Can you handle "it" for me?

Are you looking for a convenient way to return values (contents) from the server to the client and you don't want the overhead of a complete page?

Try HttpHandler.

public class Your_Handler : IHttpHandler
{
 private HttpContext _yourContext;

 public void ProcessRequest (HttpContext context)
 {
  _yourContext = context;
 _yourContext.Response.ContextType = "text/html";
 Your_Method();
 }

 public void Your_Method()
  {
   _yourContext.Response.Write("<p> VALUES </p>");
  }
}

To consume it, you can use AJAX like this:

$.ajax ({
 type: "GET",
 url: "Your_Handler.ashx",
 cache: false,
 success: function (html) {
  $(":#YourId").append(html);
  },
 error: function (html) {
  $("YourId").append("<p> Error on server. </p>");
  }
});
