I have this route map (notice that topicName is ignored):
routes.MapRoute(
"Topics", // Route name
"Topic/{topicName}/{action}",
new { controller = "Topic", action = "AddQuestion" });
And I want it to defaultly map to this Url:
http://localhost:51421/Topic/SomeName/AddQuestion?topicId=1 (or if that's not possible,to this url: http://localhost:51421/Topic/SomeName/AddQuestion/topicId/1)
(which should invoke this action:
public ActionResult AddQuestion(int topicId)
{
return View();
}
)
But either way I need all this data in the url.
What's the correct way to do that?
You could add a default route:
routes.MapRoute(
"Topics",
"Topic/{topicName}/{action}/{topicId}",
new { controller = "Topic", action = "AddQuestion", topicId = "1" }
);
routes.MapRoute(
"Default",
"{controller}/{action}/{topicId}",
new { controller = "Topic", action = "AddQuestion", topicId = "1" }
);

I´m trying to get full URL but the RouteUrl is returning empty.
In the View, I´m calling like that:
alert('#Url.RouteUrl("Api", new { controller = "Parametros", id = "" })');
Here is my routes configurations:
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapHttpRoute(
name: "Api",
routeTemplate: "api/{controller}/{id}",
defaults: new { id = RouteParameter.Optional }
);
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Usuario",
action = "Login", id = UrlParameter.Optional }
);
}
and my controller:
public class ParametrosController : ApiController
{
ISistemaService _sistemaService;
public ParametrosController(Empresa empresa, ISistemaService sistemaService)
{
_sistemaService = sistemaService;
}
public PagedDataModel<ParametroDTO> Get(
[FromUri]ParametroFiltro filter, int page, int pageSize)
{
int total = 0;
var list = _sistemaService.Paging(filter, page, pageSize, out total);
return new PagedDataModel<ParametroDTO>(page, pageSize, total, list);
}
public ParametroDTO Get(string codigo)
{
return _sistemaService.GetParametroPorCodigo(codigo);
}
}
Add httproute = "" to the routeValues:
alert('#Url.RouteUrl("Api",
new { httproute = "", controller = "Parametros", id = "" })');
I have a route that is defined like this:
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = UrlParameter.Optional, area = "" }, // Parameter defaults
new { home = new HomePageConstraint() }
);
public class HomePageConstraint : IRouteConstraint
{
public bool Match(HttpContextBase httpContext, Route route, string parameterName, RouteValueDictionary values, RouteDirection routeDirection)
{
return !httpContext.Request.RawUrl.StartsWith("/home", StringComparison.InvariantCultureIgnoreCase);
}
}
And I am trying to test it like this:
[Test]
public void Home_Load_Homepage()
{
"~/".ShouldMapTo<HomeController>(x => x.Index());
}
The problem I have is that the httpContext is null, so the test fails. how can I inject http context into a constraint?
In the end I did this:
var context = new FakeHttpContext("~/");
var fakeRequest = new FakeRequest("~/", new Uri("http://localhost/"), new Uri("http://localhost/"));
context.SetRequest(fakeRequest);
var route = RouteTable.Routes.GetRouteData(context);
route.ShouldMapTo<HomeController>(x => x.Index());
Here is my desired url format: /product-24-hid-35wh4-cx-dsgtx
How can I map this URL to my action method:
public ActionResult Product(int id)
Here is my routing code:
routes.MapRoute(
"ProductDetail",
"product-{id}-{name}",
new { controller = "product", action = "detail", name = UrlParameter.Optional },
new string[] { "SphereLight.Controllers" }
);
However, it does not work; I used phil haack's routedebugger to test this route, and below is the result:
Key Value
name dsgtx
id 24-hid-35wh4-cx
controller product
action detail
Only id = 24 is correct.
In one word, I need a route to match:
/product-24
/product-24-
/product-24-hid-35wh4-cx-dsgtx
Try to add constraints in your MapRoute:
routes.MapRoute(
"ProductDetail",
"product-{id}-{name}",
new { controller = "product", action = "detail", name = UrlParameter.Optional },
new { id = #"\d+" }, // <-- change it for #"[^-]+", if it can be non-digit
new string[] { "SphereLight.Controllers" }
);
UPDATE:
Finally got it.
The main problem is that you can't use parameters which contains the same separator.
For example, the example above will work with /product-24-nm, but not with product-24-nm-smth.
So, let's try this solution:
I've made it on the default routing, you can make it your way
routes.MapRoute(
"Default",
"{controller}/{action}/{id}",
new { controller = "Home", action = "Index", id = UrlParameter.Optional },
new MyRouteHandler()
).RouteHandler = new MyRouteHandler();
Implementation of MyRouteHandler:
public class MyRouteHandler : MvcRouteHandler
{
private static readonly Regex ProductPattern = new Regex(#"product\-(\d+)\-?(.*)");
protected override IHttpHandler GetHttpHandler(RequestContext requestContext)
{
var match = ProductPattern.Match(requestContext.RouteData.Values["controller"].ToString());
if (match.Length > 0)
{
requestContext.RouteData.Values["controller"] = "Home";
requestContext.RouteData.Values["action"] = "Detail";
requestContext.RouteData.Values["id"] = match.Groups[1].Value;
requestContext.RouteData.Values["name"] = match.Groups[2].Value;
}
return base.GetHttpHandler(requestContext);
}
}
So, the main idea is to check if the values matches our pattern product-id-name in the handler, and not trying to make it in MapRoute.
