I was facing similar issue. I have resolved it using custom function for validation. I am suing date format as '23-Jan-05'. You may modify it to suit your required date format.

function datecheck(value, colname) {
            var dateParts = value.split("-");
            var datePart = dateParts[0];
            var mounth = dateParts[1];
            var yearPart = dateParts[2];

            var mounths = $.jgrid.formatter.date.monthNames;
            var monthPart = -1;
            for (var i = 0; i < 12; i++) {
                if (mounth === mounths[i]) {
                    monthPart = i + 1;
                    break;
                }
            }
            var dateText = monthPart + '-' + datePart + '-' + yearPart;
            var date = Date.parse(dateText);
            if (isNaN(date)) 
                return [false,"Invalid date. Format expected: dd-mmm-yy. (23-Jul-05)"];
            else 
            return [true,""];                  

        }

JQGrid column details:

colModel: [name: 'JoiningDate', align: "center", editable: true, 
           editrules: { custom: true, custom_func: datecheck },
           formatter: 'date', formatoptions: { srcformat: 'y-m-d', newformat: 'd-M-y' }, edittype: 'text', editable: true,
           editoptions: { dataInit: function (el) { setTimeout(function () { $(el).datepicker({ dateFormat: 'd-M-y' }); }, 200); } }
            },

Hope this helps.
