我有一个Page水果，其中包含UpdatePanel P1和ModalWIndow（更新面板之外）。我有一个Page Apple，其中包含UpdatePanel P2。 ModalWindow水果上的Page会根据需要添加Page Apple。
现在，在Apple Page中
我有一个GridView EditItemTemplate和FooterItemtemplate，可以说5列。它们都有RegularExpressionValidator和RequiredFieldValidtor，每个ValidationGrou p分隔。对于EditItemTemplate来说，一切都是关键。
对于FooterItemTemplate，即使满足所有验证，该按钮也不会进行回发。
页脚模板对于感兴趣的列看起来像这样
<FooterTemplate>
<asp:TextBox ID="vendorAdd" runat="server" Width="95%"/>
<asp:RegularExpressionValidator ID="RegularExpressionValidator66" ControlToValidate="vendorAdd" ValidationGroup="AddValidation"
ValidationExpression="\w*" runat="server" ErrorMessage="Invalid VendorName" />
<asp:RequiredFieldValidator id = "RegularExpressionValidator67" ValidationGroup="AddValidation" ControlToValidate="vendorAdd"
runat="server" ErrorMessage="VendorName Required" />
</FooterTemplate>
没有消息称此失败。我删除了其他页脚列上的所有其他验证，而不是上面显示的。我在按钮上添加了停止验证。在服务器端添加了这个
Page.Validate("AddValidation");
var b = Page.IsValid;
var notValidValidators = Page.Validators.Cast<IValidator>().Where(v => !v.IsValid);`
调试器中notValidValidator表示RequiredFieldValidator无效。我不明白为什么，但我有一个价值，前端没有消息。
