vB中trEEviEw如何选中节点?

Private Sub TreeView1_NodeClick(ByVal Node As MSComctlLib.Node) If TreeView1.SelectedItem.Children = 0 Then '检查是否有子节点,0为无 For I = 1 To TreeView1.Nodes.Count If TreeView1.Nodes(I).Selected Then MsgBox "您选择的是:“" &...

Private Sub TreeView1_NodeClick(ByVal Node As MSComctlLib.Node) If TreeView1.SelectedItem.Children = 0 Then '检查是否有子节点,0为无 For I = 1 To TreeView1.Nodes.Count If TreeView1.Nodes(I).Selected Then MsgBox "您选择的是:“" &...

Private Sub Command1_Click() Dim i As Integer Dim nd As Node List1.Clear Set nd = TreeView1.SelectedItem.Child For i = 1 To TreeView1.SelectedItem.Children List1.AddItem nd.Text Set nd = nd.Next Next End Sub Private Sub Form_Lo...

写在 TreeView 的 AfterSelect 事件过程中: Try With e.Node Select Case .Text Case "第一个节点" ……

'试试下面两个属性为真 treeview1.Nodes(index).Selected = True treeview1.Nodes(index).EnsureVisible =True

操作方法是: /// /// 获取指定value值的节点 /// /// 指定节点 /// value值 /// private TreeNode FindNodeByValue(TreeNode tnParent, string strValue) { if (tnParent == null) return null; if (tnParent.Value == strValue) return tnPare...

Public Class Form1 Dim node(5) As TreeNode Private Sub Form1_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load Dim root As TreeNode With TreeView1 .Nodes.Clear() .ShowLines = True .ShowPlusMinus = True ....

你需要的是不是选中节点后,节点的文字(节点名称)改变颜色? 如果是的话,只要在 private void treeView1_BeforeSelect(object sender, TreeViewCancelEventArgs e)事件中增加语句: e.Node.ForeColor = 颜色 ,比如写入以下语句 { e.Node.For...

index n属性。
