you can calculate in textchange event of qty textbox and rate textbox and selectindex change of Tax combobox
for example for calculation,
if (txttax.SelectedIndex > 0)
            {
                try
                {
                        total = Convert.ToDouble(txtqty.Text) * Convert.ToDouble(qtytxtprice.Text);
                        tax = (Convert.ToDouble(txttax.SelectedValue) * total) / 100;
                        Totaltxt.Text = (total + tax).ToString();

                }
                catch { }
            }
