How to create Generic Handlers Application in ASP.NET

HTTP Handlers were used in previous versions of visual studio such as 2002 and 2003.Because these versions did not provide any user-friendly methods for creating the Handlers.Generic Handlers is the easiest way to create a New HTTP Handler.Now we are using visual studio 2010,this makes easier to create the Handlers in application.Visual studio 2010 provided many user-friendly methods for creating the handlers.
There are some steps to create the Generic Handlers application which are given below:-
Step 1:- First open your visual studio-->File -->New -->Website-->Select ASP.NET Empty website-->open Solution Explore-->Add a New webform (home.aspx).

Step 2:-  open Solution Explorer --> Right click on Website-->Add New Item-->Select Generic Handler .ashx as shown below -->click Add Button.


Step 3:- Write the following codes in the Generic Handler.ashx page.

<%@ WebHandler Language="C#" Class="GenericHandler" %>
using System;
using System.Web;

public class GenericHandler : IHttpHandler {
    public void ProcessRequest (HttpContext context) {
    public void ManageForm(HttpContext context)
  if (context.Request.Params["NewFeature"] == null)
   context.Response.Write("<h2>Select your category value from dropdwon list</h2>");
            context.Response.Write("<select name='NewFeature'>");
   context.Response.Write("<option> SC </option>");
   context.Response.Write("<option> PD </option>");
            context.Response.Write("<option> OTHERS </option>");
   context.Response.Write("<input type=submit name='Submit' value='Submit'></input>");
  if (context.Request.Params["NewFeature"] != null)
  context.Response.Write("Hi, you are selected: ");
  context.Response.Write(" Catogery,change it if wrong</br>");            
    public bool IsReusable {
        get {
            return false;
