I found on the forum that sometimes they can use asp.net routing locally, but if they use it on server, it doesnt work. So, today I will show you how to fix it.
How to Implement URL Routing
1) Create a web site using VS 2008 C#.
2) Right click the project and add reference to System.Web.Routing dll (make sure you have Asp.Net 3.5 Service Pack 1 installed in your machine)
3) Add the following lines to web.config file
 |

Web.config Configuration
The application resides in IIS 6.0 and IIS 7.0 you should add the UrlRoutingModule class to the httpModules
<httpModules>
< add name=”UrlRoutingModule” type=”System.Web.Routing.UrlRoutingModule,System.Web.Routing,Version=3.5.0.0,Culture=neutral,PublicKeyToken=31BF3856AD364E35″ />
</httpModules>
For IIS 7.0 only
<system.webServer>
<modules>
< remove name=”UrlRoutingModule” />
<add name=”UrlRoutingModule” type=”System.Web.Routing.UrlRoutingModule,System.Web.Routing,Version=3.5.0.0,Culture=neutral,PublicKeyToken=31BF3856AD364E35″ />
</modules>
<handlers>
< add name=”UrlRoutingHandler” preCondition=”integratedMode” verb=”*” path=”UrlRouting.axd” type=”System.Web.HttpForbiddenHandler, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a” />
</handlers>
</system.webServer>
Global.asax file Configuration
Add Import directive to Import System.Web.Routing name space
<%@ Import Namespace=”System.Web.Routing” %>
Register Routes in Application_Start method
void Application_Start(object sender, EventArgs e)
{
RegisterRoutes(RouteTable.Routes);
}
public static void RegisterRoutes(RouteCollection routes)
{
routes.Add(“MemberList”, new Route
(
“member/{name}”,
new MemberRouteHandler(“~/member/userlist.aspx”)
));
}
The first parameter member/{name} which denote the url structure, here the url which starts /member/{name} (ex : /member/deepu/) will point physically to the following path ~/member/userlist.aspx
The above RegisterRoutes method register a class called MemberRouteHandler.cs
using System.Web.Compilation;
using System.Web.UI;
using System.Web;
using System.Web.Routing;
public interface IRoutablePage
{
RequestContext RequestContext { set; }
}
public class MemberRouteHandler : IRouteHandler
{
public MemberRouteHandler(string virtualPath)
{
this.VirtualPath = virtualPath;
}
public string VirtualPath { get; private set; }
public IHttpHandler GetHttpHandler(RequestContext
requestContext)
{
var page = BuildManager.CreateInstanceFromVirtualPath
(VirtualPath, typeof(Page)) as IHttpHandler;
if (page != null)
{
var routablePage = page as IRoutablePage;
if (routablePage != null) routablePage.RequestContext = requestContext;
}
return page;
}
}
Now we can create the Aspx pages to test the Routing. We need to create two aspx files member listing file and detail file.
Create a folder called member in root of the site. (you can keep any name but make sure you have to change in global.asx file in Route constructor “member/{name}”)
Create a aspx page inside the member folder called default.aspx
This page will have a list of Members in Tabular format. I am going to use asp.net List view control to achieve this.
<form id=”form1″ runat=”server”>
<asp:ListView ID=”lvUserList” runat=”server”>
<LayoutTemplate>
< table width=”50%” style=”background-color: lightgrey;” cellpadding=”2″ cellspacing=”1″
border=”0″>
< tr style=”background-color: white”>
<td width=”100″ align=”center”>
Member ID
< /td>
< td align=”center”>
Name
< /td>
< td width=”75″ align=”center”>
Age
< /td>
< td width=”50″>
< /td>
< /tr>
< asp:PlaceHolder ID=”itemPlaceholder” runat=”server” />
< /table>
< /LayoutTemplate>
< ItemTemplate>
< tr style=”background-color: white”>
<td align=”center”>
<asp:Label ID=”lab” Text=’<%# DataBinder.Eval(Container.DataItem, “MemberID”)%>’
runat=”server” />
< /td>
< td>
< asp:Label ID=”Label1″ Text=’<%# DataBinder.Eval(Container.DataItem, “Name”)%>’ runat=”server” />
< /td>
< td align=”center”>
<asp:Label ID=”Label2″ Text=’<%# DataBinder.Eval(Container.DataItem, “Age”)%>’ runat=”server” />
< /td>
< td align=”center”>
<a href=”<%= ResolveUrl(“~/member/”)%><%# DataBinder.Eval(Container.DataItem, “Name”)%>”>
Detail</a>
< /td>
< /tr>
< /ItemTemplate>
< ItemSeparatorTemplate>
< br />
< /ItemSeparatorTemplate>
< /asp:ListView>
< /form>
Above markup will have a list of members and the hyper link column you can see the url structure which is defined in gloabal.asax file RouteMethod pattern.
