在我看来，我有多个telerik MVC网格渲染。 但我只有一个问题。
模型与部分视图的绑定方式没有区别。
此异常是否提供了解决方法的任何线索。

<小时/> 控制器：
[GridAction]
public ActionResult CopaySummaryLevel(int PBMID)
{
CopayModel cModel = new CopayModel();
List<CopayModel> _CopayModel = cModel.GetSummaryLevelCopay(PBMID);
return PartialView("_CopayGridSummaryLevel", new GridModel<CopayModel>
{
Data = _CopayModel
});
}
查看：
@model IEnumerable<HRORx.Models.BenefitsFormularyModel>
@using Telerik.Web.Mvc.UI
<h4>
Summary Level Copay</h4>
@(Html.Telerik().Grid<HRORx.Models.CopayModel>()
.Name("CopaySummaryLevel")
.Columns(columns =>
{
//columns.Bound(e => e.PharmacyType).Title("Pharmacy Type");
columns.Bound(e => e.OutOfPocketRangeStart);//.Title("OP Start");
//columns.Bound(e => e.OutOfPocketRangeEnd).Title("OP End");
//columns.Bound(e => e.FlatCopayAmount).Title("Flat Fee");
//columns.Bound(e => e.PercentCopayRate).Title("% Copay");
//columns.Bound(e => e.MinimumCopay).Title("Min. Copay");
columns.Bound(e => e.MaximumCopay);//.Title("Max. Copay");//.Format("{0:c}")
})
.ClientEvents(events => events.OnRowDataBound("Record_onRowDataBound"))
.ClientEvents(ev => ev.OnComplete("ShowOrHide"))
.DataBinding(dataBinding => dataBinding.Ajax().Select("CopaySummaryLevel", "BenefitsFormulary", new { PBMID = Model.FirstOrDefault().HealthPlanMappingID }))
.Pageable(paging => paging.PageSize(3))
.NoRecordsTemplate("No Summary Level Copy Information is available for this Medication.")
.Sortable()
)
脚本：
function Record_onRowDataBound(e) {
var grid = $(this).data('tGrid');
}
答案 0 :(得分：2)
嗯，我已经解决了这个问题 希望我的回答对任何有类似问题的人都有用。
避免将Controller类继承到Model
public class MyModel:Controller
{
}
