Note:
means url looks like this if i press pravat sabat then
url would be like this http://localhost:1450/url_rout/User/hhhhh
means not showing pagename.
html code like this:-> take hello.aspx page and RegisterUser.aspx page and do the following code there
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="RegisterUser.aspx.cs" Inherits="RegisterUser" %>

.cs code-> i am using linq datasource for connectivity
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Data.Linq;
/// <summary>
/// Implements IDisplay interface which
/// </summary>
public partial class RegisterUser : System.Web.UI.Page, IDisplay
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void ButtonRegister_Click(object sender, EventArgs e)
{
string uniqueName = TextBoxUniqueName.Text.Trim();
DataClassesDataContext dc = new DataClassesDataContext();
//getting users using unique name given by user.
var users = from u in dc.Users
where u.UniqueName == uniqueName
select u;
if (users.Count<User>() == 0)
{
//Registering new user
User user = new User();
user.UniqueName = uniqueName;
user.Name = TextBoxFullName.Text;
user.Summary = TextBoxSummary.Text;
dc.Users.InsertOnSubmit(user);
dc.SubmitChanges();
LabelMessage.Text = "Congratulations! The Name '" + uniqueName + "' is registered successfully.";
TextBoxFullName.Text = "";
TextBoxUniqueName.Text = "";
TextBoxSummary.Text = "";
LinqDataSource1.DataBind();
GridViewUserList.DataBind();
}
else
{
//unique name not available
LabelMessage.Text = "Sorry! The Name '" + uniqueName + "' is not available.";
}
}
protected void LinkButton1_Click1(object sender, EventArgs e)
{
Response.Redirect("~/A");
}
}
now open asax file and do the code like this:
<%@ Application Language="C#" %>
<script runat="server">
void Application_Start(object sender, EventArgs e)
{
// Code that runs on application startup
RegisterRoutes();
}
private static void RegisterRoutes()
{
System.Web.Routing.RouteTable.Routes.Add(
"Add_New_User", new System.Web.Routing.Route("Add_New_User",
new RouteHandler("~/RegisterUser.aspx")));
System.Web.Routing.RouteTable.Routes.Add(
"user", new System.Web.Routing.Route("User/{name}",
new UserRouteHandler("~/DisplayUser.aspx")));
System.Web.Routing.RouteTable.Routes.Add(
"A", new System.Web.Routing.Route("A",
new RouteHandler("~/hello.aspx")));
}
void Application_End(object sender, EventArgs e)
{
// Code that runs on application shutdown
}
void Application_Error(object sender, EventArgs e)
{
// Code that runs when an unhandled error occurs
}
void Session_Start(object sender, EventArgs e)
{
// Code that runs when a new session is started
}
void Session_End(object sender, EventArgs e)
{
// Code that runs when a session ends.
// Note: The Session_End event is raised only when the sessionstate mode
// is set to InProc in the Web.config file. If session mode is set to StateServer
// or SQLServer, the event is not raised.
}
</script>
take ,DisplayUser.aspx
and html code like this:
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="DisplayUser.aspx.cs" Inherits="DisplayUser" %>

}
}
public string UniqueName { get; set; }
}
if i click link button on below link button then

using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
public partial class hello : System.Web.UI.Page,IDisplay// this is needed to display routing
{
protected void Page_Load(object sender, EventArgs e)
{
}
}
