[Solved] Grid stopped working, and I didn't do anything

[Mike]

It worked yesterday, but not today. I didn't make any changes. Now it always displays "No items to display". I'm getting towards the end of my trial period (got a message when I loaded Visual Studio). Could that have something to do with it?

Here's the grid definition in the view:

@(Html.Kendo().Grid<CapEdit2.Models.Report>()
    .Name("SearchResultsGrid")
    .DataSource(ds => ds
        .Ajax()
        .Read(read => read
            .Action("GetSearchResults", "Report").Data("reportsReadData")
        )
        .PageSize(10)
    )
    .Columns(columns => 
    {
        columns.Bound(r => r.Id);
        columns.Bound(r => r.TransDate).Title("Trans Date").Format("{0:MM-dd-yyyy}"); 
        columns.Bound(r => r.Corporation.Name).Title("Corporation"); 
        columns.Bound(r => r.Headline); 
    })
    .Pageable()
    .Sortable()
)


Here's the server-side code that gets the data for the grid (I can see that it's working fine):

        public ActionResult GetSearchResults([DataSourceRequest]DataSourceRequest request, string company, DateTime startDate, DateTime endDate)
        {

            var context = new CapInternalContext();

            var query = (IQueryable<Report>)context.Reports
                    .Include("Corporation")
                    .Include("Stages");  

            var result = this.Json(query.ToDataSourceResult(request));
            return result; // I put a break point here, and always see results
        }

Thanks for your help!

Hi Mike,

this does not seem like a known issue. The trial part should not have any effect on it, tough.

That's good to know. What is the solution?

Hello,

Like I said, this does not seem like a known issue. At this point, the information you provided is not enough for us to determine what goes on. Given that your source code hasn't changed, the problem is most likely somewhere else - maybe in the data passed to it.

I've resolved the issue. Root cause was that the JSON data had circular references.
