설명

이 속성 설정 된 경우 true에 스크롤 막대가 표시 됩니다는 TreeView 있으면 TreeNode 컨트롤의 클라이언트 영역 외부에 위치한 합니다.If this property is set to true, scroll bars are displayed on the TreeView when any TreeNode is located outside the control's client region.

참고

설정 하는 경우는 Scrollable 런타임 시 속성을 TreeView 핸들을 다시 만드는 (참조 Control.RecreateHandle) 컨트롤의 모양을 업데이트 합니다.When setting the Scrollable property at run time, the TreeView handle is recreated (see Control.RecreateHandle) to update the control's appearance. 이렇게 하면 선택한를 제외 하 고 축소 하는 모든 트리 노드 TreeNode합니다.This causes all tree nodes to be collapsed, with the exception of the selected TreeNode.
