    <p><strong>Why don't you migrate your ASMX webservice to WCF?</strong></p> <p>The WCF API in .NET Framework 3.5 supports JSON web services natively.</p> <p>In addition Microsoft declared ASMX as "legacy technology", and suggests "Web services and XML Web service clients should now be created using Windows Communication Foundation (WCF)". (<a href="http://msdn.microsoft.com/en-us/library/bb552872.aspx" rel="nofollow noreferrer">Source</a>).</p> <p>You may want to check out these links to get started:</p> <ul> <li><a href="http://dotnetslackers.com/articles/ajax/json-enabledwcfservicesinaspnet35.aspx" rel="nofollow noreferrer">JSON-Enabled WCF Services in ASP.NET 3.5</a></li> <li><a href="http://dotnetninja.wordpress.com/2008/05/02/rest-service-with-wcf-and-json/" rel="nofollow noreferrer">REST Service with WCF and JSON</a></li> <li><a href="http://dotnetslackers.com/articles/ajax/json-enabledwcfservicesinaspnet35.aspx" rel="nofollow noreferrer">Creating a JSON Service with WebGet and WCF 3.5</a></li> <li><a href="http://www.asp.net/downloads/starter-kits/wcf-rest/" rel="nofollow noreferrer">Microsoft WCF REST Starter Kit</a></li> <li><a href="http://msdn.microsoft.com/en-us/library/bb332338.aspx" rel="nofollow noreferrer">Hosting and Consuming WCF Services</a></li> </ul> <p>In addition, you may also want to read through the following example which I "extracted" from a self-hosted WCF project of mine. Self-hosted WCF services do not require IIS, but can be served from any managed .NET application. This example is being hosted in a very simple <em>C# Console Application</em>:</p> <p><strong>IContract.cs</strong></p> <pre><code>using System; using System.Collections; using System.Collections.Generic; using System.Runtime.Serialization; using System.ServiceModel; using System.ServiceModel.Web; namespace MyFirstWCF { [ServiceContract] public interface IContract { [OperationContract] [WebGet(ResponseFormat = WebMessageFormat.Json, UriTemplate = "/CustomerName/{CustomerID}")] string GET_CustomerName(string CustomerID); } } </code></pre> <p><strong>Service.cs</strong></p> <pre><code>using System; using System.Collections.Generic; using System.Runtime.Serialization; using System.ServiceModel; using System.ServiceModel.Activation; using System.ServiceModel.Syndication; using System.ServiceModel.Web; namespace MyFirstWCF { [ServiceBehavior(InstanceContextMode = InstanceContextMode.Single, ConcurrencyMode = ConcurrencyMode.Multiple)] [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.NotAllowed)] public class Service : IContract { public string GET_CustomerName(string CustomerID) { return "Customer Name: " + CustomerID; } } } </code></pre> <p><strong>WCFHost.cs</strong> (Console Application)</p> <pre><code>using System; using System.Collections.Generic; using System.ServiceModel; using System.ServiceModel.Web; using System.ServiceModel.Description; using System.Threading; using System.Text; namespace MyFirstWCF { class Program { private static WebServiceHost M_HostWeb = null; static void Main(string[] args) { M_HostWeb = new WebServiceHost(typeof(MyFirstWCF.Service)); M_HostWeb.Open(); Console.WriteLine("HOST OPEN"); Console.ReadKey(); M_HostWeb.Close(); } } } </code></pre> <p><strong>app.config</strong></p> <pre><code>&lt;?xml version="1.0" encoding="utf-8" ?&gt; &lt;configuration&gt; &lt;system.serviceModel&gt; &lt;services&gt; &lt;service name="MyFirstWCF.Service"&gt; &lt;endpoint address="http://127.0.0.1:8000/api" binding="webHttpBinding" contract="MyFirstWCF.IContract" /&gt; &lt;/service&gt; &lt;/services&gt; &lt;/system.serviceModel&gt; &lt;/configuration&gt; </code></pre> <p>The above example is very basic. If you build a request with <a href="http://www.fiddler2.com/" rel="nofollow noreferrer">Fiddler</a> to <code>http://127.0.0.1:8000/api/CustomerName/1000</code> it will simply return <code>"Customer Name: 1000"</code>.</p> <p>Make sure to set the <code>content-type: application/json</code> in the request header. To return more complex data structures, you will have to use Data Contracts. These are constructed as follows:</p> <pre><code>[DataContract] public class POSITION { [DataMember] public int AssetID { get; set; } [DataMember] public decimal Latitude { get; set; } [DataMember] public decimal Longitude { get; set; } } </code></pre> <p>You need to add .NET References to <code>System.RuntimeSerialization</code>, <code>System.ServiceModel</code> and <code>System.ServiceModel.Web</code> for this example project to compile.</p>

    1. COHmmm. Seems something is FUBAR on my machine. I do not have an option to create an AJAX WFC Service. Is there something I should install on top of VS2008?

    2. COYou can just create a normal WCF service; you can decorate your interface with attributes to indicate that the ResponseFormat will be JSON.

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.
