속성 값

자식 디자이너가 들어 있는 ActivityDesigner 읽기 전용 컬렉션입니다.

예제

다음 예제에서는 CompositeActivityDesigner 클래스에 기반을 둔 디자이너를 사용하여 새 분기를 추가하는 방법을 보여 줍니다. CanInsertActivities가 true를 반환할 경우에는 새 분기는 InsertActivities 메서드를 사용하여 만들어집니다. ConnectorHitTestInfo 개체는 InsertActivities 메서드에 대한 매개 변수로 만들어집니다. 완료되면 EnsureVisibleContainedDesigner 메서드로 ContainedDesigners 컬렉션의 단일 개체에 액세스하여 새로 추가된 분기가 워크플로 디자이너에 표시되는지 확인합니다.
