  • 참조

정의

네임스페이스:
System.Web.UI.WebControls
어셈블리:
System.Web.dll

지정된 TreeNodeBinding 개체를 TreeNodeBindingCollection 개체의 지정된 인덱스 위치에 삽입합니다.

public:
 void Insert(int index, System::Web::UI::WebControls::TreeNodeBinding ^ binding);
public void Insert (int index, System.Web.UI.WebControls.TreeNodeBinding binding);
member this.Insert : int * System.Web.UI.WebControls.TreeNodeBinding -> unit
Public Sub Insert (index As Integer, binding As TreeNodeBinding)

매개 변수

index

TreeNodeBinding을 삽입할 인덱스 위치(0부터 시작)입니다.

binding
TreeNodeBinding

삽입할 TreeNodeBinding입니다.

예제

다음 코드 예제를 사용 하는 방법에 설명 합니다 Insert 새로 삽입 하는 방법 TreeNodeBinding 개체를 프로그래밍 방식으로 TreeNodeBindingCollection 개체입니다. 이 예제가 제대로 작동 하려면에 대 한 Book.xml 라는 파일에이 섹션의 끝에 있는 XML 데이터를 복사 해야 합니다.
