Ever wondered, how the amazon rating system works with multiple items in the same page, here is a simple article to describe the basic bare bones needed to create an asynchronous rating module using ASP.NET , SQL Server and ..... AJAX
using System;
using System.Collections;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Web;
using System.Web.SessionState;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.HtmlControls;

namespace Rating
{
	/// <summary>
	/// Summary description for TestRating.
	/// </summary>
	public class TestRating : System.Web.UI.Page
	{
		protected System.Web.UI.WebControls.Label Label1;
	
		private void Page_Load(object sender, System.EventArgs e)
		{
			int NumViewed = 5;
			int RatedBy = 4;
			int Score = 20;
			// Put user code to initialize the page here
			Label1.Text = "<iframe src='Rate.aspx?Views=" + NumViewed + "&id=" + Convert.ToInt32(Request.QueryString["Qid"]) + "&itype=Q" + "&RatedBy=" + RatedBy + "&Score=" + Score + "' width='350' Height='28' frameborder='0' bgcolor='#F2EFE0'></iframe>";
		}

		#region Web Form Designer generated code
		override protected void OnInit(EventArgs e)
		{
			//
			// CODEGEN: This call is required by the ASP.NET Web Form Designer.
			//
			InitializeComponent();
			base.OnInit(e);
		}
		
		/// <summary>
		/// Required method for Designer support - do not modify
		/// the contents of this method with the code editor.
		/// </summary>
		private void InitializeComponent()
		{    
			this.Load += new System.EventHandler(this.Page_Load);

		}
		#endregion
	}
