My app is a sort of cash register for a shop so in the datagrid there is Reference ,
it is the reference of the product.
When the user types the reference directly the information about the product will be filled in the other columns and the user can choose the quantity he wants and it will do the calculation.

ALSO, I tried to put the total of the bill in the datagrid...

Reference | Product |Quantity |Price |Total |Total Bill
AB              |AB           |2               |1000 |2000 |5000
BC              |BC            |3              |1000 |3000

This is what I am trying to do... To do it, I tried this code:

private void TAB_Credit_RowValidated(object sender, DataGridViewCellEventArgs e)
{
    int sum = 0;
 
    for (int i = 0; i < TAB_Credit.Rows.Count; ++i)
    {
 
        sum += Convert.ToInt32(TAB_Credit.Rows[i].Cells["Total"].Value);
    }
 
    TAB_Credit.Rows[e.RowIndex].Cells["Total_Bill"].Value = sum.ToString();
}
