    Basic MVC Plumbing

    We are wanting to use Ext.Net.MVC with version 2.0 but having some issues getting the MVC examples to work under 2.0.

    The example we are looking at is in Dashboard.aspx with the JsonResult coming from DataController.cs. The controller gets called but the Store does not populate the Panel. Possibly I am not wiring the Store up with the Json that is coming back if it is coming back at all.

    I would appreciate any input on the following code:

    Here is the Store:
                        <ext:Store ID="Store1" runat="server" AutoLoad="true">
                                <ext:AjaxProxy Url="/Data/GetHomeSchema/" AutoDataBind="true" Json="true" >
                                    <ActionMethods Read="POST" />
                                        <ext:JsonReader Root="data">
                                 <ext:Model ID="Model1"  runat="server" AutoDataBind="true" >
                                        <ext:ModelField Name="Title" />
                                        <ext:ModelField Name="Items" />

    Here is the Controller Code
    public JsonResult GetHomeSchema()
                XElement document = XElement.Load(Server.MapPath("~/resources/images/HomeSchema.xml"));
                var defaultIcon = document.Attribute("defaultIcon") != null ? document.Attribute("defaultIcon").Value : "";
                var query = from g in document.Elements("group")
                            select new
                                Title = g.Attribute("title") != null ? g.Attribute("title").Value : "",
                                Items = (from i in g.Elements("item")
                                         select new
                                             Title = i.Element("title") != null ? i.Element("title").Value : "",
                                             Icon = i.Element("item-icon") != null ? i.Element("item-icon").Value : defaultIcon,
                                             Accordion = i.Element("accordion-item") != null ? i.Element("accordion-item").Value : "",
                                             MenuItem = i.Element("menu-item") != null ? i.Element("menu-item").Value : ""
                return Json(query.ToArray(), JsonRequestBehavior.AllowGet);

    Why do you set Root="data"? Can you show response from the server (you can get it from Fiddler or Firebug) ?
    I guess the issue is related with mismatch of model (root and field names) and response

    Thank you Vladimir for your very quick response.

    I was setting Root=?data? to match the mvc examples that I saw but I am not sure exactly what I should set this to. Also, I have been playing around with Fire Bug and Fiddler checking to see if the data comes back to the page but I am not quite sure how to determine if it has come back but I will play around with this more.

    Basically I am just trying to get the Dashboard.aspx in the MVC examples to work under version 2.0 and maybe one data grid. If we have that I am certain we are going to go with Ext.Net; it?s such a great framework and the MVC is very compelling.

    Thank you for any additional input you have on the markup.

    Update: Its working.

    Well, I have got it partially working, there were some changes I made within the <Tpl runat="server"> tag. Ext.Net is cool stuff!

    Thank you again Vladimir.
