我想显示错误消息。

ShowSummary="false" EnableClientScript="false"/>
      </div>

验证摘要不显示在网格视图中

我认为这就是问题所在，请将此属性设置为true

  EnableClientScript="true"

更新：遇到问题，是validationGroup，请将validationGroup属性添加到validationSummary或从RequiredFieldValidators 中删除validationGroup

<asp:ValidationSummary runat="server"  ID="update" DisplayMode="BulletList" ValidationGroup="update"/>
<asp:ValidationSummary runat="server"  ID="save" DisplayMode="BulletList" ValidationGroup="save"/>

我建议您使用验证组。此外，为EditItemTemplate验证器和Footer验证器创建单独的ValidationGroup。这将防止一个发射另一个。此参考资料也将帮助您：

参考：验证组

尝试将ShowSummary设置为"true"或ShowMessageBox设置为"true"
