I have fix to this problem after modification of some part of the jquery.jqgrid.js file.

i am trying to post the code here somehow getting error. is there way i can attach js file here?

Hi Tony, Even i am facing same problem just like steve. jqgrid always gives precedence to left most column for multisort.i was looking in detail at jquery.jqgrid.js for multi sort and what i felt that it always look at in colmodel sequence to append sort name . line 2239

ts.p.sortorder = “”;
            $.each(cm, function(i){
                if(this.lso) {
                    if(i>0 && fs) {
                        sort += “, “;
                    }
                    splas = this.lso.split(“-“);
                    sort += cm.index || cm.name;
                    sort += ” “+splas[splas.length-1];
                    fs = true;
                    ts.p.sortorder = splas[splas.length-1];
                }
            });
            ls = sort.lastIndexOf(ts.p.sortorder);
            sort = sort.substring(0, ls);
            ts.p.sortname = sort;
