Aggregate error: Object doesn't support property or method [count]

[Szymon]

Here is my razor code:

Html.Kendo().Grid<KendoDemoMvc.Models.Issue>()

       .Name("Issues")

       .DataSource(ds => ds.Ajax().ServerOperation(false)

           .Read("Issues", "Home")

           .PageSize(5)

           .Aggregates(aggr =>

           {

               aggr.Add(o => o.Value).Count();

           })

       )

       .Columns(col =>

           {

 

               col.Bound(x => x.Id);

               col.Bound(x => x.Name);

               col.Bound(x => x.Value)

                  .ClientGroupHeaderTemplate("(Total: #=count#)")

           ;

           })

        .Groupable()

       .Selectable()

       .Pageable()

       .Render()

       ;

and controller action

public ActionResult Issues([DataSourceRequest]DataSourceRequest request)

{

    DataSourceResult result = GetIssues().ToDataSourceResult(request);

 

    return Json(result);

}

I try to group by column Name on UI, but it throws me runtime js error:  Object doesn't support property or method [count]
Please help...

Hello Szymon,

I'm afraid that I'm not sure what may caused the error you have described, judging from the provided details. Could you please provide a small run-able sample in which this behavior can be observed locally?
