I'm not sure I'm completely following you here. The controls are displayed when the index is 1 right? What else are you expecting to occur? Also, check that you have at least 2 nodes in the treeview since the index is zero based.

TreeViewEventArgs has all the properties you need. You can use them right away. Apart from that what exactly is the problem you are facing.

I tried the aabove code by making a button visable false and on selcting a perticular treenode it will appear but the same code is not working for the group box that consits of some group of buttons. I want make that group box visable when i click on a perticular treeview node.

Your code looks like it should work. Check the visible property (should be true) on the button controls in the group box to see if visible = true. If not, you'll need to change that at design time or during run time looping the groupbox's control collection. Quick test app you can do.

Private Sub Form1\_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
    'add a group box and stuff with button controls 
    For Each ctl As Control In GroupBox1.Controls 
        ctl.Visible = True
    Next

    GroupBox1.Visible = False
End Sub

Private Sub TreeView1\_AfterSelect(ByVal sender As System.Object, ByVal e As System.Windows.Forms.TreeViewEventArgs) Handles TreeView1.AfterSelect
    If e.Node.Index = 5 Then
        GroupBox1.Visible = True
    End If
End Sub
