【问题描述】:
有问题的网格是一个简单的位置列表,基于此集合:
public class Locations : BaseGrid
{
public string zipCode { get; set;}
public string city { get; set; }
public string state { get; set; }
public string timeZone { get; set;}
public IPagination<Location> LocationList { get; set; }
}
还有这个实体:
[DataContract] // DataContract/DataMember used for JsonSerializer
public class Location
{
public int ID { get; set; }
public string Address;
public string AlternateSupportingLocationNumber;
public string City;
public string CompanyName;
[DataMember]
public string CTU;
public string Description;
public double Distance;
[DataMember]
public string LocationNumber;
public string ManagerName;
public string PhoneNumber;
public string State;
public string SupportingLocationNumber;
public string TimeZone;
public string ZipCode;
public bool IsInPhysicalInventory;
public bool IsEslOwned;
}
控制器,如下所示:
public ActionResult NearestStoreCoverage( Locations locations )
{
if ( string.IsNullOrEmpty( locations.SortBy ) )
locations.SortBy = "Distance";
var list = _locationService.NearestStoreCoverage( locations, 50, ModelState );
locations.LocationList = list.AsPagination(locations.Page ?? 1, list.Count);
//go get locations that are close
return View( "Details/NearestStoreCoverage", locations );
}
获取视图的位置列表作为 Locations 模型的 LocationList 成员,并填充此控件:
<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<Locations>" %>
<%@ Import Namespace="Models.Common"%>
<div class="detailSection" style="width:98%">
<h1>Locations close to Zip Code -- <%=Model.zipCode %></h1>
<div>
<%= Html.Grid(Model.LocationList).Columns(column =>
{
column.For(x => x.LocationNumber)
.Named(Html.SortByLink("Location","LocationNumber"));
column.For(x => x.Distance.ToString("N2")).Named(
Html.SortByLink("Distance", "Distance"));
column.For(x => x.PhoneNumber.ToFormattedString()).
Named(Html.SortByLink("Phone Number",
"PhoneNumber"));
column.For(x => x.Address).Named(
Html.SortByLink("Address", "Address"));
column.For(x => x.City).Named(
Html.SortByLink("City", "City"));
column.For(x => x.State).Named(
Html.SortByLink("State", "State"));
column.For(x => x.ZipCode).Named(
Html.SortByLink("ZipCode", "ZIpCode"));
})
.Attributes(style => "width:100%")
.Attributes(id => "locationClosesttoZipGrid")
.Empty("There are no locations close to this zipcode") %>
<%= Html.Pager( Model.LocationList ).Link( page => Html.WritePageLink( page ) )%>
</div>
</div>
运行时,运行时错误是
System.ArgumentException was unhandled by user code
Message=The property Models.Common.Location.LocationNumber could not be found.
Source=System.Web.Mvc
InnerException:
(我删除了客户端的堆栈跟踪,反正很无聊)
但是,如果您调试并查看模型(这是来自 Html.Grid(Model.LocationList).Columns),您可以清楚地看到 LocationNumber 已填充:
A look at the Model in the debugger http://img839.imageshack.us/img839/6538/34gridresults.png
认为它不会变得陌生?如果我注释掉对 LocationNumber 的引用,调试器会允许距离和电话号码,然后在地址上再次失败(显然也存在)。
我已尝试重建,并已对所有相关符号进行 F12 操作,以确保它们到达我认为应该去的地方。
调试器不让我查看 x,这很糟糕。知道可能出了什么问题,或者至少如何开始查找?
