Hi Sir,
I used the code you mentioned above, but it was not exactly the result i want.
In your code, the calculated column value could be rd.qty * rd.price. It's correct. But in the Summarydata row, the value of this cell will be calculated with the same logic in above cells: sum(rd.qty) * sum(rd.price). In my case, we cannot calculate list this.
Please see attached screenshot and you may get a better understand to what i actually asked. The formula marked in Red is the one pqgrid provides and the formula marked in Green will be the one i want to achieve.
Thanks a lot in advance.
