I have a master.cshtml with a navigation bar. My first link is to another view, ProjectManagement
<li>Project Management</li>
master.cshtml is in /Views/Shared/_master.cshtml
ProjectManagement is in /Views/ProjectManagement.cshtml
Whenever I click on the link I get:
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/ProjectManagement.cshtml
Am I using the wrong path or should I try to access the page differently?
Edit: I was able to get close by using this:
<a href="#Html.Action( "ProjectMgmt", "Service", "Project Management" )">
The only problem is that it now puts the page into my navigation bar! I only want it to link to page, what could I be doing this time?
You don't link to directly to views, you link to actions. Actions are implemented as methods on a controller; these methods are located using the routing system.
Example Controller:
public class ServicesController : Controller
{
[HttpGet]
public ActionResult ProjectManagement()
{
// automatically locates the correct view; you can also explicitly
// pass the path to the view
return View();
}
}
You can now right-click on the action method name ("ProjectManagement") and select "Add View". This will help you create a new view, and put it in a location which can be automatically found by the view engine.
Views are typically placed in a "Views/[ControllerName]/" folder, e.g. "Views/Services/ProjectManagement.cshtml".
To link to this action method in your navigation bar, you can use the helper method ActionLink().
<li>#Html.ActionLink( "Project Management", "ProjectManagement", "Services" )</li>

I have simple tree structure in SilverStripe.
ParentPage and ChildPage.
On ParentPage I display the list of ChildPages. But I don't want to make accessible url:
/parent-page/child-page
I want to allow only
/parent-page
That's why I did redirect in ChildPage index action to ParentPage:
class ChildPage_Controller extends Page_Controller
{
public function index()
{
$this->redirect('/parent-page/');
}
}
It works well on frontend. But in CMS after I click to ChidPage in tree, it redirects me editing the ParentPage. (not to frontend url but to admin/pages/edit/show/ParentPageID ). This happen only in Split or Preview mode.
Can you advice how to prevent it? Or is there some other option? Thanks!
In the init function you can check if the user has permission to view the CMS and if the page currently has the stage get variable set:
class ChildPage_Controller extends Page_Controller {
public function init() {
parent::init();
if (!($this->getRequest()->getVar('stage') && Permission::check('VIEW_CMS'))) {
return $this->redirect($this->Parent()->Link(), 301);
}
}
}
This way a normal user will be redirected and a CMS user that isn't viewing the page with ?stage=... set will be redirected. The preview / split panes always set the stage get variable so the page will never be redirected when viewed in the preview / split pane.
so finally I found the solution.
Preview pane is displayed in an iframe. And parent CMS frame binds for changing the url of preview pane. It's because when you click to some link in preview pane, CMS navigates you to edit that page. So also when I do the redirect from ChildPage to ParentPage, the CMS pane catches the change of url and editor is redirected to the ParentPage.
I haven't found the way, how to prevent it, finally I needed to edit javascript of CMS (LeftAndMain.Preview.js line 251).
iframe.bind('load', function() {
self._adjustIframeForPreview();
// Load edit view for new page, but only if the preview is activated at the moment.
// This avoids e.g. force-redirections of the edit view on RedirectorPage instances.
// self._loadCurrentPage();
$(this).removeClass('loading');
});
So I commented out this line "self._loadCurrentPage();"
In the comment was written "This avoids e.g. force-redirections of the edit view on RedirectorPage instances." But it did the redirect anyway.
Maybe there's better way how to do that, but I haven't found it.
I've seen several MVC4 tutorials that show how to access the index URL for a view, but I can't seem to reach a new view that I add.
I can access my home index at:
http://localhost:3214/
But if I create a new view (let's call it "NewView.cshtml") I can't access it from
http://localhost:3214/NewView.cshtml
Where would it be?
The page inspector expects the page to be at:
http://localhost:4244/Home/NewView
But it isn't there.
UPDATE:
In the solution explorer the file is located at:
MyProject/Views/Home/NewView.cshtml
OK - So think of your Views as merely html files (although they are not) - i.e. they are purely for display purposes. But they are not static like normal HTMLs - they have code.
Hence its the controller and the route that you need to understand.
The route is what you type in the browser. For instance /Home/NewView will be translated to HomeController, NewView action if thats how you have configured it. The default view is {controller}/{action}/{id} so try http://localhost:4244/Home/NewView/1
Now to properly display and code NewView you need to go to your HomeController and add a NewView action. Like:
public ActionResult NewView()
{
return View(); // This will automatically display the NewView.chtml view from the Home (or Shared) folder in your Views folder
}
Then go to your Routes (typically in your global.asax file and add it like:
routes.MapRoute(
"SomeUniqueRouteName",
"Home/NewView",
new { controller = "Home" action = "NewView" }
);
Then you can call it like http://localhost:4244/Home/NewView without the id cause you haev specified a route for it.
Let me know if you need any more help.
I am having problem invoking my Log-on action method, which is in a controller outside current Area.
I get the following error message :
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.
Is any way of calling the root controller that is outside areas in the main controller folder ?
If you are in an area, you'll need to specify a blank one to access your root controllers.
#Html.ActionLink("Back to Home Controller", "Index", "Home", new { area = "" }, null)
You can pass Area in route parameters to ActionLink and other methods.
I'm very new to ASP.NET MVC and this is probably a really obvious thing...Basically, I can't access the "Forum" view which I had created inside "Home" folder (because I need a link to Forum on my main homepage.). I was wondering if it's okay to just move the Forum view into the Shared folder?
Is this somehow very bad practice? It seems like I have strong coupling now, because on the one hand the forum view gets called inside HomeController, and on the other hand it will pretty much always
be used with ForumController from now on. So that might be unnecessary/wrong somehow?
edit: If I do this, the URLs change in a weird way, there must be a better solution right?
First when I click on forum link on main page, I'm at: /Home/Forum. I look at the forum, everything is fine.
Now I click on "Post a topic", and after the roundtrip I'm at /Forum/PostTopic. Home is gone.
If you have a ForumController its associated views need to be located at ~/Views/Forum.
For example:
public class ForumController: Controller
{
public ActionResult Index()
{
return View();
}
}
and then you would have the corresponding view in ~/Views/Forum/Index.cshtml:
#{
ViewBag.Title = "Forum";
}
<h2>Forum</h2>
<p>
Put content here.
</p>
and finally you generate a link to the Index action of the ForumController like this:
#Html.ActionLink("Go to forum", "Index", "Forum")
I know this is probably straight forward, but this isnt working for me, I want to simply connect this to trigger a viewController when I click it. When I create a controller and a view and click it it throws a 404 and the code never hits the controller.
<div> All Accounts In the System</div>
You should probably follow few tutorials for mvc. Links are by default using System.Web.Routing magic (if you have default template, look into global.asax). Default url looks like /controller/action/id where id is optional, action defaulted to Index and controller defaulted to Home. For link construction in views use these helper methods:
#Html.ActionLink("All accounts in the system", "AdminReports", "Admin");
or
All accounts in the system
The link should look like /Admin/AdminReports with default settings.
You want something like this:
<a href='<%= Url.Action("Controller", "Action") %>'>Text</a>
where
Controller = Your controller name.
Action = Your action method.
