【问题描述】：

我正在用 ActionLink 做一些疯狂的事情。它工作一次，然后不会再次更新 DIV。当我调试它时，代码会遍历所有内容，但更改不会出现在 DIV 中。

@Ajax.ActionLink("Make/Model", "SortVehicle", "Exposure", new { an = agreementNumber, sortOrder = "make" }, new AjaxOptions() { UpdateTargetId = "VehicleScheduleEdit", InsertionMode=InsertionMode.Replace })

控制器代码：

   public ActionResult SortVehicle(int an, string sortOrder)
    {
        switch (sortOrder)
        {
            case "year":
                sortOrder = "VehicleSchedule.AutoYear";
                break;
            case "make":
                sortOrder = "VehicleSchedule.MakeModel";
                break;
           default:
                sortOrder = "VehicleSchedule.MakeModel";
                break;
        }
        VehicleScheduleViewModel objVehicleModel = new VehicleScheduleViewModel();

        ViewData["VehicleScheduleViewModel"] = objVehicleModel.GetVehicleScheduleSorted(an, sortOrder);
        return PartialView("_VehicleSchedule");

    }

获取数据：

public IEnumerable<VehicleScheduleViewModel> GetVehicleScheduleSorted(int agreementNumber, string sortOrder)
{
    var dataVehicle = (from VehicleSchedule in trustDB.LicensedAutos
            where VehicleSchedule.AgreementNumber == agreementNumber
            orderby (sortOrder)
            select new VehicleScheduleViewModel
            {
                RID = VehicleSchedule.RID,
                MakeModel = VehicleSchedule.MakeModel,
                IDNumber = VehicleSchedule.IDNumber,
                Location = VehicleSchedule.Location,
                AutoYear = VehicleSchedule.AutoYear,
                AutoValue = (double?)VehicleSchedule.AutoValue ?? 0,
                YearAddedtoDistrict = (DateTime?)VehicleSchedule.YearAddedtoDistrict ?? DateTime.Now,
                NumOfPassengers = (int?)VehicleSchedule.NumOfPassengers ?? 0,
                DistVehNo = VehicleSchedule.DistVehNo,
                NoCollision = VehicleSchedule.NoCollision,
                NoComp = VehicleSchedule.NoComp,
                InvalidVIN = VehicleSchedule.InvalidVIN,
                AgreementNumber = (float?)VehicleSchedule.AgreementNumber ?? 0
            });

    return dataVehicle;
}

【解决方案1】：

您必须确保您的 UpdateTargetId = VehicleScheduleEdit 指向您要更新的 div 元素的适当 ID。

您还需要确保您的 PartialView 放置在此 div 元素中，而不是 div 元素是您的 PartialView 的一部分。
