XML 또는 HTML 요소 중 하나가 구문 분석되었음을 컨트롤에 알리고 해당 요소를 컨트롤의 ControlCollection 개체에 추가합니다.

protected:
 override void AddParsedSubObject(System::Object ^ obj);

protected override void AddParsedSubObject (object obj);

override this.AddParsedSubObject : obj -> unit

Protected Overrides Sub AddParsedSubObject (obj As Object)

매개 변수
