I there a simple way when using ASP.NET 4.0 routing with Web Forms to produce a route that will act as some kind of wildcard?
It seems to me that within WebForms, you have to specify a route for every page - I am looking for some kind of generic route that can be used where nothing specific is required, perhaps mapping directly from path to path so...
http://somedomain.com/folder1/folder2/page would possibly map to folder1/folder2/page.aspx
Any suggestions?
Thanks
You can match all remaining routes like this:
routes.MapPageRoute("defaultRoute", "{*value}", "~/Missing.aspx");
In this case, we know all routes, and want to send anything else to a "missing"/404 page. Just be sure to put this as the last route, since it is a wildcard and will catch everything.
Alternatively you could register a route the same way, but internally does mapping to a page, like this:
routes.Add(new Route("{*value}", new DefaultRouteHandler()));
That handler class would do your wildcard mapping, something like this:
public class DefaultRouteHandler : IRouteHandler
{
public IHttpHandler GetHttpHandler(RequestContext requestContext)
{
//Url mapping however you want here:
var pageUrl = requestContext.RouteData.Route.Url + ".aspx";
var page = BuildManager.CreateInstanceFromVirtualPath(pageUrl, typeof(Page))
as IHttpHandler;
if (page != null)
{
//Set the <form>'s postback url to the route
var webForm = page as Page;
if (webForm != null)
webForm.Load += delegate { webForm.Form.Action =
requestContext.HttpContext.Request.RawUrl; };
}
return page;
}
}
This is broken a bit in odd places to prevent horizontal scrolling, but you get the overall point. Again, make sure this is the last route, otherwise it'll handle all your routes.
