DhtmlxGrid Sorting on equal values

Hi ,

I have written my custom sorting function , and it is working fine when the values are unequal , but when all the values are equal , the grid appears to be refreshed , ideally it should not since all values are equal .

Following is the snippet from javascript function , however its not working.Could you please help me in refining the logic.

if (a==b) {

                    return // what ; I tried with 0 but not working


                if (order==“asc”) {

                return (a>b?1:-1);



                 else {

            return (a<b?1:-1);
