綁定模型到MVC Telerik網格拋出錯誤（ControllerContext空例外）

Question

在我看來，我有多個telerik MVC網格渲染。 但我只有一個問題。

模型如何與partialview綁定沒有區別。

這個例外給出了任何線索如何解決它。

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() 
) 

腳本：

function Record_onRowDataBound(e) { 
    var grid = $(this).data('tGrid'); 
}

那麼我已經修好了。
希望我的回答可能對您有類似問題的任何人有用。

解決方案：在示範

public class MyModel:Controller 
{ 
} 

避免繼承Controller類：控制器
