How do I handle url like this:
{subdomain}.{domainname}/{areas}/{controller}/{action}
For example: user1.contoso.com/Manage/User/View
I want it to be route:
{area} = Manage
{controller} = User
{action} = View
{username} = user1 // View action parameter
Any help would be greatly appreciated :-)
Generally routes are defined in the file Global.asax in the method RegisterRoutes
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
"Export", // Route name
"Export/{action}/{table}", // URL with parameters
new { controller = "Export", action = "AsExcel", table = "" } // Parameter defaults
);
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = "" } // Parameter defaults
);
}
With a definition like above you can use a separate route for ExportController such that the default action is AsExcel
in the case of route as the one you have described, I am not sure if Areas is part of the MVC pattern.
Still for what it is worth, you may have some benefit from this thread

I'm working with ASP.NET MVC3, I created my routes and compose my urls but I have something weird in my url after navigated in browser.
Url actually rendered: /controller/action/page.html
Url navigated: /controller/action/page.html#.V7cdQJh97cw
I think that maybe is SessionID but I can't know how to remove it.
Appreciate any helps!
Go to the RegisterRoute method of RouteConfig.cs file in the App_Start folder of your project where Default Routing rule is written there.
Route Rule:- ControllerName/ActionName/id
where id is optional. So you want to remove Id parameter ,then make Id=" ".
for example:-
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = "" } // Parameter defaults
);
}
I've created a system in MVC using the NerdDinner tutorial as a base to work off.
Everything was working fine until I used single action methods such as
Here is the global.asax.cs
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "mysample", id=UrlParameter.Optional }
);
which routes to
http:localhost/Home/mysample
i just want to create routes which has more than one action in the sense
http:localhost/<controller>/<action>/<params>
ex: localhost/mycontroller/myaction/details/myname
Any help much appreciated.
Thanks.
update 1:
i have writen router like this as
routes.MapRoute(
"myname", // Route name
"{controller}/{action}/{details}/{myname}", // URL with parameters
new { controller = "mycontroller", action = "myaction", details= "details", myname= "" } // Parameter defaults
);
and retried the value with following syntax as
String name=RouteData.Values["myname"].ToString();
it works fine .
but even though the url called as
localhost/mycontroller/myaction/details
its being routed to that controller and error is being thrown as null reference...
how to avoid it?
You can't define multiple actions in one MVC route.
In MVC routing configuration is used for mapping your Controlers and Actions to user friendly routes and:
Keep URLs clean
Keep URLs discoverable by end-users
Avoid Database IDs in URL
Understanding default route config:
routes.MapRoute(
name: "Default", // Route name
routeTemplate: "{controller}/{action}/{id}", // URL with parameters
defaults: new { controller = "Home", action = "mysample", id=UrlParameter.Optional }
);
The "routeTemplate" property on the Route class defines the Url
matching rule that should be used to evaluate if a route rule applies
to a particular incoming request.
The "defaults" property on the Route class defines a dictionary of
default values to use in the event that the incoming URL doesn't
include one of the parameter values specified.
Default route will map all requests, because it has defined default values for every property in routeTemplate, {} means that property is variable, if you not provide value for that param in URL, it will try to take default value if you provide it. In default route it has defined defaults for controller, action and id param is optional. That means if you have route like this:
.../Account/Login
It will take you to Account controller, Login action and because you didn't specified prop and it is defined as optional it will work.
.../Home
This will also work, and it will take you to Home contoller and mysample action
When you define custom route, like you did:
routes.MapRoute(
"myname", // Route name
"{controller}/{action}/{details}/{myname}", // URL with parameters
new { controller = "mycontroller", action = "myaction", details= "details", myname= "" } // Parameter defaults
);
You didn't specified myname as optional and you didn't specified it your route, that means that your URL: localhost/mycontroller/myaction/details wan't be handled by your custom route myname. It will be handled by default route. And when you try to access your myname param in controller it wan't be there and you will get null reference error. If you want to specifie default value of your parameter if not present in url you need to do that in your controller. For example:
public class MyController : Controller
{
public ActionResult MyAction(string details = "details", string myname = "")
{
...
and change your custom route to:
routes.MapRoute(
"myname", // Route name
"{controller}/{action}/{details}/{myname}", // URL with parameters
new { controller = "mycontroller", action = "myaction", details= UrlParameter.Optional, myname= UrlParameter.Optional } // Parameter defaults
);
But you can define only one controller and only one action, rest of the routeTemplate are parameters.
You can't define two action in one route. It make no sense.
I have a web site with something like this:
http://website/Controller/Action/Id
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Controller", action = "Action", id = UrlParameter.Optional } // Parameter defaults
);
Is there any way to route to the same action if the url changes to be
http://website/Action/Id
I was trying to change global.asax but nothing is working.
Based on how I'm reading your question, you're saying that you may only ever have one controller and want to be able to route all actions to that single controller?
If I'm reading it correctly, you should be able to do something similar to this:
routes.MapRoute(
"Default", // Route name
"{action}/{id}", // URL with parameters
new { controller = "Controller", action = "Action", id = UrlParameter.Optional } // Parameter defaults
);
I'm trying to start a mvc3 website. But when I load the server I get this error.
Description: HTTP 404. The resource you are looking for (or one of its
dependencies) could have been removed, had its name changed, or is
temporarily unavailable. Please review the following URL and make
sure that it is spelled correctly.
My routes file looks like this
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = "" } // Parameter defaults
);
routes.MapRoute(
"States", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "States", action = "Index", id = "" } // Parameter defaults
);
}
I noted that you have two possibly conflicting route registrations. Try removing the first registration and leaving only this one:
routes.MapRoute(
"States",
"{controller}/{action}/{id}",
new { controller = "States", action = "Index", id = "" }
);
Could someone show me how to use the MapRoute method? I have tried creating my own routes, but it's not working. What i want to accomplish is a route that routes "http://servername/home/default.aspx" into controller "Home" and action "Default". Also, would it be possible to say that if the user is browsing the default.aspx "file", it would actually point to the "Index" action?
I have tried reading the MSDN references and googling, but it didn't make me any wiser.
Probably too late to help the developer who raised the question but may help someone else. New to MVC but what I found is the map routes seem to be processed in the order they are added. I had a similar problem, my specific route was not working until I started adding the default route as the last route.
If the default map route is added before your custom one and your custom URL matches the structure defined by the default map route you will never reach your custom route.
The route you want to configure the first part of your question is:
routes.MapRoute(
"",
"home/default.aspx",
new { controller = "Home", action = "Default" }
);
Assuming you wish to 'browse' default.aspx with some sort of parameter you can do something like:
routes.MapRoute(
"",
"home/default.aspx/{param}",
new { controller = "Home", action = "Default", param = UrlParameter.Optional }
);
And you would then need to create your Default action to accept string param.
You also have to make sure the parameter name is the same as the action's parameter name.
Example:
routes.MapRoute(
name: "MyName",
url: "{controller}/{action}/{myParam}",
defaults: new { controller = "MyController", action = "MyAction", id = UrlParameter.Optional }
);
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
MyController:
public ActionResult MyAction(string myParam = "")
{
}
