winforms - 如何访问行以访问 XtraGrid CardView DevExpress 中的记录

Question

我有一个设置了主从关系的网格控件，但是我想知道如何访问详细视图记录或行以执行编辑或更新信息。我已经尝试过了，但它不起作用，它返回 0 到表单：

void AddPayment_Click(object sender, EventArgs e) {
    Paymentfrm payent = new Paymentfrm(Utils.Formtype.add, 0);
    payent.PaymentEvent += new EventHandler(RefreshingGrid);
    payent.PayentlabelsEvent += new EventHandler(RefresHlabels);

    gridView1.ViewCaption = " Lessee Payment ";
    CardView card = new CardView(DgPaymentYW);
    DgPaymentYW.LevelTree.Nodes.Add("LesseePayments", card);

    card.ViewCaption = " Lessee Payments";
    GetPayment.TotalPrice = Convert.ToDecimal(card.GetFocusedRowCellValue("TotalPrice"));


    payent.ShowDialog();
}
