title: order of rows in a datagrid in Flex
body: <p>I have a datagrid and it lists several rows as</p>
  
  <pre><code>seqno | NAME  | COMPANY
  1     | BOB   | D&amp;T
  2     | Jenny | M&amp;Y
  3     | Jane  | D&amp;T
  </code></pre>
  
  <p>It is possible to have buttons as [<code>MOVE UP</code>] and [<code>MOVE DOWN</code>] so that when I select a row in a datagrid and press one of those button that the order changes and the seqno updates accordingly.</p>
  
  <p>Meaning if I select <code>Jane</code> and press the [<code>MOVE UP</code>] button, the new order would be;</p>
  
  <pre><code>seqno | NAME  | COMPANY
  1     | BOB   | D&amp;T
  2     | Jane  | D&amp;T
  3     | Jenny | M&amp;Y
  </code></pre>
  
  <p>All help is appriciated</p>
