我已经创建了一个用户控件并在其中使用了组验证，但我是组验证的新手，我知道必填字段是如何工作的，但在验证组中，我无法使用我自己的必需的归档验证器。有一些自定义验证器使用javascript在客户端工作。请指导我如何使用自定义验证器，验证组和javascript的组合来使用js显示错误消息

您还必须在按钮中提及ValidationGroup
<asp:Button ID="Button2" runat="server" Style="display: none" Text="Button" ValidationGroup="G1" />
例如，当您必须在提交按钮中验证某些内容时，单击将相同的组分配给您提交的控件。
