vb net treeview控件如何设置某节点被选择

使用哪个方法

Answer 1

TreeView的SelectedNode属性获取或设置当前选择的节点。

TreeView1.SelectedNode = TreeView1.Nodes(1) '选择第二个节点

Answer 2

我也不怎么用,你自己推敲一下
TreeView1.Nodes.Item(3).Selected = True

Answer 3

Me.TreeView1.SelectedNode =Me.TreeView1.Nodes(key or index )

相关的vb.net treeview控件有：
Public Class MyNode
Inherits TreeNode
Public ID as Integer
Public ParentID as Integer
End Class

Public Class MyTreeView
Inherits TreeView
Public mNode as MyNode
Public Sub Add(Node as MyNode)
...
End Sub
...
End Class
