This is my route registration code:
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
"course_list",
"course/list",
new { controller = "course", action = "list" }
);
routes.MapRoute(
"course_view",
"course/view/{id}",
new { controller = "course", action = "list", id = UrlParameter.Optional }
);
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
I have a link /course/view/87
And the route that is matched is /course/list
Can anyone explain why?
Thank you
UPDATE:
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
"course_list",
"course/list",
new { controller = "course", action = "list" }
);
routes.MapRoute(
"course_view",
"course/view/{id}",
new { controller = "course", action = "view", id = UrlParameter.Optional }
);
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
But I'm still getting the same issue.
When i visit: /course/view/87 i get a 404 error.
It appears that your route for course/view/{Id} has a 'list' action. I expect this is a typo.
Adding these routes to an empty Asp.Net Mvc 4 project and using routedebugger (http://nuget.org/packages/routedebugger/), I get a Matched Route of "course/view/{id}". You should use routedebugger locally to see what is going on. The above code seems to be fine.
The button element is treated as submit button (i.e.: type="submit" if not default type attribute is set). Therefore, the browser initiated a post request, which no route satisfied, since all my actions are get(s).
Thank you all for your time.

In my MVC application's RouteConfig I am using this:
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
routes.MapRoute (
name: "Dictionary", // Route name
url: "dictionary/{id}", // URL with parameters
defaults: new { controller = "Dictionary", action = "details" } // Defaults
);
At this time this URL succeeds in returning a page:
http://127.0.0.1:8080/dictionary/details/1
Whereas this fails:
http://127.0.0.1:8080/dictionary/1
With the exception
"HTTP 404.The resource you are looking for (or one of its dependencies) could have been removed, had its name changed..."
When I swap the routing around, like this:
routes.MapRoute (
name: "Dictionary", // Route name
url: "dictionary/{id}", // URL with parameters
defaults: new { controller = "Dictionary", action = "details" } // Defaults
);
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
It both URLs start returning a page.
Why is this?
Thanks in advance.
FYI This question is different to the possible duplicate because of the UrlParameter.Optional and the wild carded routing in the other question. This question is more about which specific ordering is correct and why.
The order of the routes that you add to the route table is important. If you reversed the order, then the Default route always will get called instead of the custom route.
Reference:
https://www.asp.net/mvc/overview/older-versions-1/controllers-and-routing/creating-custom-routes-cs
Let say I have a website www.example.com
the default routing looks like
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Login", action = "Index", id = UrlParameter.Optional }
);
Ok that works fine but let's say I want my site when I go to www.example.com/id to go to www.example.com/login/index/id
How would I configure/add routing for this, without breaking my other pages where I am actually trying to go to www.example.com/controller?
EDIT: Unfortunately id is a string so I do not have any concrete constraints that I can think of that would work. Think of maybe instead of the id I should have said companyname or sitename so the URL would look like www.example.com/companyname .
The only solution that I have come up with so far is adding a maproute for each one of my controllers like this
routes.MapRoute(
name: "Home",
url: "Home/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
routes.MapRoute(
name: "Settings",
url: "Settings/{action}/{id}",
defaults: new { controller = "Settings", action = "Index", id = UrlParameter.Optional }
);
routes.MapRoute(
name: "companyname",
url: "{id}",
defaults: new { controller = "Login", action = "Index", id = UrlParameter.Optional }
);
routes.MapRoute(
name: "default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Login", action = "Index", id = UrlParameter.Optional }
);
This will work but I have many controllers and if I add one in the future and forget to adjust the routes it will fail. Also, this is unlikely but if a companyname happens to the be same as one of my controller names it would also fail.
In controller you may redirect to another Controller/action:
public ActionResult yourAction()
{
return RedirectToAction("nameAction","nameController");
}
Did you tried adding this mapping first:
routes.MapRoute( name: "Custom", url: "{id}", defaults: new { controller = "Login", action = "Index", id = UrlParameter.Optional } );
That should work but keep in mind that routes are evaluated secuentially, so you will have to organize mappings in order to reach out all pages in your site.
For example, routes like www.example.com/Product could be redirected to /Login by mistake.
EDIT: You can add constraints, so if id is an int value, you can try with the following:
routes.MapRoute("Custom", "{id}",
new { controller = "Login", action = "Index" },
new { id = #"\d+" }
EDIT 2: Having ids as string values, the only solution I see is to manually add each controller as you said, or to add something like this:
routes.MapRoute(
name: "Default",
url: "app/{controller}/{action}/{id}",
defaults: new { controller = "Login", action = "Index", id = UrlParameter.Optional }
);
This way you don't need to update each route in the future.
