无法将选定行的MVC kendo网格的值传递给控制器

Question

我已经实现了kendo网格，右键单击上下文菜单以及当用户尝试选择上下文菜单时触发的select函数。当我选择编辑上下文菜单时，我试图传递某些列的值。我在客户端获取id和国家/地区代码，但我的控制器只获取id。不确定为什么国家代码会变为空。

网格

@(Html.Kendo().Grid<CC.GRP.MCRequest.ViewModels.RequestViewModel>()
.Name("GridRequest")
.Columns(columns => {
    columns.Bound(o => o.RequestID).Width("100px");
    columns.Bound(o => o.CountryCode).Width("100px");
    columns.Bound(o => o.SalesOffice).Width("100px");
    columns.Bound(o => o.CustomerNumber).Width("120px");
    columns.Bound(o => o.ProjectName).Width("120px");
    columns.Bound(o => o.ProjectContent).Width("120px");
    columns.Bound(o => o.ContractStartDate).Width("140px");
    columns.Bound(o => o.Priority).Width("120px");
    columns.Bound(o => o.NameOfResponsiblePerson).Width("170px");
    columns.Bound(o => o.Status).Width("100px");
    columns.Bound(o => o.CreatedBy).Width("110px");
    columns.Bound(o => o.CreatedDate).Width("110px");
    columns.Bound(o => o.ModifiedBy).Width("110px");
})
.Pageable()
.Sortable()
.Filterable()
.Scrollable()
.Groupable()

.Selectable(selectable => selectable
    .Mode(GridSelectionMode.Single)
    .Type(GridSelectionType.Row))
    .Events(events => events
    .Change("onChange")
)
.DataSource(dataSource => dataSource
    .Ajax()
    .Model(model => model.Id(t => t.RequestID))
        .Read(read => read.Action("Requests_Read", "Request"))
    )
)

上下文菜单

 @(Html.Kendo().ContextMenu()
        .Name("RequestMenu")
        .Target("#GridRequest")
        .Filter("tr")
        .Orientation(ContextMenuOrientation.Vertical)
        .Animation(animation =>
        {
            animation.Open(open =>
            {
                open.Fade(FadeDirection.In);
                open.Duration(500);
            });
        })
         .Items(items =>
         {
             items.Add()
                 .Text("Edit").HtmlAttributes(new { @class = "contextMenuItem" });

             items.Add()
                .Text("Update Status").HtmlAttributes(new { @class = "contextMenuItem" });

         })
         .Events(e =>
         {
             e.Select("onSelect");

         })
    )

的Javascript

function onSelect(e) {
        var grid = $("#GridTeam").data("kendoGrid");
        var requestId;

        switch ($(e.item).children(".k-link").text()) {

            case "Edit":
                var grid = $("#GridRequest").data("kendoGrid");
               // var column = grid.columns[0];
                var selectedBackup = grid.dataItem(grid.select());
                requestId = selectedBackup.id;
                code = selectedBackup.CountryCode;

                window.location.href = '@Url.Action("EditRequest", "Request", new { id = "_id_", status="Edit", countryCode = "_code_" })'.replace('_id_', requestId).replace('_code_', code);
                break;
            case "Update Status":

                var statusWindow = $("#window").data("kendoWindow");
                var grid = $("#GridRequest").data("kendoGrid");
                var selectedRow = grid.dataItem(grid.select()); 
                id = selectedRow.id;
                name = selectedRow.ProjectName;
                code = selectedRow.CountryCode;
                statusWindow.refresh({ data: { requestId: id, projectName: name, countryCode: code } }).center().open();
        }
    }

控制器

 [Route("Request/AddRequest")]
        [Route("Request/EditRequest/{id?}")]
        public ActionResult NewRequest_Read(string id, string countryCode)
        {
            NewRequestViewModel newReqeustViewModel = new NewRequestViewModel();

            if (!string.IsNullOrEmpty(id))
            {
                var result = requestRepository.GetRequesById(int.Parse(id));
                return View("NewRequestView", (Mapper.Map<NewRequestViewModel>(result)));
            }
            return View("NewRequestView", newReqeustViewModel);
        }

routedebugger输出

route.config

        routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
