注釈

このイベントは、ノードが選択されていない場合には発生しません。This event does not occur when the node is unselected. 選択がクリアされたかどうかを検出するTreeNode.IsSelectedには、プロパティをテストします。To detect whether the selection was cleared, you can test the TreeNode.IsSelected property.

イベントの処理の詳細については、「処理とイベントの発生」を参照してください。For more information about handling events, see Handling and Raising Events.
