EnumDropDownListFor不绑定到绑定模型

Question

我正在使用EnumDropDownListFor，但它没有将值传输到Binding模型。 CourseId和StudentId到达绑定模型，但不到达枚举值。

感谢您的帮助!!

这是我的观点：

@model IEnumerable<LeisureTimeSystem.Models.ViewModels.Course.CourseApplicationViewModel>
<table class="table">
<tr>
    <th>
        @Html.DisplayNameFor(model => model.FirstOrDefault().Student.Name)
    </th>
    <th>
        @Html.DisplayNameFor(model => model.FirstOrDefault().Student.Username)
    </th>
    <th>
        @Html.DisplayNameFor(model => model.FirstOrDefault().Student.Email)
    </th>
    <th></th>
</tr>

@foreach (var item in Model)
{
    using (Html.BeginForm())
    {
        @Html.Hidden("CourseId", item.Course.Id)
        @Html.Hidden("StudentId", item.Student.Id)

        <tr>
            <td>
                @Html.DisplayFor(model => item.Student.Name)
            </td>
            <td>
                @Html.DisplayFor(model => item.Student.Username)
            </td>
            <td>
            @Html.DisplayFor(model => item.Student.Email)
            <td>

            @Html.DisplayFor(model => item.Status)
            </td>

            @Html.EnumDropDownListFor(model => item.Status, "Change Status", new { @class = "form-control" })
            <div class="form-group">
                <input type="submit">
            </div>
        </tr>
    }
}

</table>

这是我的观点模型：

public class CourseApplicationViewModel
{
    public ApplicationCourseViewModel Course { get; set; }

    public ApplicationStudentViewModel Student { get; set; }

    public ApplicationStatus Status { get; set; }
}

这是我的Binding模型：

public class ChangeStatusApplicationBindingModel
{
    public int StudentId { get; set; }

    public int CourseId { get; set; }

    public ApplicationStatus Status { get; set; }
}

这是Controller的行动：

[HttpPost]
public ActionResult ManageCourseApplications(ChangeStatusApplicationBindingModel model)
{
    if (this.ModelState.IsValid)
    {
        this.service.ChangeStatus(model);
        return RedirectToAction("ManageCourseApplications", new { studentId = model.StudentId, courseId = model.CourseId });
    }

    var changeStatusViewModel = this.service.GetAllCourseApplicationViewModels(model.CourseId);

    return this.PartialView(changeStatusViewModel);
}

枚举：

public enum ApplicationStatus
{
    AwaitingConfirmation,
    Approved,
    Denied
}

HTML：

＆＃13;

＆＃13;

<div class="container body-content">
    


<h2>Shakespeare Applications</h2>

<p>
    <a href="/Course/Create">Create New</a>
</p>

    <select class="form-control" data-val="true" data-val-required="The Status field is required." id="item_Status" name="item.Status"><option value="">Change Status</option>
<option selected="selected" value="0">AwaitingConfirmation</option>
<option value="1">Approved</option>
<option value="2">Denied</option>
</select><div class="form-group">
                    <input type="submit">
                </div><table class="table">
    <tbody><tr>
        <th>
            Name
        </th>
        <th>
            Username
        </th>
        <th>
            Email
        </th>
        <th></th>
    </tr>

<form action="/Course/ManageCourseApplications?courseId=4" method="post"></form><input id="CourseId" name="CourseId" type="hidden" value="4"><input id="StudentId" name="StudentId" type="hidden" value="1">            <tr>
                <td>
                    Secondsdasa
                </td>
                <td>
                    TheBest
                </td>
                <td>
                    <a href="mailto:"></a>
                </td><td>

                    AwaitingConfirmation
                </td>

                
    
            </tr>

    </tbody></table>
