 형식인 Repeater 경우 컨트롤은 항상 호출 OnItemCommand 하 고 이벤트를 버블, 또는 반환 false 하 고 이벤트를 취소 합니다.
