Solution 1

An easy way would be to multiply the columns in SQL

SQL

SELECT field1, field2, field1 * field2 AS field3 
FROM sometable

Solution 2

You Can use loop

C#

for(int i = 0 ; i<datagrid.rows.count mode="hold" />
  {
        int a =datagrid.rows[i][0].value;
        int b =datagrid.rows[i][1].value;

        int c = a*b;

        c=datagrid.rows[i][2].value;


  }
