ASP.NET WebService test form

Is it possible to configure default ASP.NET WebService test form to support JSON? I mean the test form that built in in .NET framework...

Currently I have a WebService that decorated with [ScriptService], but when I testing it using built in test form page, it returns XML...I assume, this happens because test page sends Content-Type XML by default.

Thanks

EDIT (Example):
I have class:

public class Person
{
  public string FirstName { get; set; }
  public string LastName { get; set; }
}

Now I have ASP.NET WebService: 

[ScriptService]
public class PersonService : WebService
{
  [WebMethod]
  public Person GetDave()
  {
    Person dave = new Person();

    dave.FirstName = "Dave";
    dave.LastName = "Test";

    return dave;
  }
}

When I call this WebService from web page using jQuery AJAX, I receive JSON Person object {"FirstName":"Dave","LastName":"Test"} (not string) in JavaScript, but when I invoking this WebService from ASP.NET WebService Test Form (When I right click on ASMX file and use "Preview In Browser"),

enter image description here

It returns:

<?xml version="1.0" encoding="utf-8" ?> 
<Person xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://tempuri.org/">
  <FirstName>Dave</FirstName> 
  <LastName>Test</LastName> 
</Person>

What want, is when I invoke the service from test page, to see the same output:

{"FirstName":"Dave","LastName":"Test"}

It looks like I found a solution...it still not complete solution, but this is the way to go :)

In [Drive]:\[WindowsDir]\Microsoft.NET\Framework\[Version]\CONFIG folder, exists the file named DefaultWsdlHelpGenerator.aspx. This file contains the whole code needed to automatically generate test page using WSDL. Now I can use this code to write my own test page and make requests using jQuery and not using HTML form...then I can put in config file and this should work.

<webServices>
      <wsdlHelpGenerator href="WSTestPage.aspx"/>
</webServices>

Maybe somewhere exists more simple/ready way to do it, but I still not found it...

You can use the code below 

[WebMethod(Description = "Some Description")]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
public string FunctionName()
{           
    // Return JSON data
    JavaScriptSerializer js = new JavaScriptSerializer();
    string retJSON = js.Serialize(Object);
    return retJSON;
}

And also you need to add the reference.

Update

Here is the link which will explain about extending an existing ASP.NET Web Service to support JSON

Hope that helps

Add following references first

using System.Web.Script.Services;
using System.Web.Script.Serialization;

use the below code in your method, for converting any data into JSON Data format in end

JavaScriptSerializer serializer = new JavaScriptSerializer();
return serializer.Serialize(dr);

dr is array of DataRows from DataTable.Hope this will help You.
