asp.net web form Custom Router Handler - c#

I am using a custom route handler for a webforms application. I am using routes to determine localization. ie:
if the url has es or fr in the route it will load either spanish or french resources.
for example:
www.someroute/es/checkstuff/checkstuff.aspx
will load:
www.someroute/checkstuff/checkstuff.aspx with the spanish resources.
I am configuring the custom routes in global.asax via:
protected void Application_Start(object sender, EventArgs e)
{
RegisterRoutes(RouteTable.Routes);
}
public static void RegisterRoutes(RouteCollection routes)
{
foreach (var value in _customRoutes)
{
routes.Add(value.RouteName, new Route(value.Route, new CustomRouteHandler(value.ResolvedRoute)));
}
}
where _customroutes is a list of routes.
Is there a way to do this with some kind of pattern matching so I can avoid adding a specific route for each page in the application. While I know I could use a t4 template to generate the routes, I guess I am looking for a dynamic way to create the list

I discovered that it was simpler to use MapPageroute than route.Add. With MapPageRoute I was able to use wildcards and with two entries:
routes.MapPageRoute("Spanish", "es/{*page}", "~/{page}");
routes.MapPageRoute("Kreyol", "fr/{*page}", "~/{page}");
I was able to provide the required routing for Spanish and Kreole pages.
Thanks to all for your help.

I would handle the language-part through some plain old Rewrite with an HttpModule in the BeginReguest handler and let the Routing engine take care of the rest.
Remember that the Routing mechanism takes place far later than BeginRequest so you can safely determine the language, set the CultureInfo on your thread and rewrite the request url to no contain the language-part, and your Routing would never know about it.

URL Routing .Net 4.5 Webforms

I have a webforms app that I would like to add some routing in so when a user types in www.mySite.com/Brd it will take them to a specific page. I can get this to work if I put an argument in, however I don't want any. Here is what I have in my application start method
protected void Application_Start(object sender, EventArgs e)
{
RegisterRoute(System.Web.Routing.RouteTable.Routes);
}
void RegisterRoute(System.Web.Routing.RouteCollection routes)
{
routes.MapPageRoute("Route1", "Rep", "~/SalesRep/SalesRepHome.aspx");
routes.MapPageRoute("Route2", "Brd", "~/Board/BrdLogin.aspx");
}
The route for the Brd takes me to www.mysite.com/BrdLogin.aspx without the subdirectory and the Rep route does nothing. Could someone point me in the right direction?
Try adding this line to your RegisterRoutes method...
routes.EnableFriendlyUrls();
Make sure you're also referencing the Microsoft.AspNet.FriendlyUrls assembly
Also, try putting a forward slash after Rep and Brd e.g.
routes.MapPageRoute("Route1", "Rep/", "~/SalesRep/SalesRepHome.aspx");
routes.MapPageRoute("Route2", "Brd/", "~/Board/BrdLogin.aspx");

404 error with MapPageRoute() routing a aspx page within a folder

Trying to route in webforms, getting a 404.
I have set up my global.asax.cs file as follows using System.Web.Routing;
protected void Application_Start(object sender, EventArgs e)
{
RegisterRoutes(RouteTable.Routes);
}
private void RegisterRoutes(RouteCollection routes)
{
routes.MapPageRoute("ProfilePage",
"Profile",
"~/Manager/Profile.aspx");
}
profile.aspx is located within the manager folder. No idea why it's not working. Would be grateful if someone could make some suggestions I am fairly new to asp.net.
I am expecting the url localhost:60008/Manager/Profile/ to load the Profile.aspx page.
The second parameter specifies the URL. Try:
routes.MapPageRoute("ProfilePage",
"Manager/Profile",
"~/Manager/Profile.aspx");
You have it right the first time. Here a valid routing
routes.MapPageRoute("", "YourPage", "~/Your/full/url.aspx", true);
The first para can be let empty, the second is the one you are going to use, the third is the url of your page, the last [optional] is to check if the file exist physically or not.
I believe where the error comes is how you use it, for a hyperlink you would say
NavigateUrl="~/YourPage"
In a html anchor
href="~/YourPage" runat="server"
In the browser address bar it will show like this http://YourDomain.com/YourPage/
That's the way it works for me. Personally having to put the folders in there defeat the purpose of using routing no?

