WebForms custom / dynamic routing

Question

I\'m using Phil Haack\'s URL routing for WebForms and I would like to define a route that\'s \"dynamic.\" Let\'s say I have this route:

\"{any}.aspx\" -- goes to -->

Answer 1

It's in VB but this is how I do it:

 Routes.Add("Root", New Route("{*URLRequest}", New myRootRouteHandler()))

This does the same as yours, it catches the entire request but it then passes it off to my own custom route handler class:

Imports System.Web.Routing
Imports System.Security
Imports System.Web.Compilation
Imports System.Web

Public Class myRootRouteHandler
  Implements IRouteHandler
  Implements IRequiresSessionState

  Private Path As String

  Public Function GetHttpHandler(ByVal requestContext As RequestContext) As IHttpHandler Implements IRouteHandler.GetHttpHandler
    Dim url As String = Web.HttpContext.Current.Request.ServerVariables("SERVER_NAME")
    Dim Key As String = requestContext.RouteData.Values("URLRequest")
    Dim myConfig As New LoadMyConfig(url)
    Dim aspxToLoad As String = myConfig.getPageVirtualPath(Key)
    Dim page As myCustom_Page_Base = TryCast(BuildManager.CreateInstanceFromVirtualPath(aspxToLoad, GetType(myCustom_Page_Base)), myCustom_Page_Base)

    page.RequestContext = requestContext
    page.strRequestContext = Key
    page.mySettings = myConfig

    Return page

End Function

In my example I have overloaded System.ui.page so that every aspx page in my project can inherit certain properties automatically like for example the mySettings object which contains my apps settings.. This is why I dim page as myCustom_Page_Base, you can load it as a standard page.

The important bit is: BuildManager.CreateInstanceFromVirtualPath method this will load whatever aspx file you point to it..

Hope this helps..
