Question

我正在开发一个使用ASP.NET MVC 5，C＃，Razor的解决方案。

问题：

我认为保存它后不会查看局部视图的内容，我只看到描述字段的文本框控件。

查看

@Html.HiddenFor(m=>m.Items)
@Html.Partial("~/Areas/Checks/Views/Shared/_ViewerItems.cshtml", Model.Items)

@Html.TextBoxFor(m => m.Description, new { @class = "form-control" })



@{
    var len = Request.RawUrl.Split('/').Count();
    var viewname = Request.RawUrl.Split('/')[len - 1];
    var _newprefixbuttoname = "Salva"+viewname;
    var _newprefixbuttonameProsegui = "Salva" + viewname+"Prosegui";
    //
    if (SessionManager.IsUserConnected(Xanta.ServiceLayer.BO.Ruoli.IsRole411))
    {
        <!-- saving buttons -->
        <div class="form-group">
            <div class="col-md-offset-2 col-md-10 text-right">
                <input type="submit" name="@_newprefixbuttoname" value="Salva" class="btn btn-lg btn-info" />
                <input type="submit" name="@_newprefixbuttonameProsegui" value="Salva e prosegui" class="btn btn-lg btn-success" />
            </div>
        </div>
    }


}

P.S。：使用的post方法与其他视图中使用的相同，但在这种情况下会出现此问题。无论如何，我向你展示

[HttpPost]
[ValidateAntiForgeryToken]
[HttpParamAction]
public ActionResult SaveData(Valutation mv)
{
    return savingDataValutation(mv);
}

private ActionResult savingDataValutation(Valutation mv, bool goon = false)
{
    if (!ModelState.IsValid)
        return View(mv);

    var responseData = manager.savingDataValutation(base.getCurrentCompany(), mv);
    if (responseData.Error)
        ModelState.AddModelError("", responseData.Message);

    if (goon)
        return RedirectToAction(nextpage);

    setSuccessMessage();
    return View(mv);
}

PartialView

@using System.Web.UI.WebControls
@model Xanta.Areas.Checks.ViewModels.ViewerVerificheViewModel
@{
    bool allrespnull = Model.Items.Count() == Model.Items.Count(x => x.RispostaValue == null);

        { 
              new ListItem { Text = "Bassa", Value = "B" }, 
              new ListItem { Text = "Medio Bassa", Value = "MB" } ,
              new ListItem { Text = "Medio Alta", Value = "MA" } ,
              new ListItem { Text = "Alta", Value = "A" } 
        };

partialview在其他环境中效果很好！但我不明白什么是错的。

有什么建议吗？感谢

最有可能是因为网络是无状态的，所以当您最初加载页面时（通过HTTPGET），您将所有项目加载到您的“mv＆＃39;”中。当您发布帖子（通过HTTPPOST）时，项目列表未与您的“mv”一起发布，因此您需要重新填充“mv＆＃39;”。返回视图前的项目。

为什么在ASP.NET MVC中的HttpPost Action之后看不到PartialView？
