Attempting to create an infinite scroll app using jquery and asp.net

I am attempting to create an infinite scroll app using asp.net and jquery.  I would like it to be able to pull 10 records at a time.  I did in fact find a somewhat half done solution but it keeps repeating the same information from an xml source.  Does anybody have an idea on how I can do this as a commenting system similar to facebook?  This is the code that I found in the default.aspx.cs file.  How could I make it so that I am only pulling 10 records per postback?

     [WebMethod]
        public static string Foo()
        {
            StringBuilder getPostsText = new StringBuilder();
            using (DataSet ds = new DataSet())
            {
                ds.ReadXml(HttpContext.Current.Server.MapPath("App_Data/books.xml"));
                DataView dv = ds.Tables[0].DefaultView;

                foreach (DataRowView myDataRow in dv)
                {
                    getPostsText.AppendFormat("<p><b>author:</b> {0}</br>", myDataRow["author"]);
                    getPostsText.AppendFormat("genre: {0}</br>", myDataRow["genre"]);
                    getPostsText.AppendFormat("price: {0}</br>", myDataRow["price"]);
                    getPostsText.AppendFormat("publish date: {0}</br>", myDataRow["publish_date"]);
                    getPostsText.AppendFormat("description: {0}</br></p>", myDataRow["description"]);
                }
                getPostsText.AppendFormat("<div style='height:15px;'></div>");

            }
            return getPostsText.ToString();
        }

Why do I get the feeling that every time I look into a JQuery, JavaScript or similar framework for help, the creator of the JQuery or JavaScript framework is short on instructions and doesn't follow through with examples of pulling data from databases?  The site is short on instructions.  I feel like every time I look for an example of somebody pulling data from a database, they always talk about stagnant content or loop through a for or while loop.  This is extremely frustrating!
