プロパティ値

ツリー ノードが選択されている場合は true。それ以外の場合は falsetrue if the tree node is in the selected state; otherwise, false.

次のコード例では、 TreeNode TreeNode渡されたが選択されてTreeNodeいるかどうかを判断した後に、適切なを選択します。The following code example selects the appropriate TreeNode after determining if the TreeNode passed in is selected and which TreeNode to select. この例Formでは、複数TreeView TreeNodeのオブジェクトを含むをTreeNodeCollection持つコントロールを持つが必要です。This example requires that you have a Form with a TreeView control that has a TreeNodeCollection containing several TreeNode objects. また、にはComboBox次の項目が含まれている必要があります。"Previous"、"以前に表示されたもの"、"次の"、"NextVisible"、"First"、および "Last"。It also requires that you have a ComboBox with the following items: "Previous", "PreviousVisible", "Next", "NextVisible", "First", and "Last".
