I am having a problem where I try to open my ASP.NET MVC application but I get the ASP.NET error page which says this:
Server Error in '/' Application.
The resource cannot be found.
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.
Requested URL: /EventScheduler/account.aspx/login
Version Information: Microsoft .NET Framework Version:2.0.50727.3053; ASP.NET Version:2.0.50727.3053**
I am using the URL trick from this blog post and that is why I have the .aspx in the URL:
http://blog.codeville.net/2008/07/04/options-for-deploying-aspnet-mvc-to-iis-6/
It works on my other sandbox server (not a dev machine), and now I just deployed it to my production site as a new virtual directory, but for some reason it seems like it's actually looking for a .aspx file.
Any ideas? I think I must be forgetting a step.
I got the same error when building. The default is to use URLRoute settings for navigating. If you select the "Set as Startup Page" property by right clicking any cshtml page, that throws this error because there are always a routing to the current page under the Global.asax file.
Look at Project Properties for Startup Path and delete it.
I found the solution for this problem, you don't have to delete the global.asax, as it contains some valuable info for your proyect to run smoothly, instead have a look at your controller's name, in my case, my controller was named something as MyController.cs and in the global.asax it's trying to reference a Home Controller.
Look for this lines in the global asax
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = UrlParameter.Optional }
in my case i had to get like this to work
new { controller = "My", action = "Index", id = UrlParameter.Optional }
Make sure you're not telling IIS to check and see if a file exists before serving it up. This one has bitten me a couple times. Do the following:
Open IIS manager. Right click on your MVC website and click properties. Open the Virtual Directory tab. Click the Configuration... button. Under Wildcard application maps, make sure you have a mapping to c:\windows\microsoft.net\framework\v2.0.50727\aspnet_isapi.dll. MAKE SURE "Verify the file exists" IS NOT CHECKED!
You should carefully review your Route Values.
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = UrlParameter.Optional }
In this case, ensure you have your Controller 'Home' as the application will fail to load if there is no HomeController with Index Action. In My case I had HomesController and I missed the 's' infront of the Home. I Fixed the Name mismatch and this resolved the issue on both my local environment and on my server.
If you're running IIS 6 and above, make sure the application pool your MVC app. is using is set to Integrated Managed Pipeline Mode. I had mine set to Classic by mistake and the same error occurred.
The page is not found cause the associated controller doesn't exit. Just create the specific Controller. If you try to show the home page, and use Visual Studio 2015, follow this steps:
Right click on Controller folder, and then select Add > Controller;
Select MVC 5 Controller - Empty;
Click in Add;
Put HomeController for the controller name;
Build the project and after Run your project again
I hope this help
Two Things Needs To Be Ensure:
1) Route should be proper in Global.ascx file
2) Don't forget to add reference of Controller Project in your Web Project (view is in separate project from controller)
The second one is my case.
Had the same issue, in my case the cause was that the web.config file was missing in the virtual dir folder.
I got the same error while building a MVC application.
In my case it happened because I forgot to add the string "Controller" in my controller name.
Error With
public class ProductType : BaseController
{
public ProductType()
{
}
}
Resolved
public class ProductTypeController : BaseController
{
public ProductTypeController ()
{
}
}
In your Project open Global.asax.cs then right click on Method RouteConfig.RegisterRoutes(RouteTable.Routes); then click Go To Definition
then at defaults: new { controller = "Home", action = "Index", id =UrlParameter.Optional}
then change then Names of "Home" to your own controller Name and Index to your own View Name if you have changed the Names other then "HomeController" and "Index"
Hope your Problem will be Solved.
Step 1 : Check to see if you have received the following update? http://support.microsoft.com/kb/894670 If you have you might want to follow this procedure and see if it works for you. It worked partially for me.
The item where it mentions the additional "/" to be removed is not entirely true but it did give me some insight to change my project properties just a bit.
step 2 : Right click on your properties for your Web Project in your Solun.
Select WEB > Choose Current Page instead of Specific Page.
step 3 : Go into your project where you keep your *.aspx's select a start page. (Should be the same as the current page or choose another one of your choice :) )
Hit Debug Run.
Suppose source code copy from other places.
Sometime, if you use Virtual Directory in your application url like:
http://localhost:50385/myapp/#/
No route will pick up the request.
solution:
Explicitly click the button 'create a virtual directory' in your project file.
Go to any page you want to see it in browser right click--> view in browser.
this way working with me.
Upon hours of debugging, it was just an c# error in my html view.
Check your view and track down any error
Don't comment c# code using html style ie
Open your Controller.cs file and near your public ActionResult Index(), in place of Index write the name of your page you want to run in the browser. For me it was public ActionResult Login().
Remember to use PUBLIC for ActionResult:
public ActionResult Details(int id)
{
return View();
}
instead of
ActionResult Details(int id)
{
return View();
}
you must check if you implemented the page in the controller
for example:
public ActionResult Register()
{
return View();
}
I had a similar problem. But I was working with Episerver locally with ssl enabled. When I wasn't getting a
Server Error in '/' Application.
I was getting a Insecure connection error.
