推荐答案

我遇到了同样的问题，刚才。

I ran into the same issue just now.

我解决它加入我参考了用户控件下方的CustomValidator，并通过公开，需要验证的属性验证从父用户控件。我反正公开这些属性，所以没什么大不了那里。

I solved it by adding a customvalidator beneath my reference to the usercontrol and validated the usercontrol from the parent by exposing the properties that required validation. I was exposing these properties anyway so no big deal there.

<div>
     <uc:MyChildUserControl ID="MyChildUserControl1" runat="server"></uc:MyChildUserControl >
     <asp:CustomValidator ID="MyChildUserControlCustomValidator" runat="server" ValidationGroup="default_validation" ErrorMessage="errormessage to show when the sh*t hit the fan" Text="*"></asp:CustomValidator>
</div>

和则的ServerValidate code：

And then the servervalidate code:

protected void MyChildUserControlCustomValidator_ServerValidate(object source, ServerValidateEventArgs args)
{
    args.IsValid = MyChildUserControl1.SomeProperty;
}