Please try below routing
routes.MapRoute(name: "companylogin", url: "companylogin/{id}", defaults: new
{
controller = "Login",
action = "Index",
id = UrlParameter.Optional
});
routes.MapRoute(name: "default", url: "{controller}/{action}/{id}", defaults: new
{
controller = "Login",
action = "Index",
id = UrlParameter.Optional
});
Remove other controller specific routing. Now you can navigate to login using
url : - www.example.com/companylogin/{id} and all other url redirect default route.
Hi I have a URL as follows in my MVC 4 application
http://localhost/ABC/Home/DeleteApp/3000
and I have configured RouteConfig.cs as follows
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
It goes to the Correct DeleteApp Controller but with the ID value Null. It shows the correct URL when I enable firebug.
What could possibly go wrong?
it debugs and come to here but the id field as null;
public void DeleteApp(string id)
{
try
{
// delete logic
}
catch (Exception e)
{
//
}
}
Possibles causes :
-> Check your "id" variable name (must be exactly the same name in the RouteConfig and in the controller action, it is case sensitive)
-> You have other routes mapped before this one that match the pattern
If you have a route mapped as {controller}/{action}/{something} and another route mapped as {controller}/{action}/{something_else}, when you call the url "Home/DeleteApp/3000", it can't tell if 3000 is "something" or "something_else" so it will take the first match.
To make this working, you have to use "Route Constraints"
http://www.codeproject.com/Articles/641783/Customizing-Routes-in-ASP-NET-MVC
You need to do it like so:
routes.MapRoute(
name: "ABC",
url: "ABC/{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
If you want to have url in this format http://localhost/ABC then you will have to modify the route as below by adding ABC to {controller}/{action}/{id} expression.
routes.MapRoute(
name: "Default",
url: "ABC/{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
I want users to be able to access the "/Linecard" page of my ASP.Net MVC site using "/Linecard" or "/Manufacturers" as the URL... so same controller, 2 different possible URLs.
I tried adding the following:
routes.MapRoute(
name: "Manufacturers",
url: "Manufacturers/{action}/{id}",
defaults: new { controller = "Linecard", action = "Index", id = UrlParameter.Optional }
);
Adding this after the "Default" route doesn't work at all and I get a 404 error when I go to "/Manufacturers". Putting it BEFORE "Default" works, but then only "/Manufacturers" shows up in the URL when I click menu links since it is the first match. I would like "/Linecard" to always show as the URL.
Any pointers? Is there a certain constraint I can use to accomplish this? Thanks!
I had the same problem when we moved to extension-less URLs. We needed to continue to support one route with extensions. I got around it by having my default route apply to everything except the old URL, then after that mapping one specifically for the exception
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = UrlParameter.Optional },
// if controller specified does not match 'manufacturers' (case insensitive)
new { controller = "^((?i)(?!manufacturers).)*$" },
new string[] { "Namespace.Of.Controllers" }
);
routes.MapRoute(
"Manufacturers", // Route name
"Manufacturers/{action}/{id}", // URL with parameters
new { controller = "Linecard", action = "Index", id = UrlParameter.Optional },
new string[] { "Namespace.Of.Controllers" }
);
You could also set an order when mapping your routes with the defaults at the end like so
routes.MapRoute(
name: "Manufacturers",
url: "Manufacturers/{action}/{id}",
defaults: new { controller = "Linecard", action = "Index", id = UrlParameter.Optional }
);
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults
);
I have the following route:
routes.MapRoute(
name: "Default",
url: "home/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
This works fine and directs to the home controller Index action where the user enters /home
Is there a way that I can ALWAYS make it direct to the Index action if the user enters:
/home/xxx or
/home/xxx/xxx
Where xxx can be anything?
Sure, just remove the {action} part from your route definition so that the action is always Index:
routes.MapRoute(
name: "Default",
url: "home/{anything}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
If you remove the {action} from the url and keep it as a default value then it should work fine.
routes.MapRoute(
name: "Default",
url: "home/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
In this scenario action will ALWAYS be Index...
Try this to catch every possible route:
routes.MapRoute(
"Default",
"home/{*url}",
new { controller = "Home", action = "Index", id = UrlParameter.Optional } }
);
