如何根据选中的复选框将列表返回给控制器？
我在剃刀视图中有一张数据表，我在表格中为每行添加了一个复选框。 我试图将检查的列表返回到控制器中的后置操作。 但是模型在帖子后面显示为空。
Model in view ..
@model IPagedList<TrackerModel>
在控制器中发布actionResult ....
[HttpPost]
public ActionResult Index(IList<TrackerModel> model)
{
return View(model);
}
表格标签在另一个表格中应用，因为表格在部分中。
<div id="all-calibrations-grid" class="pull-left tracker-container">
@using (Html.BeginForm(FormMethod.Post))
{
{Html.RenderAction("AllCalibrations");}
}
</div>
Tracker ViewModel ..
public class TrackerModel
{
public int Id { get; set; }
public string EquipmentID { get; set; }
public string EquipmentDescription { get; set; }
[DisplayFormat(DataFormatString = "{0:d}", ApplyFormatInEditMode = true)]
public DateTime? ExpectedReturnedToCustomer { get; set; }
[DisplayFormat(DataFormatString = "{0:d}", ApplyFormatInEditMode = true)]
public DateTime? DateOfCalibration { get; set; }
[DisplayFormat(DataFormatString = "{0:d}", ApplyFormatInEditMode = true)]
public DateTime? NextDueDate { get; set; }
public bool StatusChange { get; set; } //01/07/2014
public string Status { get; set; }
public string CustomerName { get; set; }
}
所有校准...
[RoleAuthorization(Roles = "Customer User Passive,LTS User Passive")]
public PartialViewResult AllCalibrations(int? page, IPrincipal user)
{
int totalRecords;
// the filter model is fully populated
var filter = (CalibrationFilter)Session["_Filter"];
filter.PageSize = ((CalibrationFilter)Session["_Filter"]).PageSize;
filter.Page = page.HasValue ? page.Value - 1 : 0;
IList<Calibration> calibrationList;
if (user.IsInRole("LTS User Passive"))
{
LtsUser ltsUser = _ltsUserRepo.GetUser(user.Identity.Name);
// access the required data from the calibration repository
calibrationList = _calRepo.GetAllCalibrations(ltsUser.Customers, out totalRecords, filter);
}
else
{
CustomerUser custUser = _custUserRepo.GetUser(user.Identity.Name);
var customer = new List<Customer> { _custRepo.GetCustomer(custUser.Customer.Name) };
// access the required data (for a specific customer) from the calibration repository
calibrationList = _calRepo.GetAllCalibrations(customer, out totalRecords, filter);
}
var customerViewList = Mapper.Map<IList<Calibration>, IList<TrackerModel>>(calibrationList);
IPagedList<TrackerModel> pagedList = customerViewList.ToPagedList(filter.Page, filter.PageSize, totalRecords);
return PartialView("AllCalibrations", pagedList);
}

如果我从post actionResult中删除IList，我只会得到第一个选定的模型。 我在做什么错？
我所做的是在视图中有一个隐藏的输入，它包含所选记录的列表，然后将其作为控制器操作的参数。
<input id="selectedRecords" name="selectedRecords" type="hidden" />
使用附加到复选框的javascript填充隐藏的输入，即在单击复选框时向隐藏的输入添加一个标识，然后在控制器操作上可以将其作为字符串访问; 我认为它甚至会自动在逗号之间插入逗号，使用类似于selectrow函数的东西，这些函数将循环通过网格并将选定的行ID放入隐藏的输入中。
$.each(checkedIds, function (value) {
// stuff
});
编辑：忘记每个循环，并阅读本示例如何获取选定的行数据然后获取该ID，并将其存储在隐藏的输入中，然后在控制器操作上发布后，您只需获取隐藏的输入值。
