Yep, the problem was with the JSON format I was sending from the controller. I am using a 3rd party web service (based on <a href="http://servicestack.net/" rel="nofollow">ServiceStack</a>). In the controller I was 'reading' the web response in a string (which was a JSON string), and pass it further. The problem was that the JSON string returned was between " ", and somehow the dataSource cannot handle it. So, my solution was based on your example above: I created a model, a collection and I returned the collection. Result: everything worked perfect. The JSON returned was no longer between " " and the dataSource object was initialized properly. Here is the code: ClientiController.cs <pre><code>public class ClientiController : Controller { public JsonResult Index() { StreamReader sr = null; string json = string.Empty; try { WebRequest request = WebRequest.Create("urlGoesHere"); using (WebResponse response = request.GetResponse()) { sr = new StreamReader(response.GetResponseStream(), true); json = sr.ReadToEnd(); } } catch { return Json("", JsonRequestBehavior.AllowGet); } JavaScriptSerializer serializer = new JavaScriptSerializer(); ClientiCollection collection = serializer.Deserialize<ClientiCollection>(json); return Json(collection, JsonRequestBehavior.AllowGet); } } </code></pre> Client.cs <pre><code>public class Client { public string ID { get; set; } public string RAGIONE_SOCIALE { get; set; } } </code></pre> ClientiCollection.cs <pre><code>public class ClientiCollection { public IEnumerable<Client> ClientiList { get; set; } } </code></pre> HTML <pre><code><input id="kendoCboClienti" /> <script type="text/javascript"> $(document).ready(function () { var clientiDataSource = new kendo.data.DataSource({ transport: { read: { url: "/Clienti/", dataType: "json" } }, schema: { data: "ClientiList" } }); $("#kendoCboClienti").kendoComboBox({ dataTextField: "RAGIONE_SOCIALE", dataValueField: "ID", dataSource: clientiDataSource, }); }); </script> </code></pre> However, I have ~8000 records to be displayed and the combobox it's a bit slow (~1.5 sec on opening). I'm not sure if I could somehow improve the response of it, without modifying the server in any way. P.S. Thanks a lot, Igorrious!

1. COYou are welcome! There a few things you can try, one is to take a look at this Telerik documentation: [Binding to Local or Remote Data](http://www.kendoui.com/documentation/ui-widgets/combobox/overview.aspx). There are ServerPaging and PageSize parameters on the datasource to explore. Your webservice is returning a list of clients. Perhaps adding an alphabet A B C D etc... filter prior to loading the combobox, would allow you to only bind a subset of the data to the combobox. If user selects letter 'A' then only show client's names starting with letter A in the combobox. Good luck!

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
