No results in json from remote data source

[Michael Harry]

hi all, new to kendo, new to json. Can't seem to get any data into a kendo.data.DataSource. Am using the new 2012 q1 mobile release and ASP.NET MVC 3. Here's my code:

js:

    // create a template using the definition on the application page (the .cshtml file)
    var templateFundingSources = kendo.template($("#template-funding-sources").html());
 
    dataSource = new kendo.data.DataSource({
        transport: {
            read: {
                url: "/Home/GetCardFundings", // the remove service url
                dataType: "json", // JSONP (JSON with padding) is required for cross-domain AJAX
 
                data: {
                    //additional parameters sent to the remote service
                    _cardId: cardID
                }
            }
        },
 
 
        schema: {
            data: "cardFunding",
            model: {
                id: "CardID",
                fields: {
                    CardID: {
                        type: "number",
                        nullable: false
                    },
                    RemainingBalance: {
                        type: "number"
                    }
                }
            }
        },
 
 
        change: function () { // subscribe to the CHANGE event of the data source
            $("#listview-card-fundings").html(kendo.render(templateFundingSources, this.view()));
        }
    });
 
 
    dataSource.read();

    //test data source to see it's defined 
    dataSource.add({ cardID: 4, remainingBalance: 34 });

and MVC code:

public JsonResult GetCardFundings(int _cardId)
        {
            List<CardFunding> cfs = new List<CardFunding>();
 
            CardFunding cf = new CardFunding();
            cf.CardID = 1;
            cf.RemainingBalance = 3;
            cfs.Add(cf);
 
            CardFunding cf1 = new CardFunding();
            cf1.CardID = 1;
            cf1.RemainingBalance = 3;
            cfs.Add(cf);
            return Json(cfs, JsonRequestBehavior.AllowGet);
        }

The server-side code gets called and returned, and no execptions are tripped anywhere there or in the .js.
Any help greatly appreciated.

Kendo team: Awesome job on the project. Looking forward to mastering your framework.

Hello Michael,

I'm afraid that it is not clear what may be the caused for the behavior you have described. Therefore, could you please open a support ticket and provide a small runnable sample in which this issue can be observed locally. Meanwhile, you may take a look at this sample project which demonstrates DataSource populated through ASP.NET MVC action.
