    dataGridView1.Columns[1].Name = "Price";
    dataGridView1.Columns[2].Name = "Quantity";
    dataGridView1.Columns[3].Name = "Sub-Total";
     
    //Set a value to be added in a row

private void dataGridView1_CellClick(object sender, DataGridViewCellEventArgs e)
{
    DataGridView dtg = new DataGridView();
    dtg = dataGridView1;
 
    txtProduct.Text = dtg.CurrentRow.Cells[0].Value.ToString();
    txtPrice.Text = dtg.CurrentRow.Cells[1].Value.ToString();
    txtQauntity.Text = dtg.CurrentRow.Cells[2].Value.ToString();
    txtSubtotal.Text = dtg.CurrentRow.Cells[3].Value.ToString();
}
