                      decimal Quantity = Convert.ToDecimal(dataGridView1.Rows[i].Cells[2].Value);
                      decimal Rate = Convert.ToDecimal(dataGridView1.Rows[i].Cells[3].Value);
                      decimal vat = Convert.ToDecimal(dataGridView1.Rows[i].Cells[4].Value);

                      decimal TotalPrice = Convert.ToInt32(Quantity * Rate);

                      decimal TempVatTax = TotalPrice * Convert.ToDecimal(dataGridView1.Rows[i].Cells[4].Value) / 100;

                      TotalPrice = TempVatTax + TotalPrice;
                      dataGridView1.Rows[i].Cells[5].Value = TotalPrice;


                      Final = Convert.ToDouble(TotalPrice);
                      //Final=Convert.ToDouble(txt_Total.Text+Final);
                      //Final += CInt(row.Cells(0).Text);

                      txt_Total.Text = Convert.ToString(Final);

              }

Solution 1

I assume you are using this in a loop, from the Rows[i] stuff? If so, then if you want Final to be a cumulative total, then replace "=" with "+=":

C#

Final = Convert.ToDouble(TotalPrice);

Becomes

C#

Final += Convert.ToDouble(TotalPrice);

C#

double LastTotal=0;
           double Final = 0;
                     //decimal Serial = Convert.ToInt32(dataGridView1.Rows[i].Cells[0].Value);
                     decimal Quantity = Convert.ToDecimal(dataGridView1.Rows[i].Cells[0].Value);
                     decimal Rate = Convert.ToDecimal(dataGridView1.Rows[i].Cells[1].Value);
                     decimal vat = Convert.ToDecimal(dataGridView1.Rows[i].Cells[2].Value);

                     decimal TotalPrice = Convert.ToInt32(Quantity * Rate);

                     decimal TempVatTax = TotalPrice * Convert.ToDecimal(dataGridView1.Rows[i].Cells[3].Value) / 100;

                     TotalPrice = TempVatTax  + TotalPrice;

                     dataGridView1.Rows[i].Cells[4].Value = TotalPrice;


                     Final = Convert.ToDouble(TotalPrice);
           //Add this Code to your COde Editor
                     if (txt_Total.Text != "")
                     {
                         LastTotal = Convert.ToDouble(txt_Total.Text);
                     }
                     txt_Total.Text = Convert.ToString(Final+LastTotal);
