title: DataFormatString in my Gridview does not work in SharePoint
body: <p>I have a ASP.NET GridView that i created on a page through SharePoint Designer 2007.
  For some reason it just does not want to work, why is that and how can i Fix it?</p>
  
  <p>Funny thing, it worked on another SharePoint Server but not on the one i am working on now, so i know my code is fine, it must be something ells on the SharePoint Server maybe?</p>
  
  <p>My Currency DataFormatStrings also dont want to work on my current SharePoint Server.</p>
  
  <p>My DataFormatString for my Date field</p>
  
  <pre><code>&lt;asp:BoundField DataField="c505_remdate" HeaderText="Remit. Advice Date" 
   SortExpression="c505_remdate" DataFormatString="{0:d/MM/yyyy}" /&gt;
  </code></pre>
