title: How to get jqGrid reload to go to server?
body: <p>We use the jqGrid navigator reload button on a grid with <code>loadonce</code> set to true.  </p>
  
  <p>The reload button currently does NOT go back to the server to get the data - how can we get the reload to go to the server to get the latest data?</p>
  
  <p>I believe we can use the <a href="http://www.trirand.com/jqgridwiki/doku.php?id=wiki:navigator" rel="noreferrer"><code>beforeRefresh</code></a> callback to set the grid <code>data</code> to <code>json</code> instead of <code>local</code> but I'm not clear how to even configure the <code>beforeRefresh</code> method - I don't really understand the docs.</p>
