[eluser]bhakti.thakkar[/eluser]
i tried to use a simple table of country to make it work. Now atleast my flexigrid gets loaded but still with no data in it. it just comes processing, please wait.... what could be possible mistake?? there are 237 rows.
in ajax.php controller

Code:

foreach ($records['records']->result() as $row)
        {
            $record_items[] = array($row->Country_ID,
            $row->Country_ID,
            $row->Country_VC,
            '<a ><img >config->item('base_url').'public/images/close.png\'></a> '

            );
        }
