我正在尝试使用提供经销商列表的Web API,并尝试将其绑定到mvc中的DropdownList
。但是,我遇到了一个错误:
其他信息:DataBinding:'System.String'不包含名为'DealerName'的属性。
我正在使用的服务是返回经销商详细信息列表,我将在mvc中显示该网格,其中包含经销商名称和声明月<的两个下拉列表/ strong>用于搜索条件。所以,我创建了一个ViewModel来累积服务的结果,并使用两个addtional属性来在下拉列表中进行绑定。以下是代码:
Web服务结果 - 此类的IEnumerable列表:
public class DealerReportResponse
{
public string DealerCode { get; set; }
public string DealerName { get; set; }
public string StatementReceivedOnDate { get; set; }
public int StatementReceivedOnDay { get; set; }
public string StatementReceivedOnMonth { get; set; }
}
public class DealerReportViewModel
{
public List<string> DealerName { get; set; }
public List<string> DealerStatementMonth { get; set; }
public List<DealerReportResponse> DealerReportDetails { get; set; }
}
public ActionResult Index()
{
try
{
DealerReportViewModel model = new DealerReportViewModel();
var serviceHost = //url;
var service = new JsonServiceClient(serviceHost);
var response = service.Get<IEnumerable<DealerReportResponse>>(new DealerReportRequest());
if (response != null)
{
model.DealerName = response.Select(x => x.DealerName).Distinct().ToList();
model.DealerStatementMonth = response.Select(x => x.StatementReceivedOnMonth).Distinct().ToList();
model.DealerReportDetails = response.ToList();
return View("DealerReportGrid", model);
}
else
{
//do something
}
}
catch (Exception ex)
{
//catch exception
}
}
<!-- Search Box -->
@model DealerFinancials.UI.Models.DealerReport.DealerReportViewModel
<div id="searchBox">
@Html.DropDownListFor(m => m.DealerName,
new SelectList(Model.DealerName, "DealerName", "DealerName"),
"All Categories",
new { @class = "form-control", @placeholder = "Category" })
</div>
但是,我无法将DealerName列表绑定到下拉列表。我不确定错误。如果我错过了将我的模型传递给View的内容,请提供帮助。
答案 0 :(得分:1)
生成SelectList时出错:您需要从Model.DealerReportDetails
生成,而不是从Model.DealerName
生成。因此,而不是new SelectList(Model.DealerName, "DealerName", "DealerName")
使用
new SelectList(Model.DealerReportDetails , "DealerName", "DealerName")
@model DealerFinancials.UI.Models.DealerReport.DealerReportViewModel
<div id="searchBox">
@Html.DropDownListFor(m => m.DealerName,
new SelectList(Model.DealerReportDetails , "DealerName", "DealerName"),
"All Categories",
new { @class = "form-control", @placeholder = "Category" })
</div>
