I have been using the proscribed method of populating a RadMenu via a web service.  It used to work correctly when we were using the 2007 Q3 version.  We recently upgraded to the 2009 Q3 version of the Telerik controls and now this functionality doesn't work.  It calls the web service, the web service runs successfully, but nothing is ever returned.  Neither of the client functions for post item populating fire.  Not sure what is going on.  Any help is greatly appreciated.  I've included the code below.

 [WebMethod(EnableSession = true)]
    public RadMenuItemData[] GetMenuColumns(RadMenuItemData item, object context)
    {
        SqlConnection sCon = new SqlConnection(ConfigurationManager.ConnectionStrings["Soleran"].ConnectionString);
        IDictionary<string, object> contextDictionary = (IDictionary<string, object>)context;
        List<RadMenuItemData> result = new List<RadMenuItemData>();
        
        SqlDataAdapter adap = new SqlDataAdapter(QueryParse(contextDictionary["query"].ToString()),sCon);
        DataTable dt = new DataTable();
        adap.Fill(dt);
        foreach(DataColumn dc in dt.Columns)
        {
            RadMenuItemData itemData = new RadMenuItemData();
            itemData.Text = dc.ColumnName.ToString();
            itemData.Value = dc.ColumnName.ToString() + '·' + dc.DataType.ToString() + '·' + dc.Ordinal.ToString();
            result.Add(itemData);
        }

        return result.ToArray();
    }

<telerik:RadContextMenu id="rcmSummary" runat="server" EnableAutoScroll="True" OnItemClick="AddSumClick" OnClientItemPopulationFailed="itemPopulatedFailed" OnClientItemPopulated="itemPopulated" OnClientItemPopulating="itemPopulating">
                                                            <WebServiceSettings Path="Summary.asmx" Method="GetMenuColumns" />
                                                            <LoadingStatusTemplate>
                                                                Loading...
                                                            </LoadingStatusTemplate>
                                                            <CollapseAnimation Duration="200" Type="OutQuint" />
                                                            <Items>
                                                                <telerik:RadMenuItem runat="server" Text="Available Columns" ExpandMode="WebService">
                                                                </telerik:RadMenuItem>
                                                            </Items>
                                                        </telerik:RadContextMenu>

Hi Anthony,

The code seems to be similar as in our online demo where everything is working normally.
I suggest that you send us a sample project in a new support ticket.
