jQuery Grid Plugin - jqGrid

Hi,

Am am new to this and jquery so please forgive me if this is a basic question!  I am trying to use the new "setFrozenColumns" method in my grid.  I have downloaded ans installed version 4.3 and cant figure out how it works.  I use ajax to load data into my grid, including the column model etc.  Here is my code (all works perfectly except the freeze):

<script type="text/javascript">
$(document).ready(function () {

    $.ajax({
        
        type: "GET",
        url: "xxxxxxxxxx",
        dataType: "json",

        success: function(result){
            
            var colD = result.pfcTills,
            colM = result.colModelList;
                
            <!--- BEGIN: Build Grid --->
            $("#dataGrid").jqGrid({
                
                datatype: 'local',
                data: colD.rootVar,
                gridview: true,
                colModel :colM,
                height: "100%",
                width: 1000,
                shrinkToFit: false,
                caption:"PFC TILLS MONTHLY SUMMARY",
                sortable: true,
                rowNum: 100
            });
            <!--- END: Build Grid --->

        },
        
        error: function(x, e){ alert(x.readyState + " "+ x.status +" "+ e.msg); }

    });

});
</script>

I have also <cfset tmp2.frozen = true> in my colModelList.  Where in my code should this go:

jQuery("#dataGrid").jqGrid('setFrozenColumns');

And while we are at it, how do i colour a selected row?

Any help greatly appreciated.  I need to sort this to show the boss man before we purchase it.

Thanks.
