Привязка модели к MVC Telerik Grid генерирует ошибку (исключение нулевого значения ControllerContext)

Question

На мой взгляд, у меня есть несколько Telerik MVC сетки рендеринга. Но у меня проблема только с одним.

нет никакой разницы в том, как Модель связана с частичным представлением.

Это исключение дает какую-либо подсказку, как это исправить.

            {
                CopayModel cModel = new CopayModel();

                    Data = _CopayModel
                });
            }

Посмотреть:

  @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()
)

Автор сценария:

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

Answer 1

Ну, я исправил это.
Надеюсь, мой ответ может быть полезен любому из вас с подобной проблемой.

решение:

Избегайте наследования класса Controller в модели

public class MyModel:Controller
{
}
