public System.Windows.Forms.TreeView TreeView { get; }
member this.TreeView : System.Windows.Forms.TreeView
Public ReadOnly Property TreeView As TreeView

屬性值

表示父樹狀檢視的 TreeView,會將樹狀節點指派給該父樹狀檢視;如果尚未指派節點給樹狀檢視,則為 nullA TreeView that represents the parent tree view that the tree node is assigned to, or null if the node has not been assigned to a tree view.

範例

下列程式碼範例會在決定TreeNode是否選取了傳入TreeNode的之後,再TreeNode選取適當的。The following code example selects the appropriate TreeNode after determining if the TreeNode passed in is selected and which TreeNode to select. 這個Form範例要求您的具有TreeView具有包含多個TreeNode物件之的TreeNodeCollection控制項。This example requires that you have a Form with a TreeView control that has a TreeNodeCollection that contains several TreeNode objects. 此外,您也需要具有ComboBox具有下列專案的:[上一步]、[PreviousVisible]、[下一步]、[NextVisible]、[第一個] 和 [最後一步]。It also requires that you have a ComboBox with the following items: "Previous", "PreviousVisible", "Next", "NextVisible", "First", and "Last".