Hope this helps.
I am start to learn the MVC3, But i have some problem on WebGrid,
The Controller name is TestController, so i navigate to :
http://localhost:53503/Test/
And the Webgrid shown as below:
two column : ID and Name.
the 3rd & 4th column : Actionlink and item.GetSelectLink.
The first problem is :
Assume i viewing page 3 of webgrid, and press the ActionLink,after go-thought the TestContoller's Action, the webgrid will return to page 1 after PostBack.
However,if i press the [View(GetSelectLink)] on right end:
(e.g. http://localhost:53503/Test/?gridItems_page=3&gridItems_selectedRow=3
It works.
So, i should use ActionLink or GetSelectLink for general Add/Update/Delete operation?
MVC3 hasn't viewstate / control state, so how can i preserve the current page selection after PostBack?
The second problem is :
The (href) of ActionLink is :
http://localhost:53503/Test/GetSelection/7?Name=PSP
I would make it to
http://localhost:53503/Test/GetSelection/7/PSP
I add a new route to global.asax, but it is no luck.
Thanks you very much for help.
It is my code:
Views/Test/Index.cshtml
#model List<MvcContract.Controllers.Products>
#{
System.Web.Helpers.WebGrid grid = new System.Web.Helpers.WebGrid(
source: Model,
canPage: true,
rowsPerPage: 3,
fieldNamePrefix: "gridItems_",
pageFieldName: "page",
selectionFieldName: "selectedRow"
);
}
#{
if (Model != null)
{
#grid.GetHtml(
columns: grid.Columns(
grid.Column("ID"),
grid.Column("Name"),
grid.Column(format: (item) => Html.ActionLink("View(ActionLink)", "GetSelection", new { ID = item.ID, Name = item.Name })),
grid.Column(format: (item) => item.GetSelectLink("View(GetSelectLink)"))
)
);
}
}
Controllers/TestController.cs
namespace MvcContract.Controllers
{
public class Products
{
public string ID { get; set; }
public string Name { get; set; }
public List<Products> GetItems()
{
List<Products> items = new List<Products>();
items.Add(new Products() { ID = "1", Name = "PS3" });
items.Add(new Products() { ID = "2", Name = "XBox360" });
items.Add(new Products() { ID = "3", Name = "Wii" });
items.Add(new Products() { ID = "4", Name = "Saturn" });
items.Add(new Products() { ID = "5", Name = "Dreamcast" });
items.Add(new Products() { ID = "6", Name = "NDS" });
items.Add(new Products() { ID = "7", Name = "PSP" });
items.Add(new Products() { ID = "8", Name = "NeoGeo" });
items.Add(new Products() { ID = "9", Name = "3DO" });
items.Add(new Products() { ID = "10", Name = "Playdia" });
return items;
}
}
public class TestController : Controller
{
//Bind data to WebGrid
public ActionResult Index()
{
Products products = new Products();
return View(products.GetItems());
}
//Some Logic
public ActionResult GetSelection(string ID, string Name)
{
string SelectedID = ID;
return RedirectToAction("Index");
}
}
}
RegisterRoutes() in Global.asax.cs
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 = UrlParameter.Optional } // Parameter defaults
);
routes.MapRoute(
"Test_GetSelection", // Route name
"{controller}/{action}/{id}/{name}", // URL with parameters
new { controller = "Test", action = "GetSelection", id = UrlParameter.Optional, name = UrlParameter.Optional } // Parameter defaults
);
}
Check out this discussion. I think one of several solutions there may solve your issue.
Since its been a whole year since you posted this, please post an answer if you figured it out another way.
I've created a custom Route and registered it in Global.asax like this:
routes.Add(
null,
new SeoRoute(
"foo/{id}/{title}",
new { controller = "Foo", action = "Details" }
));
Since I'm using Areas in my application, I have to set Namespaces for each Route.
With regular routes, I do it like this:
routes.MapRoute(
null,
"foo",
new { controller = "Foo", action = "Index" },
new string[] { "Boo.Web.Controllers" }
);
But how can I set namespaces for custom routes?
Any help would be greatly appreciated!
I used ILSpy too see how MapRoute works.
I didn't set DataTokens value. Here's the solution:
Route class:
public class SeoRoute : Route
{
public SeoRoute(string url, object defaultValues, string[] namespaces)
: base(url, new RouteValueDictionary(defaultValues), new MvcRouteHandler())
{
if(namespaces != null && namespaces.Length > 0)
{
DataTokens = new RouteValueDictionary();
DataTokens["Namespaces"] = namespaces;
}
}
...
}
Global.asax:
routes.Add(
null,
new SeoRoute(
"foo/{id}/{title}",
new { controller = "Foo", action = "Details" },
new string[] { "Boo.Web.Controllers" }
));
