        TextBox txt_BCICU = (TextBox)grdlist.FindControl("txt_BCICU");
        TextBox txt_BCSupDlx = (TextBox)grdlist.FindControl("txt_BCSupDlx");
        txt_TotalChargeA.Text = (Convert.ToDecimal(txt_BCSupDlx.Text.Trim()) + Convert.ToDecimal(txt_BCICU.Text.Trim())).ToString();
 
protected void txt_BCICU_TextChanged(object sender, EventArgs e)
    {
        calculationA();
    }
 
protected void grdlist_RowUpdating(object sender, GridViewUpdateEventArgs e)
    {
        TextBox txt_BCICU = (TextBox)grdlist.Rows[e.RowIndex].FindControl("txt_BCICU");
