Hy
i had write below code
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
"Home", // Route name
"", // URL with parameters
new { controller = "Home", action = "Index" } // Parameter defaults
);
routes.MapRoute(
"Controller_Action", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { id = UrlParameter.Optional } // Parameter defaults
);
foreach (var route in GetDefaultRoutes())
{
routes.Add(route);
}
routes.MapRoute(
"UserPage", // Route name
"{id}", // URL with parameters
new { controller = "Home", action = "Get" } // Parameter defaults
);
}
private static IEnumerable<Route> GetDefaultRoutes()
{
//My controllers assembly (can be get also by name)
Assembly assembly = typeof(test1.Controllers.HomeController).Assembly;
// get all the controllers that are public and not abstract
var types = assembly.GetTypes().Where(t => t.IsSubclassOf(typeof(Controller)) && t.IsPublic && !t.IsAbstract);
// run for each controller type
foreach (var type in types)
{
//Get the controller name - each controller should end with the word Controller
string controller = type.Name.Substring(0, type.Name.IndexOf("Controller"));
// create the default
RouteValueDictionary routeDictionary = new RouteValueDictionary
{
{"controller", controller}, // the controller name
{"action", "index"} // the default method
};
yield return new Route(controller, routeDictionary, new MvcRouteHandler());
}
}
i am new to mvc,i want to rewrite my url somthing like this,suppose my url is like www.myhouse.com/product/index/1 then i want to display only www.myhouse.com/prduct-name for better seo performance,i am using mvc4 beta,i had also one through URL Rewriting in .Net MVC but it is not working for me....
but i don't know how to pass pass value to this method.
After lots of searching on the internet, i got my solution
add below code to global.asax
routes.MapRoute(
"Home", // Route name
"", // URL with parameters
new { controller = "Home", action = "Index" } // Parameter defaults
);
routes.MapRoute(
"jats", // Route name
"{jats}", // URL with parameters
new { controller = "Home", action = "Content" } // Parameter defaults
);
then add below code to view:
#Html.ActionLink("test", "Content", new { jats= "test-test" })
add below code to HomeController:
public ActionResult Content(string jats)
{
return View();
}
then you done...now URL is same as you pass in query string...so your controller name and query string parameter will not display.

The below link gives be the following url: http://localhost:11111/files/Details/3
#Html.ActionLink("Details", "Details", "mycontroller", new { id = item.id },null)
But I'm trying to have a url parameter like this http://localhost:11111/files/Details?id=3 or http://localhost:11111/files/Details.aspx?id=3
How do I get the actionlink to show the url like details?i=3
Here is my controller View:
public ActionResult Details(int? id)
{
...
return View();
}
Why would you like to see the parameter's name in the link?
Asp.Net MVC uses user-friendly URLs.
If you have created a project in Visual Studio using the MVC template, probally your routes, by default, are configured to interpret the parameter after the controller/action/ like the id.
So the id parameter's value in your action will be automatically replaced, by model binding, with the id number present in you URL.
The routing codes can be found under the RegisterRoutes method in the Global.asax file of our project.
I see a cookie already in the RegisterRoutes method.
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = "" } // Parameter defaults);
Using the MapRoute method above, we defined a new route.
Sample ;
public class HaberController : Controller
{
public ActionResult Listele()
{
// Listing codes will be written
return View("Listele");
}
public ActionResult Detay(string HaberId)
{
// Detail codes will be written
return View("Detay");
}
}
We go to our Global.asax file and edit it as follows.
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
"HaberListeleme",
"Haber",
new { controller = "Haber", action = "Listele" }
);
routes.MapRoute(
"HaberDetay",
"Haber/{id}",
new { controller = "Haber", action = "Detay" }
);
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = "" } // Parameter defaults
);
}
If we do the routing as follows:
routes.MapRoute(
"HaberDetay",
"Haber/{*Id}",
new { controller = "Haber", action = "Detay" }
);
So if we write * by putting the character next to our parameter name, it will be sent to the related parameter of the Detail method in the Controller, no matter what it says after the News / url tab.
For example:
http://www.doguhanaydeniz.com/Haber/Turkiye/Guncel/34389
If a URL is requested as Turkey / current / 34389 will be sent as a parameter.
I have setup my routes so that I have the following flat URL structure:
mywebsite/service-option-one (goes to Home Controller, Option1 action)
mywebsite/service-option-two (goes to Home Controller, Option2 action)
mywebsite/ (goes to Home Controller, Index)
mywebsite/about (goes to Home Controller, Index with path=about)
mywebsite/contact (goes to Home Controller, Index with path=contact)
This is important as I have a lot of content views and do not want to have individual actions for these generic information pages, the simple code for the resolving the view is at the end of this post.
When building the menu the MVC Html.ActionLink helpers, but they give the incorrect addresses for generic content which makes sense as these actions do not exist!
Given my address scheme, how can is there a helper method I can use to set my anchor link targets or do i just have to resort to hard coding in html (i.e. <a href="~/contact>Contact us</a>)?
// note that the order of the routes is very important!
