带有模型错误的Ajax表单

Question

我在mvc 4中创建了一个Ajax表单，就像那样

      @using (Ajax.BeginForm("Create", ajaxOptions: new AjaxOptions { UpdateTargetId = "updatedDiv", OnFailure = "OnFailure" }))
    {

        @Html.AntiForgeryToken()
        @Html.ValidationSummary()
        <div id="Errors" class="block">
        </div>

@*<div class="block width-50">
            <div class="input-group" style="direction: ltr">
                <input type="text" class="form-control">
                <span class="input-group-addon">Incoming No</span>
            </div>
        </div>*@

        <div class="block" id="item-guarantee">
            @Html.RadioButtonFor(m => m.CorrespondenceSideId, 1, new { @checked = "checked" })<label class="label-style">@Global.CorrespondenceSide_Internal</label>
            @Html.RadioButtonFor(m => m.CorrespondenceSideId, 2)<label class="label-style">@Global.CorrespondenceSide_External</label>
            @Html.ValidationMessageFor(m => m.CorrespondenceSideId)
        </div>
        <div class="block">
            <div class="input-group">
                @Html.Label(Global.Correspondence_CorrespondenceNo)
                @Html.EditorFor(m => m.CorrespondenceNo)
                @Html.ValidationMessageFor(m => m.CorrespondenceNo)
            </div>
        </div>

        <div class="block">
            <div class="input-group">
                @Html.Label(Global.Correspondence_IncomingNo)
                @Html.EditorFor(m => m.IncomingNo)
                @Html.ValidationMessageFor(m => m.IncomingNo)
            </div>

        </div>
}

这是控制器

 public ActionResult Create(Correspondence model)
{
    ViewBag.BoxType = (Enum_BoxType)model.BoxTypeId;

    ViewBag.CorrespondenceTypesList = this.Factory.Get<CorrespondenceTypesService>()
                                                  .GetAsListItems(this.CurrentLanguage);
    ViewBag.AssignmentSidesList = this.Factory.Get<AssignmentSidesService>()
                                              .GetAsListItems(this.CurrentLanguage);
    ViewBag.IncomingSidesList = this.Factory.Get<IncomingSidesService>()
                                            .GetAsListItems(this.CurrentLanguage);

    ViewBag.Lookup_BoxTypes = this.Factory.Get<BoxTypesServices>().GetAsListItems(this.CurrentLanguage, (int)ViewBag.BoxType);

    if (!ModelState.IsValid)  return PartialView("_CreatePartial", model); 

    this.Factory.Get<CorrespondencesService>().AuthorizedAdd(model);

    var AllCorrespondences = this.Factory.Get<CorrespondencesService>().GetAll(correspondence => correspondence.Date, (Enum_BoxType)model.BoxTypeId).ToList();
    return new View("Index", AllCorrespondences.ToPagedList(1, 5));
}

现在，当我返回PartialView("_CreatePartial", model);并且模型返回时出现模型错误时，错误不会出现在＆＃39; validationsummary（）＆＃39;在部分
