MVC验证不适用于局部视图

Question

我有一个包含用户创建表单的部分视图。当我使用@Html.Partial("_CreateUser")在主视图中调用该表单并尝试将其提交为空时，没有任何数据注释验证有效。但是，如果我将该部分视图单独返回给浏览器并再次尝试，则验证消息可以正常工作。任何建议，将不胜感激。代码如下。

视图模型

        [Required(ErrorMessage = "Please enter a first name.")]
        [Range(2,12, ErrorMessage = "First name must be between {1} and {2}   
        characters in length.")]
        [Display(Name = "First Name")]
        public string FirstName { get; set;  }

        [Required(ErrorMessage = "Please enter a last name.")]
        [Display(Name = "Last Name")]
        public string LastName { get; set; }

部分视图代码段

@using (Html.BeginForm("CreateUser", "OpsManagement"))
{
    @Html.AntiForgeryToken()
    @Html.ValidationSummary(true, "", new { @class = "text-danger" })

   <div class="form-group">
                    <div class="col-md-3">
                            <!--- First Name -->
                            @Html.LabelFor(model => model.FirstName, htmlAttributes: new { @class = "control-label" })
                            @Html.EditorFor(model => model.FirstName, new { htmlAttributes = new { @class = "form-control" } })
                            @Html.ValidationMessageFor(model => model.FirstName,"", new { @class = "text-danger" })
                    </div>

                    <div class="col-md-3">         
                            <!--- Last Name -->
                            @Html.LabelFor(model => model.LastName, htmlAttributes: new { @class = "control-label" })
                            @Html.EditorFor(model => model.LastName, new { htmlAttributes = new { @class = "form-control" } })
                            @Html.ValidationMessageFor(model => model.LastName, "", new { @class = "text-danger" })
                    </div>

  </div>
}
  @section Scripts {
    @Scripts.Render("~/bundles/jqueryval")
  }

主视图

<div id="newUserPartialView" class="collapse">
             @Html.Partial("_CreateUser")
          </div>
