If you mean total number of rows in grid - it is not possible by API, can be made by code modification, by actually much more easy to implement just as separate code

<form onsubmit="do_things()"...
    <input type="hidden" name="total">


<script>
    function do_things(){
       document.forms[0].total.value=mygrid.getRowsNum();
    }
</script>
