you can do it by selecting a different node at run time but it will rise the AfterSelect event again.
why do you need that for?

in my after select event i open sub forms,
after user select the node a sub form open,
after a while if the user close the form, and again click the same nose
if it is already selected then it isn't open the form,
because after select event isn't work,
becouse it is already selected

this will select the root:

Me.TreeView1.SelectedNode=Me.TreeView1.Nodes(0)

You can unselect the node after it has been selected like this:

    Private Sub TreeView1_AfterSelect1(ByVal sender As Object, ByVal e As System.Windows.Forms.TreeViewEventArgs) Handles TreeView1.AfterSelect
        ' Do some stuff in here
        TreeView1.SelectedNode = Nothing
    End Sub
