提交选中的行后没有获取任何值的操作

Question

使用的模型如下所示

 public class EmployeeAlconDetailsEditorViewModel
    {
        public int EMP_NO { get; set; }
        public string EMP_NAME { get; set; }
        public string EMP_ROLE_CODE { get; set; }
}



public class ListEmployeeAlconDetails
    {
        public List<EmployeeAlconDetailsEditorViewModel> listEmployee;
        public ListEmployeeAlconDetails() 
        {
            this.listEmployee = new List<EmployeeAlconDetailsEditorViewModel>();
        }
        public IEnumerable<EmployeeAlconDetailsEditorViewModel> getSelectedIds()
        {
            // Return an Enumerable containing the Id's of the selected people:
            return (from p in this.listEmployee where p.IsSelected select p).ToList();
        }


    }

通过此控制器显示视图，其中包含复选框。

 public ActionResult UploadAlconFile(HttpPostedFileBase UploadedFile)
        {
            if (UploadedFile != null && UploadedFile.ContentLength > 0)
            {



                List<TEMP_EMP_DETAILS_ALCON> listAdd = objTempAlcon.NewAlconDetails();
                var model = new ListEmployeeAlconDetails();
                foreach (TEMP_EMP_DETAILS_ALCON emp in listAdd)
                {
                    var alconDetails = new EmployeeAlconDetailsEditorViewModel()
                   {
                       IsSelected = true,
                       EMP_NO = emp.EMP_NO,
                       EMP_NAME = emp.EMP_NAME,

                   };
                    model.listEmployee.Add(alconDetails);
                }
                return View("AlconFileUploadView", model);
            }
            return View("AlconFileUploadView", null);
        }

显示表格的视图。

@model ALCONDashboardPortal.ViewModels.ListEmployeeAlconDetails



            @using (Html.BeginForm("PopUpSubmit", "ALCON", FormMethod.Post, new { encType = "multipart/form-data"}))
            {

            <div class="modal-header">
                <button class="close" aria-hidden="true" type="button" data-dismiss="modal">&times;</button>
                <h4 class="modal-title">Modal title</h4>
            </div>
            <div class="modal-body" id="modalContent">
   <table class="table table-condensed table-striped">

       @Html.EditorFor(model => model.listEmployee)
</table>

            </div>
            <div class="modal-footer">

                <button class="btn btn-default" type="button" data-dismiss="modal">Close</button>
                <input class="btn btn-primary" type="submit" name="submit" value="Save Changes" />
            </div>

EditorViewModel temlate

@model ALCONDashboardPortal.ViewModels.EmployeeAlconDetailsEditorViewModel

<tr>
    <td>
        @Html.CheckBoxFor(model => model.IsSelected)
    </td>
    <td>
        @Html.DisplayFor(model => model.EMP_NO)
    </td>
    <td>
        @Html.DisplayFor(model => model.EMP_NAME)
    </td>
</tr>

以下代码是提交表单后的操作。我正在获取模型对象但是计数为0，即表单提交后没有任何内容。

 public ActionResult PopUpSubmit(ListEmployeeAlconDetails model)
        {
            var selectedIds = model.getSelectedIds();
            // Use the ids to retrieve the records for the selected people
            // from the database:

            // Redirect somewhere meaningful (probably to somewhere showing 
            // the results of your processing):
            return RedirectToAction("Index");
        }