In the end, for me, this post on PluralSight together with configuring the website urls, accordingly with the ssl link set up on the project's config, on Admin's Manage Website's screen solved the problem.
In my case, I needed to replace this:
#Html.ActionLink("Return license", "Licenses_Revoke", "Licenses", new { id = userLicense.Id }, null)
With this:
Return license
<script type="text/javascript">
function returnLicense(e) {
e.preventDefault();
$.post('#Url.Action("Licenses_Revoke", "Licenses", new { id = Model.Customer.AspNetUser.UserLicenses.First().Id })', getAntiForgery())
.done(function (res) {
window.location.reload();
});
}
</script>
Even if I don't understand why. Suggestions are welcome!
For me its solved follow the following steps :
One reason for this occur is if you don't have a start page or wrong start page set under your web project's properties. So do this:
1- Right click on your MVC project
2- Choose "Properties"
3- Select the "Web" tab
4- Select "Specific Page"
Assuming you have a controller called HomeController and an action method called Index, enter "home/index" in to the text box corresponding to the "Specific Page" radio button.
Now, if you launch your web application, it will take you to the view rendered by the HomeController's Index action method.
It needs you to add a Web Form, just go to add on properties -> new item -> Web Form. Then wen you run it, it will work. Simple
I had the same problem caused by my script below. The problem was caused by url variable. When I added http://|web server name|/|application name| in front of /Reports/ReportPage.aspx ... it started to work.
<script>
$(document).ready(function () {
DisplayReport();
});
function DisplayReport() {
var url = '/Reports/ReportPage.aspx?ReportName=AssignmentReport';
if (url === '')
return;
var myFrame = document.getElementById('frmReportViewer');
if (myFrame !== null) {
if (myFrame.contentWindow !== null && myFrame.contentWindow.location !== null) {
myFrame.contentWindow.location = url;
}
else {
myFrame.setAttribute('src', url);
}
}
}
</script>
I can't find out how to solve this. I have two URLs. These are /my-url-1 and /my-url-2. Both going to different views.
The thing is that I have an ActionLink on /my-url-1's view which should make /my-url-2 and go to that view.
The problem is that ActionLink makes /my-url-1/my-url-2 as the URL and not just /my-url-2.
I was searching two days about how to fix it but couldn't find anything.
PD: I'm not using Areas so please don't tell me that I just should put the "area" parameter as a "".
These are two urls which goes to different controllers and different actions.
View which has the ActionLink (URL:/my-url-1) :
<div class="btn-index-container">
#Html.ActionLink("Url 2", "MyAction", "MyController")
</div>
This ActionLink should render:
Url 2
But it's rendering:
Url 2
where /my-url-1 is my current URL
Route Config
routes.MapRoute(
name: "route1",
url: "my-url-2", //without parameters
defaults: new { controller = "MyController", action = "MyAction" },
);
routes.MapRoute(
name: "route2",
url: "my-url-1", //without parameters too
defaults: new { controller = "MyController2", action = "MyAction2" }
);
So, when I go to localhost:port/my-url-1 it loads MyAction2 which renders a view. This view has inside an ActionLink(described above) which should render a /my-url-2 link.
Well, I've worked inside the MVC framework and I could told you about how Url.RouteUrl or Html.RouteLink works. At the end, the method which create the URL is GetVirtualPathForArea (this method is called before UrlUtil.GenerateClientUrl, which receive the VirtualPathData.cs created by GetVirtualPathForArea, as a parameter) from System.Web.Routing.RouteCollection.cs.
Here I left a link to the MVC source code:
https://github.com/aspnet/AspNetWebStack/blob/master/src/System.Web.Mvc
I found that, my Request.ApplicationPath was changing when I loaded /my-url-1. It was crazy because the application path was /.
At last, the problem was that the /my-url-1 was pointing to a virtual directory created on the IIS some time ago by error.
To know where your IIS configuration file is, please follow the link below:
remove virtual directory in IIS Express created in error
The solution was remove the .vs directory (which contains the config .vs\config\applicationhost.config) and rebuild
I think most of the Helpers that render URLs works more or less in the same way, so I hope it'll useful for all of you!
In your case, maybe no its necesary, just pass the parameters with null values, E.G.
#Html.ActionLink("Español", null, null, new { Lng = "es" }, null)
In this way, the parameters change, and the view is relative, depending on where you are.
This is a very strange problem. I am new to the mvc world coming from web forms and i am trying to understand its concepts. Using the MVC template in vs 2013 (premium), I have built a project. In order to see how things work:
I create a new controller 'IndexController' and put it in the folder .../Controllers/IndexController.cs
I create a new View for this controller 'Index.cshtml' and put it in the corresponding folder: .../Views/Index/[#] Index.cshtml
Then I change the routing so that the default routing will now point to this IndexController and not to the default HomeController
Here is my routing table:
public class RouteConfig
{
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Index", action = "GetIndexPage", id = UrlParameter.Optional }
);
}
}
You can see that I am using 'GetIndexPage' as the default action instead of 'Index' (I'm playing around and see how it works)
Whenerver I make a change in the Index.cshtml (say I add a simple markup and hit 'Run' I always receive the error message
Server Error in '/' Application. The resource cannot be found.
