    So I've got a grid that I believe is all set up correctly. I've confirmed that the data is coming through, and I've even checked that the AJAX call returns a success with the "ToDataSourceResult" JSON data.


    Unfortunately, the only problem is that the data doesn't display. This seems to only be an issue on read, as update, create and delete all work. Just can't retrieve the list of all items afterwards.


    My controller action looks like this: 

    public IActionResult Blog_Read([DataSourceRequest] DataSourceRequest request)
                var blogs = _blogService.GetPosts().Select(post => new BlogPostModel
                    Id = post.Id,
                    Title = post.Title,
                    Author = post.Author,
                    ShortDescription = post.ShortDescription,
                    Contents = post.Contents,
                    LastSaved = post.LastSaved,
                    Published = post.Published,
                    PublishedOn = post.PublishedOn
                var result = blogs.ToDataSourceResult(request);
                return Json(result);


    And my Grid View looks like this:

                .Columns(columns =>
                    columns.Bound(p => p.Title);
                    columns.Bound(p => p.Author).Width(120);
                    columns.Bound(p => p.LastSaved).Width(120);
                    columns.Bound(p => p.Published).Width(120);
                    columns.Command(command => { command.Edit(); command.Destroy(); }).Width(250);
                .ToolBar(toolbar => toolbar.Create())
                .Editable(editable => editable.Mode(GridEditMode.PopUp))
                .HtmlAttributes(new { style= "height:600px;"})
                .DataSource(dataSource => dataSource
                    .Events(events => events.Error("error_handler"))
                    .Model(model => model.Id(p => p.Id))
                    .Create(update => update.Action("Blog_Create", "BlogAdmin"))
                    .Read(read => read.Action("Blog_Read", "BlogAdmin"))
                    .Update(update => update.Action("Blog_Update", "BlogAdmin"))
                    .Destroy(update => update.Action("Blog_Delete", "BlogAdmin"))


    The correct JSON is returned, no javascript errors in the console, so I'm a little confused as to what this could be. Any help would be greatly appreciated.

    I solved this by adding 


    services.AddMvc().AddJsonOptions(options => options.SerializerSettings.ContractResolver = new DefaultContractResolver());


    to my Startup.cs ConfigureServices method.
