@yesubabu Well it was just an idea to get the tax amount quickly. I assume that DataTable has been used to bind the gridview. var dt = new DataTable (); // assuming having rows and bind with gridview var sumFirst = Convert.ToDouble (dt.Compute ( Sum (vat)  [vat(%)] = 14.5 )); var sumSecond = Convert.ToDouble (dt.Compute ( Sum (vat)  [vat(%)] = 5.0 )); // display your outputs as required Hope you got an idea to implement this.

Hi Yesubabu Its simple Try this code private void Form3_Load( object sender EventArgs e) { myDataGridView.Rows.Add(); myDataGridView.Rows.Add(); myDataGridView.Rows[0].Cells[0].Value = 1; myDataGridView.Rows[0].Cells[1].Value = Ice Cream ; myDataGridView.Rows[0].Cells[2].Value = 14.50; myDataGridView.Rows[1].Cells[0].Value = 1; myDataGridView.Rows[1].Cells[1].Value = Cone ; myDataGridView.Rows[1].Cells[2].Value = 5.0; } rivate void button1_Click( object sender EventArgs e) { decimal sum = 0; for ( int i=0;i { sum = sum + Convert.ToDecimal(myDataGridView.Rows[i].Cells[2].Value); } MessageBox.Show(myDataGridView.Rows.Count.ToString()); myDataGridView.Rows[2].Cells[2].Value = sum; }