<a href=”<%= ResolveUrl(“~/member/”)%><%# DataBinder.Eval(Container.DataItem, “Name”)%>”>
ResolveUrl(“~/member/”) = point to member folder from the root
<%# DataBinder.Eval(Container.DataItem, “Name”)%> = second parameter Member Name. [for ex: ResolveUrl("~/member/deepu") ]
Default.aspx.cs code behind
using System;
using System.Collections.Generic;
using System.Linq;
public partial class Memeber
{
public int MemberID { get; set; }
public string Name { get; set; }
public int Age { get; set; }
}
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
BindUsers();
}
}
void BindUsers()
{
var items = new List<Memeber>()
{
new Memeber {MemberID = 1,Name = “Arjun”, Age = 1},
new Memeber {MemberID = 2,Name = “Deepu”, Age = 29},
new Memeber {MemberID = 3,Name = “Rakesh”, Age = 31},
new Memeber {MemberID = 4,Name = “Abhilash”, Age = 21},
};
lvUserList.DataSource = items.ToList();
lvUserList.DataBind();
}
We have completed the listing page. The next page will be the detail page which will be rendering the member name from the URL routing.
userlist.aspx page Markup
<form id=”form1″ runat=”server”>
<div>
< asp:Label ID=”labMemberName” runat=”server” />
< /div>
< /form>
In the code behind file for the detail page you must implement IRoutablePage interface class.
Code behind :
public partial class user_userlist : System.Web.UI.Page, IRoutablePage
{
public System.Web.Routing.RequestContext requestContext;
#region IRoutablePage Members
public System.Web.Routing.RequestContext RequestContext
{
set { requestContext = value; }
}
#endregion
protected object RouteValue(string key)
{
if (requestContext != null && requestContext.RouteData != null)
{
return requestContext.RouteData.Values[key];
}
return null;
}
protected void Page_Load(object sender, EventArgs e)
{
object memberName = RouteValue(“name”);
if (memberName != null)
{
labMemberName.Text = memberName.ToString();
}
}
}
Note : If you are implementing url routing in GoDaddy server and you are using Session variables in the routing pages you should add Session module (manually)
<httpModules>
<add name=”Session” type=”System.Web.SessionState.SessionStateModule”/>
<add name=”UrlRoutingModule” type=”System.Web.Routing.UrlRoutingModule,System.Web.Routing,Version=3.5.0.0,Culture=neutral,PublicKeyToken=31BF3856AD364E35″ />
< /httpModules>
<system.webServer>
< modules>
<remove name=”Session” />
<add name=”Session” type=”System.Web.SessionState.SessionStateModule”/>
<remove name=”UrlRoutingModule” />
<add name=”UrlRoutingModule” type=”System.Web.Routing.UrlRoutingModule,System.Web.Routing,Version=3.5.0.0,Culture=neutral,PublicKeyToken=31BF3856AD364E35″ />
< /modules>
< handlers>
< add name=”UrlRoutingHandler” preCondition=”integratedMode” verb=”*” path=”UrlRouting.axd” type=”System.Web.HttpForbiddenHandler, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a” />
< /handlers>
< /system.webServer>
Note : Always use ResolveUrl for images OR css file or links to get the virtual path of the folder from the web site root in the routing pages.
for ex : [ ResolveUrl (“~/images/logo.jpg”) ]
Hope this help
