Asp.net mvc Telerik dropdownlist不'；t在网格类库中加载

我必须创建一个nopCommerce插件来实现一些telerik网格，其中dropdownlist作为可编辑行，问题是该插件是一个类库，而不是ASP.NET MVC应用程序，路由是在RouteProvider.cs文件中手动完成的。所以我在这里引用了这个例子： 并且必须具有以下配置： 我的模型：

    public class ContentModel : BaseNopModel
{
    public string ContentId { get; set; }

    [NopResourceDisplayName("Plugins.Widgets.DiscountBanner.Title")]
    public string Title { get; set; }

    [NopResourceDisplayName("Plugins.Widgets.DiscountBanner.Content")]
    public string Content { get; set; }

    [UIHint("DiscountsEditor"), Required]
    public string Discounts { get; set; }
}

我的控制器：

[GridAction]
public ActionResult _SelectAjaxEditing()
{
    List<ContentModel> model = new List<ContentModel>();
    return View("Nop.Plugin.Widgets.DiscountBanner.Views.WidgetsDiscountBanner.Configure", _discountBannerSettings.contentGrid == "" || _discountBannerSettings.contentGrid == null ? new GridModel(model) : new GridModel(JsonHelper.JsonDeserialize<List<ContentModel>>(_discountBannerSettings.contentGrid)));
}

但是模板在我将一些信息放入网格后加载，不可编辑，如果我想编辑它，dropdownlist会转换为文本框，我不知道下一步该怎么做，或者我是否可以使用另一个控制器，但可以从当前视图而不是部分视图加载下拉列表

谢谢。

您需要将视图复制到输出目录。尝试将其更改为“更新时复制”。您还需要在视图文件夹中添加一个web.config文件
