This is very easy but tricky. By default HideSelection property of treeview is true. So it confuses many programmer. When you use Treeview.Selected=True and HideSelection is True then it wont show the selection even though node is selected. Check the following example for that

Click here to copy the following block
Private Sub Command1_Click()
  TreeView1.Nodes("b1").Selected = True
  '///////////////////////////////////////////////
  'or
  '///////////////////////////////////////////////
  'Set TreeView1.SelectedItem = TreeView1.Nodes("b1")
  
  '///////////////////////////////////////////////
  '//Starting Label Edit with node select
  'TreeView1.StartLabelEdit
  '///////////////////////////////////////////////
End Sub

Private Sub Form_Load()
  TreeView1.HideSelection = False

  TreeView1.Nodes.Add , , "root", "root"
  TreeView1.Nodes.Add "root", tvwChild, "a1", "a1"

  TreeView1.Nodes.Add "a1", tvwChild, "a1-1", "a1-1"
  TreeView1.Nodes.Add "a1", tvwChild, "a1-2", "a1-2"

  TreeView1.Nodes.Add "root", tvwChild, "b1", "b1"
  TreeView1.Nodes.Add "b1", tvwChild, "b1-1", "b1-1"
  TreeView1.Nodes.Add "b1", tvwChild, "b1-2", "b1-2"

  TreeView1.Nodes.Add "root", tvwChild, "c1", "c1"
End Sub
