Demo WebService isn't responding - Newbie Question

[KI performance]

Hello everbody,

i am unable to configure my WCF WebService and RadTreeView Control to work together 'On Demand', and because i am absolutly new with WebServices, i have no clue what is the problem. Anybody can give me a hint? By the way, i strongly use the following Demo of Telerik: http://www.telerik.com/help/aspnet-ajax/treeview-load-on-demand-wcf.html and http://demos.telerik.com/aspnet-ajax/treeview/examples/programming/performance/defaultcs.aspx

myTopBarNavigation.svc

<%@ ServiceHost Language="C#" Debug="true"

myTopBarNavigation.svc.cs

namespace kibp.nordlb.layout.ISAPI.kibp.nordlb.layout
{
    class NodeData
    {
        private string text;
        {
            get { return text; }
            set { text = value; }
        }
    }

    //[BasicHttpBindingServiceMetadataExchangeEndpoint]
    [ServiceContract]
    [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
    class kibpTopBarNavigation
    {
        [OperationContract]
        public IEnumerable GetNodes(RadTreeNodeData node, IDictionary context)
        {
            int numberOfNodes = 100;
            List<NodeData> nodes = new List<NodeData>();
            for (int i = 0; i < numberOfNodes; i++)
            {
                NodeData nodeData = new NodeData();
                nodeData.Text = "Node " + i;
                nodes.Add(nodeData);
            }
            return nodes;
        }
    }
}

Error Message @Fiddler:

HTTP/1.1 500 System.ServiceModel.ServiceActivationException

P.s.: The Request looks like this:

http://localhost/_vti_bin/xxxx/myTopBarNavigation.svc/GetNodes

and tries to send the following Data:

{"node":{"Text":"Root Node","Value":null,"Key":null,"ExpandMode":3,"NavigateUrl":null,"PostBack":true,"DisabledCssClass":null,"SelectedCssClass":null,"HoveredCssClass":null,"ImageUrl":null,"HoveredImageUrl":null,"DisabledImageUrl":null,"ExpandedImageUrl":null,"ContextMenuID":"","Checked":false},"context":[]}

I've build a Interface with following Content:

myTopBarNavigationInterface.cs

namespace xxxx.xxxx.xxxx.ISAPI.xxxx.xxxx.xxxx
{
    [ServiceContract]
    interface myTopBarNavigationInterface
    {

        [OperationContract]
        [WebInvoke(Method = "POST", BodyStyle = WebMessageBodyStyle.WrappedRequest, RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json)]
        IEnumerable GetNodes(RadTreeNodeData node, IDictionary context);
    }
}

modified: myTopBarNavigation.svc.cs

namespace xxxx.xxxx.xxxx.ISAPI.xxxx.xxxx.xxxx
{

    class NodeData
    {
        private string text;

        public string Text
        {
            get { return text; }
            set { text = value; }
        }
    }

    [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
    class myTopBarNavigation : myTopBarNavigationInterface
    {
        public IEnumerable GetNodes(RadTreeNodeData node, IDictionary context)
        {
            int numberOfNodes = 100;
            List<NodeData> nodes = new List<NodeData>();
            for (int i = 0; i < numberOfNodes; i++)
            {
                NodeData nodeData = new NodeData();
                nodeData.Text = "Node " + i;
                nodes.Add(nodeData);
            }

            return nodes;
        }
    }
}

With this modified edition, i see that the WebService is called and it jumpes into the correct function. Btw. i dont know why but the webservice is called three times and the page returns 401 as error, but this is another story :)

Hi Sascha,

Does this mean that the problem is solved?
