Answer 1

I try this at bind time

  for (int n = 0; n < (dataGridView1.Rows.Count - 1); n++)
            {
                double i = Convert.ToDouble(dataGridView1.Rows[n].Cells["tamount"].Value.ToString().Replace('.', ','));
                double j = Convert.ToDouble(dataGridView1.Rows[n].Cells["paymentamount"].Value.ToString().Replace('.', ','));
                double total = i - j;
                if (total >= 1)
                {
                    dataGridView1.Rows[n].Cells["tamount"].Style.BackColor = Color.LightPink;
                    dataGridView1.Rows[n].Cells["paymentamount"].Style.BackColor = Color.LightPink;

                }
                else
                {
                    dataGridView1.Rows[n].Cells["tamount"].Style.BackColor = Color.LightGreen;
                    dataGridView1.Rows[n].Cells["paymentamount"].Style.BackColor = Color.LightGreen;
                }

            }