How to change content based on the page name instead of querystring in asp.net

I've a site, we are using ASP.NET 4.0, and right now our products content is managed like this
www.franko1.com/products.aspx?serie=2000
where the querystring serie is the product ID, so its value is taken and then the contents is extracted from the database.
Now for SEO reasons, we've been asked to change the urls, so now they have to look like this:
What the boss want | Current Urls
--------------------------------------------------------------------------------
www.franko1.com/Relief_Valves | www.franko1.com/products.aspx?serie=2000
www.franko1.com/Inline_Flame_Arrester | www.franko1.com/products.aspx?serie=1000
www.franko1.com/Vent_Hatch | www.franko1.com/products.aspx?serie=3000
and so on ...
Right now, we are using a masterpage and the products.aspx and as I said, we take the querystring serie and we show the content based on its value, I have no idea how to do this using asp.net, I have read about ISAPI_Rewrite but I was wondering if there is a technique to approach this without dealing with the IIS server....
Well I don't know if I was clear, It is hard to explain,
No need for that. You can achieve this via routing (It's not just for MVC).
Routing has been available as a stand alone module for a while now, but with ASP.Net 4.0 you can now use routing for WebForms just as easily as you can with MVC.
You will need to add some routing to your Global.asax
public class Global : System.Web.HttpApplication
{
protected void Application_Start(object sender, EventArgs e)
{
RegisterRoutes(RouteTable.Routes);
}
public static void RegisterRoutes(RouteCollection routeCollection)
{
routeCollection.MapPageRoute("Products", "Products/{Name}", "~/Products.aspx");
}
}
And with that you can now reference the route values in your page like so:
protected void Page_Load(object sender, EventArgs e)
{
string prodName = Page.RouteData.Values["Name"].ToString();
//Do lookup, etc...
}
Your URLs will end up looking like this:
www.domain.com/products/Relief_Valves
www.domain.com/products/Widgets
www.domain.com/products/TrashCans
etc..
Nice and easy... and clean!
URL rewriting was made just for exactly this purpose. The problem is that it really doesn't work with variable content directly appended to the root URL. There really isn't enough information for URL routing to separate such URLs from the rest of your URLs.
Would your boss accept www.franko1.com/p/Relief_Valves ?

ASP.NET 4.0 Routing and Default.aspx (How write A Handler? Is It Necessary Or Not)

i want to route Default.aspx to another URL when page starts.
my global.asax is like this :
protected void Application_Start(object sender, EventArgs e)
{
RegisterRoutes(RouteTable.Routes);
}
public static void RegisterRoutes(RouteCollection routes)
{
routes.MapPageRoute(
"Default", // Route name
"My Site", // URL with parameters
"~/Default.aspx" // Parameter defaults
);
}
should i write a handler for my purpose?
(i found some samples for .net 3.5 and MVC but what about .net 4 web forms)
if yes how can i write it?
EDIT:
what this line exactly do?
routes.Add("Default", new Route(string.Empty, new RouteHandler("~/Default.aspx")));
i am using web forms -> Not MVC
thanks in advace
Here's a specific example of how to deal with routing on asp.net 4.0 web forms (it's just under the mvc part).
http://weblogs.asp.net/scottgu/archive/2009/10/13/url-routing-with-asp-net-4-web-forms-vs-2010-and-net-4-0-series.aspx
The way you are approaching it is fine. You do have an error in the second parameter of your route. Well perhaps not an error, I dislike spaces in urls as they are actually the encoded spaces. Check out the guide.
Just noticed your edit.
Adding the route essentially creates a mapping between a url or url pattern (which you have as string.Empty which is a problem) and a handler which serves the request(You specify RouteHandler which I don't believe actually exists?). .net Provides a PageRouteHandler which allows you to specify which page responds to your request and deal with a couple other details like security defined on the physical structure of your site. Internally, MapPageRoute is simply calling routes.Add but using the PageRouteHandler.

Msdn style address URL localization possible implementation

I am trying to come up with idea how to implement msdn like localization based on address string
http://msdn.microsoft.com/en-us/library/system.string.aspx
http://msdn.microsoft.com/ru-ru/library/system.string.aspx
I tried to find various information about ASP.NET localization, but failed to find a description of strategy that can be used to get above result.
I am not very experienced with ASP.NET and would like to get some advice on how to implement something that will result in similar paths on my website(using best possible way with least code duplication for example).
I understand that I could duplicate both files in 2 folders. or 10 files in 10 folders if i got 10 cultures. But that sounds like not the best strategy. Is there some rewrite & parameter pass going on behind or ?
Update: I ended up implementing it the following way:
for my localizable pages I register routes to all current cultures ( in a generic method),
for example for help.aspx I register ru-ru/help/ and en-us/help/ routes, inside help.aspx (and other localizable pages, oop way) I analyze address string and retrieve desired language. After that I setup html contents matching the related culture provided in url.
Microsoft appear to be either rewriting the URLs, or taking advantage of custom routing in ASP.NET. They are using using the URL to determine which culture to select. They could have used a query string but the URLs would not look as good.
I'd suggest that you start by looking into ASP.NET MVC as it uses routing out of the box. Then modify the routes to match those used by MS above, before using them to apply a culture.
Where you will be hosting your application could have an impact on whether you can do similar things. If you are managing the whole server and not using shared hosting it will be easier to implement these things, especially URL rewriting. If you have to use ASP.NET 2.0 because you are in some aging corporate environment you will probably have an even more difficult time.
Valentin, try to use url routing:
1 - Add routing info to global.asax
void Application_Start(object sender, EventArgs e)
{
RouteTable.Routes.MapPageRoute("cultureCrossroad", "{culture}/Library/{article}", "~/library/ArticleHost.aspx");
}
2 - Create host page at ~/Library/ArticleHost.aspx
public partial class ArticleHost : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
// ! Here we have access to url's parts and can redirect user for desired page via Server.Transfer method.
var response = string.Format("culture: {0}<br/> article: {1}", Page.RouteData.Values["culture"], Page.RouteData.Values["article"]);
Response.Write(response);
}
}
