Hi there,

I want to control over a Pages children on which one every got a field Date. Instead of using the order which is given by drag and drop in the backend, I want to sort the children by the datefield. How do I implement this?

You could add a method to your class, that returns the child pages, sorted by date:

// this method belongs to your Page Class
// or the class that holds the sortable children
public function SortedChildren(){
   // $children will be a DataObjectSet
   $children = $this->Children();

   if( !$children )
      return null; // no children, nothing to work with

   // sort the DataObjectSet
   // see http://doc.silverstripe.com/doku.php?id=dataobjectset#sorting
   $children->sort('Date');

   // return sorted set
   return $children;
}

The function has to be in the Controller Class.

then you'll be able to acess your Custom-Sorted Children in the Template via:

<% control SortedChildren %>

$Date
      
<% end_control %>

cheers.

I'm trying to get this to work on DataObject within a Children.GroupedBy control and I'm not getting any results. Anyone tried this?
