Ok after your comment i just recommend that you use .ToList() to help grid to recognise the data source :

 int id = int.Parse(dgvTable.Rows[dgvTable.CurrentRow.Index].Cells[0].Value.ToString());
 var values = (from c in v.db.TotalDoc
               where c.TotalID == id
               select c.TotalAmount).ToList();
 dgvValues.DataSource = values;
