Asp.net mvc 3 使用Teleriks网格进行自定义数据绑定

我有一个MVC3 Telerik应用程序。这是我的控制器：

    [GridAction]
    public ActionResult Index(GridCommand command)
    {
        IEnumerable<Order> data = GetData(command);
        var dataContext = new NorthwindDataContext();

        //Required for pager configuration
        ViewData["total"] = dataContext.Orders.Count();

        return View(data);
    }

    [GridAction(EnableCustomBinding = true)]
    public ActionResult _CustomBinding(GridCommand command)
  {
IEnumerable<Order> data = GetData(command);

var dataContext = new NorthwindDataContext();
return View(new GridModel 
{ 
    Data = data, 
    Total = dataContext.Orders.Count() 
});
}

    //Utility method which does custom paging and sorting using Linq
    private static IEnumerable<Order> GetData(GridCommand command)
    {
        var dataContext = new NorthwindDataContext();
        IQueryable<Order> data = dataContext.Orders;


        if (command.PageSize > 0)
        {
            data = data.Skip((command.Page - 1) * command.PageSize);
        }

        data = data.Take(5);
        return data;
    }

它调用我的函数\u CustomBinding，当我单步执行时不会抛出错误。导致此错误的原因是什么？

这意味着\u CustomBinding方法中发生了服务器端异常。您可以检查实际的服务器响应是什么-它将包含stacktrace。使用Fiddler或浏览器的开发工具检查服务器响应是什么

    @model IEnumerable<Telerik.Order>

     @(Html.Telerik().Grid(Model)
    .Name("Grid")
    .Columns(columns =>
    {
        columns.Bound(o => o.OrderID).Width(100);
        columns.Bound(o => o.Customer.ContactName).Width(200);
        columns.Bound(o => o.ShipAddress);
        columns.Bound(o => o.OrderDate).Format("{0:MM/dd/yyyy}").Width(100);
    })
                .DataBinding(dataBinding =>
                {
                    dataBinding.Ajax().Select("_CustomBinding", "Home").Enabled(true);
            })
        .Pageable(pager => pager.Total((int)ViewData["total"]))
        .EnableCustomBinding(true)
        .Sortable()
