Hi Guys,

I want to sort my GridField based on a casted value in my DataObject;

In my DataObject, summary_fields i point to a function DownloadsNum;
static $summary_fields = array(
'FirstName' => 'Varchar',
'Surname' => 'Varchar',
'Email' => 'Varchar(256)',
'DownloadsNum' => 'Downloads'
);

public function DownloadsNum(){
$do = DataObject::get("TrackDownload", "MemberID ='".$this->ID."'");
return $do->count();
}
This is working, i see the values in my GridField. How can i put this column to a descending order by default?

Hope someone can help.
Thx
Joe
