Hello

If you want to have a sum column:
I prefer to create a new property in my class named Sum
If you can modify the database Alter the table or the view create a new Sum Column (Computed Column)
http://msdn.microsoft.com/en-us/library/ms191250.aspx[^]
But if you can't modify the database, then you can make it's class manually.

If you want to display Sum Total in the Footer of the GridView Control:

you can show the total at the footer of the gridview.

use footeritemitemplate and handle the rowdatabound event of gridview.

Solution 3

Sum your needed value

C#

int sum = 0;
foreach(DataGridViewRow item in grid.Rows)
{
   sum += item.Cells[INDEX_YOUR_VALUE].Value;
}

Add a last row with the sum value

C#

grid.Rows.Add(YOUR_PARAMETERS_BEFORE, sum);

Is this what you are looking for?
Regards.
