asp.net - 如何将目标控件分配给服务器端的验证器控件

Question

我有 N 个动态生成的文本框。我想验证 Formate HH:MM:SS PM/AM 的每个文本框，所以我动态地创建验证控件。但由于动态文本框没有 ID，所以我必须将什么传递给 ControlToValidate 属性的验证控件？

手风琴窗格 ap1; for (int i = 0; i <= 2; i++) { ap1 = new AccordionPane(); ap1.HeaderContainer.Controls.Add(new LiteralControl("Using Markup")); 面板 pnl = 新面板（）；

                TextBox txtTime = new TextBox();
                txtTime.ID = "txtTimeBox" + i;
                txtTime.ValidationGroup = "MKE";
                RegularExpressionValidator validateDate = new RegularExpressionValidator();
                validateDate.ValidationExpression = "(0[1-9]|1[0-2]):([0-5][0-9]):([0-5][0-9]|60) (AM|PM|am|pm)";
                validateDate.ControlToValidate = txtTime.ID;
                validateDate.ErrorMessage = "Invalid Date. Try in HH:MM:SS AM/am|PM/pm format";

                pnl.Controls.Add(txtTime);
                ap1.ContentContainer.Controls.Add(pnl);
            MyAccordion.Panes.Add(ap1);
        }
        Page.Controls.Add(divContainer);
