Sorting DOM objects on the front end

I built a FDOM like so:

$manager = new FileDataObjectManager(
$this, // Controller
'Resources', // Source name
'Resource', // Source class
'Attachment', // File name on DataObject
'Name' => 'Name',
), // Headings
'getCMSFields_forPopup', // Detail fields (function name or FieldSet object)
'',// Filter clause
'Name ASC'// Sort clause
// Join clause

The data objects are always sorted as I'd like in the CMS, but how do I get them to display the same way in the template?

<% control Resources %>
<tr class="$EvenOdd">
<td class="left">$Name</td>
<td><a href="$Attachment.URL" target="_blank">Download</a></td>
<% end_control %>

You can add a $default_sort property to your Resource object..

static $default_sort = "Title ASC";

Perfect. Thank you for the fast response (and your overall dedication to the SS community)!

What if you are trying to sort by the "Attachment" instead of "Title". Since Attachment is part of the $has_one array instead of the $db array, it has no actual entry, but rather is represented by the "AttachmentID" field. How do I go about sorting by the actual attachment name?

class Resource extends DataObject
   static $db = array (
      'Name' => 'Text',
      'Description' => 'Text'


   static $has_one = array (
      'Attachment' => 'File',
      'ReportPage' => 'ReportPage'
   static $default_sort = "AttachmentID ASC"; // Doesn't actually sort by Attachment name
   public function getCMSFields_forPopup()
      return new FieldSet(
         new TextField('Name'),
         new TextareaField('Description'),
         new FileIFrameField('Attachment')
