Just use the sum aggregate in an SQL query to sum all records. Example: select sum(price) as total from articles

When I did that I did something like total += the cell value. I did that from RowAdded or RowDataBound. I can't remember the exact name, but every time a row is added the total would be increased by that cell's amount. Then I output that final value in the datagrid footer.
