Define the Route in "Application_Start" of "Global.asax". Also include the namespace "System.Web.Routing".
<%@ Import Namespace="System.Web.Routing" %>
<%@ Application Language="C#" %>
<script runat="server">
void Application_Start(object sender, EventArgs e)
{
// Code that runs on application startup
RegisterRoutes(RouteTable.Routes);
}
public static void RegisterRoutes(RouteCollection routeCollection)
{
routeCollection.MapPageRoute("RouteForArticle", "Articles/{id}/{Title}", "~/DetailPage.aspx");
}
Now drag and drop a GridView control from the Toolbox on the URLRouting.aspx page.
