I started to create a service to attempt to replicate the same functionality of Facebook posts and that is to have the newest comments on top.  My concern is that the newest posts to the page are being listed on the bottom.  How do I reverse that and add the newest posts to the top?  Thanks!

Here is what I have so far.  In the service page, here is what I have:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.Text;
using System.ServiceModel.Web;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Data;
using System.Data.Sql;
using System.Data.SqlClient;
using System.Configuration;
using System.Web.Services;

namespace NorthWindInfiniteScroll
{
    // NOTE: You can use the "Rename" command on the "Refactor" menu to change the class name "Test" in code, svc and config file together.
    // NOTE: In order to launch WCF Test Client for testing this service, please select Test.svc or Test.svc.cs at the Solution Explorer and start debugging.
    [ServiceContract]
    public class Test
    {
        [OperationContract]
        [WebInvoke(Method= "POST",
            BodyStyle=WebMessageBodyStyle.Wrapped,
            ResponseFormat= WebMessageFormat.Json)]
        public string MyFunction(string Count)
        {
            

            return "The Count you passed in is: " + Count.ToString() + " " + DateControl().ToString() +  Control();
        }

        public DateTime DateControl()
        {

            DateTime datetime;

            datetime = DateTime.Now;

            return datetime;
        }

        public string Control()
        {
            string hello;

            LiteralControl literalcontrol = new LiteralControl();

            ImageButton imagebutton = new ImageButton();

            literalcontrol.Text = "<div><h1><b>hello world</b></h1></div>" + "<img id='Image1' src='Images/loading.gif'/>";
            

            hello = literalcontrol.Text;

            return hello;
        }
    }
}

And in the web page calling the service page, this is what I have:

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="CallWCF.aspx.cs" Inherits="NorthWindInfiniteScroll.CallWCF" %>

<!DOCTYPE html>

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title>Call WCF</title>
    <script src="Scripts/jquery-1.8.2.js" type="text/javascript"></script>
    <script type="text/javascript">

        var counter = 0;
        function CallMyService() {

            counter++;

            $.ajax({
                type: "POST",
                url: "Test.svc/MyFunction",
                data: '{"Count": "' + counter + '"}',
                contentType: "application/json",
                success: ServiceSucceeded,
                error: ServiceFailed
            });
        }

        function ServiceFailed(result) {

            Log('Service call failed: ' + result.status + ' ' + result.statusText);
        }

        function ServiceSucceeded(result)
        {
            resultObject = result.MyFunctionResult;
            Log("Success: " + resultObject);
        }

        function Log(msg) {
            $("#logdiv").append(msg + "<br />");
        }
    </script>
</head>
<body>
    <input id="Button1" type="button" value="Execute" onclick="CallMyService();" />
    <div id="logdiv">
    
    </div>    
</body>
</html>

Instead of:
$("#logdiv").append(msg + "<br />");

Open in new window

Try:
$("#logdiv").prepend(msg + "<br />");
