$page = $_GET['page']; // get the requested page
$limit = $_GET['rows']; // get how many rows we want to have into the grid
$sidx = $_GET['sidx']; // get index row – i.e. user click to sort
$sord = $_GET['sord']; // get the direction if(!$sidx) $sidx =1;

does this look familiar ?

i use this sample code the you provide from the demo app, but on IE8 .. sometimes i cant figure it out when and how

$page and $limit are blank ! and my sql query crashes
