Focus()

[RealNickyDude]

After selecting something from a Treeview, how do I shift focus to something else? Here's the code:

Private Sub TreeView1_AfterSelect(ByVal sender As System.Object, ByVal e As System.Windows.Forms.TreeViewEventArgs) Handles TreeView1.AfterSelect
        Try
            CodeDirectory = e.Node.Parent.Text
            code = "code\" & CodeDirectory & "\" & e.Node.Text & ".rtf"
            rtbcodewindow.LoadFile(code, RichTextBoxStreamType.RichText)
        Catch ex As Exception
            'MessageBox.Show(ex.Message)
        End Try
        [b]rtbcodewindow.Focus()[/b]
    End Sub

I thought rtbcodewindow.Focus() would automatically shift the focus to the RichTextBox called rtbcodewindow, but it doesn't.

Anyone any ideas?