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
// error route
routes.MapRoute(
"Error", // Route name
"Oops", // URL with parameters
new { controller = "Home", action = "Error" }
);
routes.MapRoute(
"Service1",
"service-option-one",
new { controller = "Home", action = "Option1" }
);
routes.MapRoute(
"Service2",
"service-option-two",
new { controller = "Home", action = "Option1" }
);
// default home controller route for general site content (/content), uses default path value set to Index
routes.MapRoute(
name: "Catchall",
url: "{path}",
defaults: new { controller = "Home", action = "Index", path = "Index" }
);
// home page route, blank url (/)
routes.MapRoute(
"HomePage", // Route name
"", // URL with parameters
new { controller = "Home", action = "Index" }
);
// default route
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "{controller}", action = "{action}", id = UrlParameter.Optional } // Parameter defaults
);
}
public class HomeController : Controller
{
private bool ViewExists(string name)
{
ViewEngineResult result = ViewEngines.Engines.FindView(ControllerContext, name, null);
return (result.View != null);
}
public ActionResult Index(string path)
{
System.Diagnostics.Debug.WriteLine("looking for..." + path);
if (ViewExists(path)==true)
{
System.Diagnostics.Debug.WriteLine("general controller action...");
return View(path);
}
else
{
System.Diagnostics.Debug.WriteLine("page not found...");
return RedirectToRoute("Error");
}
}
public ActionResult Error()
{
return View();
}
public ActionResult Option1()
{
return View();
}
public ActionResult Option2()
{
return View();
}
}
You're approaching the use of the ActionLink helper from the opposite position that you should be when using helpers. You're trying to tell Razor what the routed url should be for the link, when in reality that's what Razor is going to be doing for YOU. So for the example of mywebsite/service-option-one, the only place you should have service-option-one written down is in your routes map. In your views, you should be doing
#Html.ActionLink("The Anchor Text You Want To Display","Option1","Home")
Then when Razor renders the view, it will translate to
The Anchor Text You Want To Display

I have this route map defined.
routes.MapRoute("default", // route name
"{controller}/{action}/{id}", // url with parameters
new { controller = "home", action = "index", id = UrlParameter.Optional }, // parameter defaults
new string[] { "mobilesurveys.mt.controllers" }
);
This will work perfectly. now I want to add another routemap
routes.MapRoute("couponreedem", // route name
"{controller}/{action}/{clientname}", // url with parameters
new { controller = "Rc", action = "index", id = UrlParameter.Optional }, // parameter defaults
new string[] { "mobilesurveys.mt.controllers" }
);
i have defined like this. Here Rc is my controller. and I am giving the url as
.com /Rc/Rc/sammy
and method in the controller defined as
public ActionResult Rc(string clientname)
{
viewModel =dataRc.ProductCategoryGet();
return View(viewModel);
}
clientname will be always null. How to add another route while the existing route not be disturbed.
Thanks.
It actually looks identical. But in case you want a new one you can try something like this, and it should be above the default one.
routes.MapRoute("couponreedem", // route name
"RC/{action}/{clientname}", // url with parameters
new { controller = "Rc", action = "index", clientname = UrlParameter.Optional }, // parameter defaults
new string[] { "mobilesurveys.mt.controllers" }
);
That will fix the route with RC/...
Also your action should be named Index
public ActionResult Index (string clientname)
{
viewModel =dataRc.ProductCategoryGet();
return View(viewModel);
}
I'm kind of new to MVC. I have a controller called PostItemsController in an area called CaseManagers with an action method called GetByUmi(int caseNumber):
[HttpGet]
public ViewResult ViewByUmi(int umi)
{
//implementation omitted
}
The routing configuration looks like this (not my work):
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.IgnoreRoute("{resource}.aspx/{*pathInfo}");
//ignore route for ico files
routes.IgnoreRoute("{*favicon}", new { favicon = #"(.*/)?../Images/MauriceFavicon.ico(/.*)?" });
routes.IgnoreRoute("{*favicon}", new { favicon = #"(.*/)?Images/MauriceFavicon.ico(/.*)?" });
routes.IgnoreRoute("{*favicon}", new { favicon = #"(.*/)?Content/Images/MauriceFavicon.ico(/.*)?" });
routes.IgnoreRoute("{*favicon}", new { favicon = #"(.*/)?/favicon.ico(/.*)?" });
//ignore javascript files routing
routes.IgnoreRoute("{file}.js");
//ignore routing for files ending .doc
routes.IgnoreRoute("{resource}.doc");
routes.MapRoute(
"CaseManagers", // Route name
"CaseManagers/PostItems/ViewByUmi/{id}", // URL with parameters
new { controller = "PostItems" } // Parameter defaults
);
//InvoicesLookUp route
routes.MapRoute(
"InvoicesLookUpShortDefault", // Route name
"InvoicesLookUp/{action}/{id}", // URL with parameters
new { controller = "InvoicesLookUp", action = "Index", area = "Home", id = UrlParameter.Optional } // Parameter defaults
,
null,
new[] { "MooseMvc.Areas.Accounts.Controllers" } // Parameter defaults
).DataTokens.Add("area", "Accounts");
//Invoices route
routes.MapRoute(
"InvoicesShortDefault", // Route name
"Invoices/{action}/{id}", // URL with parameters
new { controller = "Invoices", action = "Index", area = "Accounts", id = UrlParameter.Optional } // Parameter defaults
,
null,
new[] { "MooseMvc.Areas.Accounts.Controllers" } // Parameter defaults
).DataTokens.Add("area", "Accounts");
//administrating route
routes.MapRoute(
"AdministratorShortDefault", // Route name
"Administrator/{action}/{id}", // URL with parameters
new { controller = "Administrator", action = "Index", area = "Administrator", id = UrlParameter.Optional } // Parameter defaults
);
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults
);
//add root route route
routes.MapRoute(
"Root",
"",
new { controller = "Home", action = "Index", id = "" }
);
When I try to call this method with the URL http://localhost:[portnumber]/CaseManagers/PostItems/ViewByUmi/1234 I get the following exception:
The parameters dictionary contains a null entry for parameter 'umi' of non-nullable type 'System.Int32' for method 'System.Web.Mvc.ViewResult ViewByUmi(Int32)' in 'MooseMvc.Areas.CaseManagers.Controllers.PostItemsController'. An optional parameter must be a reference type, a nullable type, or be declared as an optional parameter.
