在web.config中启用时，客户端验证不起作用

Question

我正在使用.NET MVC 5构建网站。

我有一个包含以下内容的ViewModel

public class ContactPageModel
{
    public string Selection{ get; set; }
    public string MonthlyCost { get; set; }

    public ContactInfo Contact { get; set; }
}

我的数据注释位于ContactInfo

中

public class ContactInfo
{
    [Display(Name = "First Name: ")]
    [Required(ErrorMessage = "First Name Required")]
    public string FirstName { get; set; }

    [Display(Name = "Last Name: ")]
    [Required(ErrorMessage = "Last Name Required")]
    public string LastName { get; set; }

    [Display(Name = "State: ")]
    [Required(ErrorMessage = "State Required")]
    public string State { get; set; }

    [Display(Name = "Phone Number: ")]
    [Required(ErrorMessage = "Phone Number Required")]
    public string Phone { get; set; }

    [Display(Name = "Email: ")]
    [Required(ErrorMessage = "Email Required")]
    public string Email { get; set; }

    [Display(Name = "Best Contact Time: ")]
    [Required(ErrorMessage = "Best Contact Time Required")]
    public string BestContractTime { get; set; }
}

如何正确设置数据注释，以便视图正确使用它们？

以下是我的一些观看代码：

    <div class="form-group">
        @Html.LabelFor(model => model.Contact.LastName, htmlAttributes: new { @class = "control-label col-md-2" })
        <div class="col-md-10">
            @Html.EditorFor(model => model.Contact.LastName, new { htmlAttributes = new { @class = "form-control" } })
            @Html.ValidationMessageFor(model => model.Contact.LastName, "", new { @class = "text-danger" })
        </div>
    </div>

我确实通过web.config中的ClientValidationEnabled和UnobtrusiveJavaScriptEnabled键启用了客户端验证。

我没有得到验证消息。我假设这是因为我有ContactInfo类与ContactPageModel类嵌套。
