속성 값
tree view 컨트롤에 할당된 트리 노드를 나타내는 TreeNodeCollection입니다.
설명
Nodes 속성은 각각 해당 TreeNodeCollection을 포함할 수 있는 Nodes 속성을 갖는 TreeNode 개체의 컬렉션을 보유합니다. 이렇게 트리 노드가 중첩되면 트리 구조를 탐색하기 어려울 수 있으나 FullPath 속성으로 트리 구조 내의 사용자 위치를 보다 쉽게 확인할 수 있습니다.
예제
다음 코드 예제에서는 TreeView 컨트롤에 고객 정보를 표시합니다. 루트 트리 노드에는 고객 이름이 표시되고 자식 트리 노드에는 각 고객에게 할당된 주문 번호가 표시됩니다. 이 예제에서는 주문을 15개씩 보유하고 있는 1000명의 고객이 표시됩니다. BeginUpdate 및 EndUpdate 메서드를 사용하여 TreeView의 다시 그리기가 억제되고 TreeView에서 TreeNode 개체를 만들고 그리는 동안 대기 중인 Cursor가 표시됩니다. 이 예제를 실행하려면 Order 개체의 컬렉션을 저장할 수 있는 Customer 개체가 있어야 합니다. 또한 Form에 TreeView 컨트롤의 인스턴스가 있어야 합니다.
