ASP.NET部分視圖驗證失敗

Question

我在驗證我的局部視圖時遇到問題。 我的索引視圖由幾個局部視圖組成。 正在使用其中一種視圖_Contact，以便用戶可以提交即將發生的事件。 我想啟用檢查，是否有人已經使用輸入的電子郵件提交了活動。 一切正常，但問題是它不顯示有關提交失敗的消息（它在服務器端通過驗證失敗，但不會向用戶顯示錯誤）。 這是我的代碼：

 Index:
...
 @if(ViewBag.Competitor==null)
{@Html.Partial("_Contact", new CompetitorViewModel())}else
                          {
@Html.Partial("_Contact",(CompetitorViewModel)ViewBag.Competitor)
}
...

 _Contact:
 @model Models.CompetitorViewModel

 <script src="@Url.Content("~/Scripts/jquery.js")"></script>
 <script src="@Url.Content("~/Scripts/jquery.validate.min.js")"></script>
 <script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")">     </script>


<section id="contact">

家庭控制器：

    [HttpPost]
    public ActionResult SubmitStudent(CompetitorViewModel c)
    {
        var colleges = _db.colleges.Distinct().ToList();
        ViewBag.Colleges = new SelectList(colleges, "id", "Name"); 

             if (!ModelState.IsValid)
        {
            ViewBag.Competitor = c;

        }
        else
        {
            var competitors = _db.competitors;


            foreach (Competitor c1 in competitors)
            {
                if (c1.eMail == c.eMail)
                     {
                         ModelState.AddModelError("c.eMail", "That E-mail is already registered to this event.");
                         ViewBag.Competitor = c;
                         return View("Index");
                     }
            }


            DCCollege college = (DCCollege)_db.colleges.Find(c.collegeId);
            Competitor competitor = new Competitor();
            competitor.firstName = c.firstName;
            competitor.lastName = c.lastName;
            competitor.eMail = c.eMail;
            competitor.college = college;

            competitors.Add(competitor);
            _db.Save();
        }

        return View("Index");
    }

如果有人可以幫助我，我將不勝感激。 我為此苦了很長時間。

我迅速瀏覽了一下代碼。 我認為您看不到驗證消息，因為您將其添加到了ModelState，但是沒有將模型傳遞給視圖。