Parameter name: parameters
I don't intend the ID parameter to be optional and I don't understand why MVC can't find the ID.
Can anyone tell me what I need to do?
EDIT:
Phil Haack's route tester is telling me that the following route is being mapped:
routes.MapRoute(
"CaseManagers", // Route name
"CaseManagers/PostItems/ViewByUmi/{id}", // URL with parameters
new { controller = "PostItems" } // Parameter defaults
);
But it is being mapped AFTER another route CaseManagers/{controller}/{action}/{id}. But this route isn't anywhere in the Global.asax file (take a look, it's reproduced in full above).
Any idea what's going on?
Method parameters in ASP.NET MVC match up 1-1 with route parameters. Since you have no routes that take in a route value named umi, no route will catch what you're trying to do.
You have one of two choices:
If you want the default route to handle that action, then change:
public ViewResult ViewByUmi(int umi)
{
//implementation omitted
}
to:
public ViewResult ViewByUmi(int id)
{
//implementation omitted
}
However, if you want to keep umi(because it has contextual meaning that makes that code easier to follow), then you want to add a route to explicitly deal with it:
//UMI route
routes.MapRoute(
"umi",
"/case/postitems/view/{umi}",
new { area = "CaseManager", controller = "PostItems", action = "ViewByUmi", umi = "" }
);
Turns out that Global.asax isn't the only place that routing happens. Each of the areas in this application has its AreaRegistration class. I added a new route to the top of this class to produce the following:
public class CaseManagersAreaRegistration : AreaRegistration
{
public override string AreaName
{
get
{
return "CaseManagers";
}
}
public override void RegisterArea(AreaRegistrationContext context)
{
context.MapRoute(
"PostItems", // Route name
"CaseManagers/PostItems/ViewByUmi/{umi}", // URL with parameters
new { area = "CaseManagers", controller = "PostItems", action = "GetByUmi", umi = "{umi}" } // Parameter defaults
);
context.MapRoute(
"CaseManagers_default",
"CaseManagers/{controller}/{action}/{id}",
new { action = "Index", id = UrlParameter.Optional }
);
}
}
The routing debugger now tells me this is getting matched first. Now I just need to work out why I've got an error telling the the resource cannot be found...
You don't have a route for CaseManagers/PostItems/ViewByUmi/1234 and it would appear that it is taking ViewByUmi and try to convert it to an System.Int32 because it is falling into the Default route. If you create a Route for your CaseManagers you should no longer have this problem.
Use Phil Haacks' Route Debugger to help you out :o)
routes.MapRoute(
"CaseManagers", // Route name
"CaseManagers/PostItems/ViewByUmi/{id}", // URL with parameters
new { controller = "PostItems" } // Parameter defaults
);
I'm learning about creating custom routes in ASP.NET MVC and have hit a brick wall. In my Global.asax.cs file, I've added the following:
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
);
// My Custom Route.
routes.MapRoute(
"User_Filter",
"home/filter/{name}",
new { controller = "Home", action = "Filter", name = String.Empty }
);
}
The idea is for me to able to navigate to http://localhost:123/home/filter/mynameparam. Here is my controller:
public class HomeController : Controller
{
public ActionResult Index()
{
return View();
}
public ActionResult Filter(string name)
{
return this.Content(String.Format("You found me {0}", name));
}
}
When I navigate to http://localhost:123/home/filter/mynameparam the contoller method Filter is called, but the parameter name is always null.
Could someone give a pointer as to the correct way for me to build my custom route, so that it passes the name part in the url into the name parameter for Filter().
The Default route should be the last one.
Try it this way:
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
// My Custom Route.
routes.MapRoute(
"User_Filter",
"home/filter/{name}",
new { controller = "Home", action = "Filter", name = String.Empty }
);
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults
);
}
I believe your routes need to be the other way round?
The routes are processed in order, so if the first (default, OOTB) route matches the URL, that's the one that'll be used.
