我正在验证日期输入服务器端并添加ModelError用户输入是否无效。以下是我的代码

public ActionResult EditOffer()
    {
        var offerID = Convert.ToInt64(Request.RequestContext.RouteData.Values["id"]);
        using (joyryde_storeEntities context = new joyryde_storeEntities())
        {
            var objOffer = context.tbl_offer.Where(x => x.LNG_OFFER_ID == offerID).FirstOrDefault();
            ViewBag.OfferID = offerID;
            ViewBag.Header = "Edit " + objOffer.TXT_OFFER_TITLE;
            ViewBag.ActionToPerform = "Edit";
            if (System.IO.File.Exists(Server.MapPath(string.Format("~/assets/images/Stores/{0}/O_{1}_Small.jpg", Session["StoreID"], offerID))))
            {
                objOffer.TXT_OFFER_SMALL_PATH = string.Format("~/assets/images/Stores/{0}/O_{1}_Small.jpg", Session["StoreID"], offerID);
            }
            return View("AddOffer", objOffer);
        }       
    }
    [HttpPost]
    public ActionResult EditOffer(tbl_offer modal, string Add, string Edit)
    {
        if (ModelState.IsValid)
        {
            using (joyryde_storeEntities context = new joyryde_storeEntities())
            {
                var offerID = Convert.ToInt64(Request.RequestContext.RouteData.Values["id"]);
                if (!isOfferExist(modal.DAT_START_OFFER.Value.Date, modal.DAT_END_OFFER.Value.Date.AddHours(23).AddMinutes(59).AddSeconds(59).AddMilliseconds(999), Convert.ToInt64(Session["StoreID"]), offerID, Add, Edit, context))
                {
                    // My Code 
                    return RedirectToAction("AllOffers", "Store");
                }
                else
                {
                    ModelState.AddModelError("DAT_START_OFFER", "Date Not Available"); // Here i am adding Modal Error For Date
                    if (Edit != null)
                    {
                        return RedirectToAction("EditOffer");
                    }
                    else
                    {
                        return RedirectToAction("AddOffer");
                    }
                }

            }

        }
        else
        {

            return RedirectToAction("EditOffer");
        }

    </div>
</div>

但是模态错误没有显示在视图中。可能是什么原因 ？

当您设置模型错误时，您使用 RedirectToAction，这意味着您加载新页面，检查您的调试，然后您的代码返回 GET 方法并重新加载所有内容。你必须用模型返回你的视图。

ModelState.AddModelError("DAT_START_OFFER", "Date Not Available");
if (Edit != null)
{
    return View(modal); //if your model is object named modal
}

如果您使用return RedirectToAction("EditOffer");错误将不被显示，它将被重定向到public ActionResult EditOffer(){}Action 方法，[HttpGet]将被显示。
要纠正这个错误，你应该使用View()方法。喜欢return View();它将错误返回到表单数据发布页面。

    [HttpPost]
public ActionResult EditOffer(tbl_offer modal, string Add, string Edit)
{
    if (ModelState.IsValid)
    {
        using (joyryde_storeEntities context = new joyryde_storeEntities())
        {
            var offerID = Convert.ToInt64(Request.RequestContext.RouteData.Values["id"]);
            if (!isOfferExist(modal.DAT_START_OFFER.Value.Date, modal.DAT_END_OFFER.Value.Date.AddHours(23).AddMinutes(59).AddSeconds(59).AddMilliseconds(999), Convert.ToInt64(Session["StoreID"]), offerID, Add, Edit, context))
            {
                // My Code 
                return RedirectToAction("AllOffers", "Store");
            }
            else
            {
                ModelState.AddModelError("DAT_START_OFFER", "Date Not Available"); // Here i am adding Modal Error For Date
                if (Edit != null)
                {
                    return View(modal);
                }
                else
                {
                    return RedirectToAction("AddOffer");
                }
            }

        }
    }
    else
    {
        ViewBag.OfferID = Here give the office id;
        ViewBag.Header = "Edit " + objOffer.TXT_OFFER_TITLE;
        ViewBag.ActionToPerform = "Edit";
        ModelState.AddModelError("","Your Error Message"); // Here i am adding Modal Error For Date
        return View(modal);
    }
}

由于 RedirectToAction，您没有看到任何错误。您应该使用“查看”方法。例如你可以写return EditOffer()
