asp.net-mvc - ASP.NET MVC : Redirecting from one view to another

Question

您好，我正在使用以下代码从剑道网格重定向到另一个页面( View ):

@(Html.Kendo().Grid<WM.ViewModels.StockReceiptsGridViewModel>()
    .Name("Grid")
    .ToolBar(toolbar => toolbar.Template("<a class='k-button k-button-icontext' onclick='addMaterialPopup()' href='#'></span>Create Stock Receipt</a>"))
    .Columns(columns =>
    {
        columns.Bound(p => p.StockReceiptID);
        columns.Bound(p => p.SupplierName);
        columns.Bound(p => p.Product);
        columns.Bound(p => p.Dimensions);
        columns.Bound(p => p.Quantity);
        columns.Bound(p => p.QuantityReserved);
        columns.Bound(p => p.PurchaseNumber);
        columns.Bound(p => p.Cost);
        columns.Bound(p => p.PhotosLink).Title("").ClientTemplate("<a href='/Photos/index?StockReceiptID=#=StockReceiptID#'>#=GetText()#</a>");
        columns.Command(command => command.Custom("Edit").Click("editreceipt"));

    })
    .DataSource(dataSource => dataSource
        .Ajax()
        .Batch(false)
        .Model(model => model.Id(p => p.StockReceiptID))
                    .Read(read => read.Action("Read", "StockReceiptsGrid").Data("ExtraData"))
  )
)

Javascript:

function editreceipt(e) {
    e.preventDefault();
    var dataItem = this.dataItem($(e.currentTarget).closest("tr"));
    var stockReceiptId = dataItem.StockReceiptID;

    window.location.href = "@Url.Action("Update","StockReceipt")"+"/"+stockReceiptId; // Problem code...

    }

StockReceipt Controller 上的接收方法是:

public ActionResult Update(int stockReceiptId)
{
   var stockReceipt = _stockReceiptRepository.GetAllStockReceipts().ToList().Where(r => r.StockReceiptID == stockReceiptId);

    var model = new StockReceiptViewModel();


    model.Notes = stockReceipt.First().Notes;



    return View("Index", model);
}

这是我的路线配置:

public static void RegisterRoutes(RouteCollection routes)
{
    routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

    routes.MapRoute(
        name: "Default",
        url: "{controller}/{action}/{id}",
        defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
    );
}

问题:

.. 上面的 Javascript 代码没有重定向，它带我到这个 URL:http://localhost:50439/StockReceipt/6

并报告“蓝屏死机”并出现以下错误:

参数字典包含“WorcesterMarble.Controllers.StockReceiptController”中方法“System.Web.Mvc.ActionResult Update(Int32)”的不可空类型“System.Int32”的参数“stockReceiptId”的空条目。可选参数必须是引用类型、可为 null 的类型，或者声明为可选参数。参数名称:参数

其中 6 是 ID。

如果我删除 id 元素，就会变成这样:

window.location.href = "@Url.Action("Update","StockReceipt")"

它可以工作，但我需要 ID，因为我想在目标 View 中加载选定的“ViewModel”。

我想知道我做错了什么？!

我尝试过使用这个，但没有成功:

window.location.href = @Url.RouteUrl("Default", new { @Controller = "StockReceipt", @Action = "Update"}) + '//' + stockReceiptId;

这样解决:

function editreceipt(e) {
    e.preventDefault();
    var dataItem = this.dataItem($(e.currentTarget).closest("tr"));
    var stockReceiptId = dataItem.StockReceiptID;

    window.location.href = "@Url.Action("Update","StockReceipt")?stockReceiptId=" + stockReceiptId; 
    }
