Telerik RadGrid在编辑模式下会导致值异常

我当然希望有人能在我还剩下一丝理智的时候帮助我：（

我有一个radgrid，通过LINQ查询进行数据绑定。它显示为它应该显示的，并且我添加了一个工作正常的详细信息按钮。但当我点击编辑按钮时，我会得到："JavaScript运行时错误：Sys.WebForms.PageRequestManagerServerErrorException：选择超出范围参数名称：value"

我仔细研究了我得到的价值观，我没有发现任何问题，无论是明显的还是其他的。我的网格如下（对不起，有点乱）：

我的代码指针，在与此有关的事件中是：

 private void LoadUnsoldVehicleGrid()
        {

            CAAData2DataContext db = new CAAData2DataContext();

            var ud = db.Updates
             .Where(c => c.Sold.Equals(false))
             .GroupBy(c => c.Vehicle)
            .Select(x => x.OrderByDescending(y => y.TimeStamp).First()).ToList();
            var unSoldVehicles = (from u in ud
                                  join v in db.Vehicles on
                                      u.Vehicle equals v.ID
                                  join c in db.Customers on
                                  v.Charity equals c.ID
                                  select new  
                                {
                                    status = u.Status,
                                    make = v.Make,
                                    model = v.Model,
                                    Year = v.Year,
                                    vin = v.VIN_,
                                    charity = c.Name,
                                    date = u.TimeStamp,
                                    id = u.Vehicle,
                                    salePrice = v.SalePrice,
                                    bid = v.MinimumBid,
                                    note=u.Note
                                }).OrderBy(z=>z.charity).ToList();
            RadGrid1.DataSource = unSoldVehicles;

        }

令人沮丧的是。。。这是有效的。我一定是无意中改变了什么，当我意识到这一切。。。ugh

如果有任何见解，我将不胜感激！
