Hey there!

How can I custom sort DataObjects - means how to sort them independent from it's columns. This was possible with the DataObject Manager Module in SS 2.x and it was great! :-)

Thanks. Mario

I think it's going to be introduced to the core at a later date, but at the moment you need to install this module:

That module works great .. It took me sometime to get it working so here few things that may save you alot of time :
Example for a basic Gallery module = Gallery has_many GalleryImages
** GalleryImage.php
- Make sure you add field for SortID
Code to use :
// to change the default sorting to the new SortID
public static $default_sort = 'SortID Asc';
// To change the Default Value if SortID to LastSortID+1 , basic auto sort
function onBeforeWrite() {
if (!$this->SortID) {
return $this->SortID = $this->getNextSortID();

public function getNextSortID() {
return $this->SGallery()->Images()->Last()->SortID + 1;

** Gallery.php
function getCMSFields() {
$fields = parent::getCMSFields();
$gridFieldConfig = GridFieldConfig_RelationEditor::create();
new GridFieldSortableRows("SortID")
