If each row gets the same calculation preformed it may be wiser to perform the calculations in you select statement whe you get the data for the DataGrid. Add a calculation field to your select statement.

Otherwise you could possibly create a dataTable with the fields from the datagrid and a calculated field, loop through the grid and do the calculations, add the calculated field to the datatable, rebind the datagrid to the updated datatable.

I thought of that but the calculations are not so simple.They are inside a function witch reads not only the datagrid fields but also from the database from other tables.And also i want to perform the calculations when i press a button.I manage to put the results to textboxes but not in the datagrid for each row seperetly