Looking at the address bar I see that the browser is looking for the resource 'localhost:xxx/Index/Index' instead of 'localhost:xxx/Index/GetIndexPage'. To solve this problem, I go in the IndexController and put a breakpoint inthe line
return View(...);
Now I hit 'Run', after stopping at the breakpoint, every thing works perfectly. So it is not a problem of routing since the page is displayed after this breakpoint trick. Visual Studio seems to mess up with the deployment to the IIS Express I am using after I have made a change to the cshtml view. The problem does not occur when I make a change in the code behind of the controller. I don't know where to look at...I have spent this whole night trying to find a solution in Google and stackoverflow...I don't want to reinstall the whole visual studio. Any help, any hint to a certain direction will be greatly appreciated.
After a lot of trials I discover that mvc framework wants the action and the view (that this action returns) must have the same name. In my case this is what has worked:
route configuration:
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Index", action = "IndexPage", id = UrlParameter.Optional }
);
IndexController:
public class IndexController : Controller
{
public ActionResult IndexPage()
{
return View();
}
}
You can see that route action has same name with method of controller: IndexPage
And finally create a view with name IndexPage.cshtml
With this configuration when I make a change in the cshtml file it is immediately reflected in the browser and there is not the error reported above.
I just want to have a confirmation if this is indeed the way things must be set up with the mvc approach. (thanks with your help)
Strange problem I got here. I using Visual Studio 2012. When I start debugging my web application from .cshtml tabs I getting this error
Server Error in '/' Application. The resource cannot be found.
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.
Requested URL: /Views/Header/GeneralInputs.cshtml
Version Information: Microsoft .NET Framework Version:4.0.30319;
ASP.NET Version:4.0.30319.225
When I run it from .cs tabs everything is fine and runs well. Whats wrong?
Here's my RouteConfig
public class RouteConfig
{
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Header", action = "GeneralInputs", id = UrlParameter.Optional }
);
}
}
Also I tried to adding this line into the WebConfig, but that didn't help
<modules runAllManagedModulesForAllRequests="true" />
UPD:
what I got in
HeaderController
public ActionResult GeneralInputs()
{
return View();
}
I think you can't request this page like this:Requested URL/Views/Header/GeneralInputs.cshtml. You should request Header/GeneralInputs. You must request the Action in the controller. No the view in the controller
The feature you are seeing can actually be quite useful: directly run the page (Controller/Action) your cursor is in.
But when you frequently call this from a View, or from Actions that require parameters, you can fix your starting point from Project|Properties|Web, and then check the (o) Specific Page option.
The action name "GeneralInputs" should be in your HeaderController and GeneralInputs.cshtml file should be in Header View folder. if both are well and good. Then don't run your application while the cursor in GeneralInputs.cshtml page. Keep the cursor in the controller then run your application.
I am currently working in a brownfield ASP.NET MVC 3 project in VS2010.
In this project, views and controllers are in separate projects. This is not something that I have seen before. In each action method there is no explicit stating of view name as below.
return View("viewName",passingModel);//projects where controllers and views are in same
I have done this implicitly in VS2012 by right clicking on the view and do add view. So I was not bothered about where is this connection between action method's return view and the view is stated.
Unlike in VS2012, in VS2010 I can not navigate to the view that is related to one particular action method by right clicking on View and doing go to view.
I tried to understand this by doing this small experiment. I created a Controller and created a Action Method call xxxx and I created a view for that implicitly as mentioned above and searched the word xxxx in entire solution but this word only appeared in controller and in the view.
So, I was unsuccessful in finding the answer. I think visual studio itself creating its own mapping to achieve this.
I would like to know who these implicit connections are created among action methods and views to understand what is going on in my project.
Edit:
Both the projects which contains controllers and views are class libraries. not asp.net mvc projects.
Global.aspx file contains this:
public static void RegisterGlobalFilters(GlobalFilterCollection filters)
{
filters.Add(new HandleErrorAttribute());
}
protected void Application_Start()
{
DependenciesHelper.Register(new HttpContextWrapper(Context));
AreaRegistration.RegisterAllAreas();
RegisterGlobalFilters(GlobalFilters.Filters);
RoutingHelper.RegisterRoutes(RouteTable.Routes);
}
protected void Application_End()
{
//Should close the index
//If this method is not executed, the search engine will still work.
SearchService.CloseIndex();
}
The mapping is fairly straightforward. For example if you have a controller called "MyBrilliantController" and an action method called "MyExcellentAction" which returned just return View(); it would map to (in the UI project) ~/Views/MyBrilliant/MyExcellentAction.cshtml
The only time where this is different is when you are working with "Areas" - but the mapping is effectively the same, it would just consider the area folder first (ie ~/Areas/MyArea/Views/MyBrilliant/MyExcellentAction.cshtml)
Hope that helps.
EDIT - You can also specify namespaces in the global.asax file on each route for the engine to find controllers
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
new string[] {
// namespaces in which to find controllers for this route
"MySolution.MyControllersLib1.Helpers",
"MySolution.MyControllersLib2.Helpers",
"MySolution.MyControllersLib3.Helpers"
}
);
}
