网格视图验证
本文关键字：验证 视图 网格 | 更新日期: 2023-09-27 17:56:46
我正在使用网格视图并使用项模板文本框。有 5 个文本框，我在单击添加行 btn 时动态添加新行。在该行中，我添加了所有空的文本框。现在我想在 btn 上验证该文本框，单击下一步。
现在开始做？
我使用必填字段验证它第一次显示文本框，但是当我添加新的行文本框时，它不会导致验证，我认为还有其他方法可以为动态添加的文本框进行验证。
如何验证所有动态添加的文本框
我正在使用的网格视图..

您已在"下一步"按钮上使用验证组的ValidationGroup="a"，但尚未在必填字段验证器上使用该。但是您已经在电子邮件验证器中使用了它。
您必须与验证控件保持一致，以及是否对所有控件和按钮控件进行验证才能使其正常工作。
<asp:Button ID="btnNext" runat="server" ValidationGroup="a" CausesValidation="true" Text="Next" class="next btn" onclick="btnNext_Click"/>
我认为您应该开始一个新页面并使用更小的案例场景进行测试，并首先使其正常工作。 然后添加更多框。
如果您仍然需要有关该较小页面的帮助，请发布它以寻求帮助 - 我们将更容易理解它。
