When you start typing Alphanumeric characters when a tree has focus the nodes will automatically select the node starting with the character. I don't want the selection to happen but the following code doesn't stop it.

private void OnKeyDownTree(object sender, KeyEventArgs e)
{
   if (IsAlphaNumeric(e.KeyValue))
   {
      e.Handled = true;
   }
}

Anyone have any ideas on how to have an UltraTree ignore Alphanumeric characters so the nodes don't get selected?

thanks
