asp.net-mvc-2 - Telerik Grid for ASP.NET MVC2 Ajax 绑定(bind)不起作用/路由到错误的操作

Question

网格加载服务器绑定(bind)的 b/c。
所有其他操作要么发布到错误的路线，要么发布到默认操作:
将帖子插入/EditOrder 操作
将帖子编辑为
这个地址:
http://localhost:20588/Orders/EditOrder/sdsddd?OrderID=2&CustomerID=1&ItemsInOrderGrid-mode=edit
这是没有意义的(sdsddd 是 ItemID)
没有到达 Controller 中 AJAX 部分内的断点。
知道我在做什么错吗？

谢谢，

这是查看代码:

 <%=
                Html.Telerik().Grid(Model.ItemsInOrderList)
                    .Name("ItemsInOrderGrid")
                                    .DataKeys(dataKeys =>
                                    {
                                        dataKeys.Add(e => e.OrderID);
                                        dataKeys.Add(e => e.ItemID);
                                    })
                    .ToolBar(commands => commands.Insert())
                    .DataBinding(dataBinding =>
                        dataBinding.Ajax()    //Ajax binding
                .Select("ItemsGridAjax", "Orders", new {OrderID = Model.order.OrderID})
                .Insert("InsertItemsGridAjax", "Orders", new {OrderID = Model.order.OrderID})
                .Update("UpdateItemsGridAjax", "Orders")
                .Delete("DeleteItemsGridAjax", "Orders"))
                    //.BindTo(Model.ItemsInOrderList)
                    .Columns(c =>
                        {
                            c.Bound(o => o.ItemID);
                            c.Bound(o => o.OrderID).Column.Visible = false;
                            c.Bound(o => o.ItemDescription);
                            c.Bound(o => o.NumOfItems);
                            c.Bound(o => o.CostOfItem);
                            c.Bound(o => o.TotalCost);
                            c.Bound(o => o.SupplyDate);
                            c.Command(commands =>
                                {
                                    commands.Edit();
                                    commands.Delete();
                                }).Width(200);
                        })

            %>

这是 Controller 中的代码:

[GridAction]    
public ActionResult ItemsGridAjax(int OrderID)       
{          
return View(ordersRepository.GetOrderItemsTK(OrderID));     
}

[HttpPost]
        [GridAction]
        public ActionResult InsertItemdGridAjax(int OrderID)
        {
            //Create a new instance of the EditableCustomer class.
            ItemsInOrder newItem = ItemsInOrder.CreateItemsInOrder(OrderID, "");
            newItem.OrderID = OrderID;

            //Perform model binding (fill the customer properties and validate it).
            if (TryUpdateModel(newItem))
            {
                //The model is valid - insert the customer.
                bool res = ordersRepository.InsertItemToOrder(OrderID, newItem);
            }

            //Rebind the grid
            return View(ordersRepository.GetOrderItemsTK(OrderID));
        }



[HttpPost]
  [GridAction]
  public ActionResult UpdateItemsGridAjax(int OrderID, string ItemID)
  {
      //Find a customer whose CustomerID is equal to the id action parameter
      ItemsInOrder item = ordersRepository.FindItemByID(OrderID,ItemID);

      if (item != null)
      {
          //Perform model binding (fill the customer properties and validate it).
          if (TryUpdateModel(item))
          {
              //The model is valid - update the customer and redisplay the grid.
              ordersRepository.UpdateItem(item);
          }
      }
      // TODO: Add try-catch with error reporting.
      //Rebind the grid
      return View(ordersRepository.GetOrderItemsTK(OrderID));
  }

[HttpPost]
        [GridAction]
        public ActionResult DeleteItemsGridAjax(int OrderID, string ItemID)
        {
            //Find the customer with the specified id
            ItemsInOrder item = ordersRepository.FindItemByID(OrderID, ItemID);

            if (item != null)
            {
                //Delete the customer
                ordersRepository.DeleteItem(item);
            }

            //Rebind the grid
            return View(ordersRepository.GetOrderItemsTK(OrderID));
        }

我不确定您是否需要 [HttpPost]属性(我认为 [GridAction] 就足够了)在那些 Ajax 操作上，也许尝试删除这些，看看是否能解决问题。

如果这不起作用，请尝试返回 GridModel在你的行动中:

        [GridAction]
        public ActionResult InsertItemdGridAjax(int OrderID)
        {
            //Omitted Code

           return View(new GridModel(ordersRepository.GetOrderItemsTK(OrderID)));
        }

您还可以使用类似于以下的语法(因为我认为 GridModel 喜欢拥有 total ):

        [GridAction]
        public ActionResult InsertItemdGridAjax(int OrderID)
        {
            //Omitted Code

            //Get List of Order Items
            List<OrderItem> list = ordersRepository.GetOrderItemsTK(OrderID));

            return View(new GridModel
            {
                Data = list,
                Total = list.Count
            });
        }
