I have issue in Routing in Mvc 4
My url goes like this
http://localhost:portnumber/Session/View?Id=918&Pid=186
I want my url to be like this
http://localhost:portnumber/Session/View/918/186
I have view like this
#Html.RouteLink("more..", "Default", new {Controller="Session",Action="View",Id=e.Id,Pid=e.Pid })
routes.MapRoute(
name: "SessionView",
url: "{controller}/{action}/{Id}/{Pid}",
defaults: new { controller = "Session", action = "view", Id = UrlParameter.Optional, Pid = UrlParameter.Optional }
);
The problem is that you're not referring to the correct route.
In the routing table, you've added a route with the name "SessionView", but in your #Html.RouteLink, you refer to a route called "Default".
The correct call should be:
#Html.RouteLink("more..", "SessionView", new {Controller="Session",Action="View",Id=e.Id,Pid=e.Pid })
Just try this
#Html.ActionLink("more..", "View", "Session", new {Id=e.Id,Pid=e.Pid })
Description:
Html.ActionLink(<<LinkText>>,
"<<ActionMethod>>",
"<<Controller Name>>",
new { Id=e.Id,Pid=e.Pid }, // <-- Route arguments.
)

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
I want to implement a custom route in my MVC app and I just can't get it to work. I want to keep the exist default route as specified when you create your MVC app.
The routes I want to be valid should look like this:
default: /{controller}/{action}/{id}
new custom: /{controller}/{appid}/{action}/{id}
With the custom domain, I will be passing the appid in with every request, but the {id} should be optional. The routes are thus defined as follow:
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Updates", action = "Index", id = UrlParameter.Optional }
);
routes.MapRoute(
name: "NewPackageRoute",
url: "{controller}/{appid}/{action}/{id}",
defaults: new { controller = "apps", appid = "00000000000000000000", action = "Index", id = UrlParameter.Optional }
);
On the AppsController, I have an action method Index:
public ActionResult Index(string appid, string id)
If I supply the id parameter, this action method is hit as expected. I am expecting this method to also be called if the {id} parameter is not supplied, thus leaving the id parameter as null. This however does not happen.
How should I define my route differently? Should I perhaps rather make use of AttributeRouting for achieve my goal?
I should maybe also add... If I call the Search action on the Apps controller, I can get to the action. This would happen through the default route...
Hope I have all and enough info...
Oh my, but I guess I should've tried before I posted this. I left this issue for a day and now I got it working without any effort...
Thanks #StephenMuecke. You did point out the ordering of the routes which I forgot about. I played with the order initially, but at that point I had other issues in the route definitions that caused it not to work.
All I added was as length check on the appid route value and it is working... My routes are defined as follow now:
routes.MapRoute(
name: "NewPackageRoute",
url: "apps/{appid}/{action}/{id}",
defaults: new { controller = "Apps", action = "Index", id = UrlParameter.Optional },
constraints: new { appid = #"^[a-zA-Z0-9]{20}" }
);
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Updates", action = "Index", id = UrlParameter.Optional }
);
I'm having trouble doing what I want to achieve when doing routing in ASP.NET MVC.
What I want to do is the following:
When typing http://localhost/MyWebsite/, I want to redirect to http://localhost/MyWebsite/Login/ (The redirection to the action Index is implied here)
When typing http://localhost/MyWebsite/MyAction, I want to redirect to http://localhost/MyWebsite/Login/MyAction
Point 1 was achieved using the following lines in the file RouteConfig.cs:
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Login", action = "Index", id = UrlParameter.Optional });
But I cannot accomplish point 2. Note that the user does not come from another action in a controller, but actually types the address in his browser.
Thanks for your help.
since /MyWebsite/Login and /MyWebsite/MyAction both have two segments in the URL, they're both matching your defined Route.
You can use a Route Constraint to only match /MyWebsite/Login to your first point, followed by a modified second route mapping:
routes.MapRoute(
name: "Default",
url: "MyWebsite/Login/",
defaults: new { controller = "Login", action = "Index", id = UrlParameter.Optional });
routes.MapRoute(
name: "Actions",
url: "MyWebsite/{action}/",
defaults: new { controller = "Login", 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 made a change to my routing map which is following now:
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}/{title}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional, title = UrlParameter.Optional }
);
And this is the actionlinks that are not working anymore:
#Html.ActionLink("Category", "CategoryList", "Category")
When I click on this actionlink nothing happens the url stays the same http://localhost:62394/ as the page reloads. its so weird
and when I check the html it looks like this:
Category
Any kind of help or tips is appreciate alot!
note: If I remove title from the routing it works...
It's because you've got 2 optional parameters so the routing engine doesn't know which one to map the third parameter to. It feels like title is going to be used for a specific route rather than a generic one. If that's the case, why not create a specific route for it and remove it from the generic fallback route?
Something like this:
routes.MapRoute(
name: "Title",
url: "Category-List/{title}",
defaults: new { controller = "Category", action = "CategoryList", title = UrlParameter.Optional }
);
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
