Question

我现在非常沮丧，这应该很容易做到，而且我尝试了很多不同的方法来做到这一点，但是由于某种原因，我似乎无法展示我的需要。我已经为此工作了几个小时，通常只是它

@if (ViewBag.NextPartNumber != null) {  @ViewBag.NextPartNumber }

或

@Html.EditorFor(x => x.PartNextNumber, new { htmlAttributes =
                                         new { @class="Form-control", @Value = Model.PartNextNumber }})

I在Dropdownlist中选择一个选项，然后在选择该选项时会相应显示。不知道为什么这些都不起作用，但是我在视图中有一个Model，并且在将其传递给视图时，该属性在Debug中已正确设置。我还尝试设置Viewbag而不是我会满意的以太方式。这是我的代码，一堆我一直在尝试以任何方式显示它的ID感到满意。

控制器（如果您想让我的方法显示如何获得此信息，可以添加它，但请在此处更正）

public ActionResult TakeOutPart()
    {
        CreatePartBookSelectList();
        CreateEnteredBySelectList();
        CreateSoftwareTypeSelectList();

        CreateManufacturerSelectList();
        CreateDescriptionSelectList();
        CreateUsageSelectList();
        CreateUnitsSelectList();
       // CreateMachineTypeSelectList();
        var model = new PartNumberViewModel();
        model.ListMachTypes = GetMachineTypes();

        return View(model);
    }
    //[HttpPost, ActionName("TakeOutPart")]
    public ActionResult TakeOutPartVM(PartNumberViewModel model)

                                </div>

仅在只读文本框MVC 5中显示属性或视图包
