Remote Binding, What am I missing?

[Cynthia]

@(Html.Kendo().Grid<Zeus.Models.QuestionGroup>()
        .Name("grid")
        .Columns(columns =>
        {
            columns.Bound(p => p.Id);
            columns.Bound(p => p.Name);
        })
        .HtmlAttributes(new { style = "margin:10px;height:230px;" })
        .DataSource(dataSource => dataSource
            .Ajax()
            .PageSize(20)
            .Read(read => read.Action("Answers2", "Survey"))
        )
)

Above is some MVC code.  I've tested this code using local binding and it works, but when I call it remotely and bind it, it doesn't.  However, it does trace into the following function:

       public ActionResult Answers2()
        {
/* SNIP */

            Models.Survey survey = modelSurvey.GetFull();

/* SNIP */

            return Json(survey.QuestionGroups);
        }

And I see the trace using Fiddler,  and I can debug it, but when the Json object is returned, nothing shows up in the grid.  There is data there, and Im getting no javascript errors.  Any idea what I'm missing?

Hello,

The JSON you are returning is not in a format known to the grid. I recommend checking the ajax binding help topic which shows how to bind the Kendo UI to an action method.

Yes.  Adding:

            DataSourceResult result = survey.QuestionGroups.ToDataSourceResult(request);
            return Json(result);

To the code seems to work.  It would have been very helpful if in this example:
http://demos.telerik.com/kendo-ui/web/grid/remote-data.html

The Remote_DataController.cs file showed that this is required., however it maybe that it is implied.
