C# - Viewengine Not Looking Into Areas For Views In Mvc3 Upgrade?
Mar 10, 2011
i'm upgrading my asp.net mvc app to the MVC 3 from mvc 2. I had everything set up so that there were no areas, but now i have to move the old application into its own area so i can start a new one. The new area is working great, but for some reason, when i try to go into the area where the old app was, it looks for the views to be in the views folder in the root of the app, instead of in the views folder in the area.

I have upgraded my MVC2 project to MVC3 project and now I want to change the viewengine from standard aspx to the Razor viewengine. I have tested to create a new MVC3 project with the Razor viewengine and this works just fine, but now I want to uppgrade my existing MVC3 aspx viewengine project to a project with the Razor viewengine.

I have upgraded my project from .NET 3.5 to 4.0 and my views will no longer compile.I have a data layer that is a Linq to SQL data context in an assembly.My problem is when I pass in an entity to the model of my view and then try an enumerate a property that is an entity set of foreign key values I get a compilation error ofThe type 'System.Data.Linq.EntitySet`1' is defined in an assembly that is not referenced. You must add a reference to assembly 'System.Data.Linq, Version=4.0.0.0, Culture=neutral,ublicKeyToken=b77a5c561934e089'.I have added a reference to the project for System.Data.Linq and I can enumerate the entity sets in my controllers, it is just when trying to do it in a view I get the issue.This works fine in a .NET 3.5 project and thought I may have upgraded incorrectly but I get the same issue if I start a new project from scratch.

Why are Razor views not generated as partial classes? Making them partial classes gives us the option to have a code behind where we can do some of the stuff we're forced to do in the template itself in the code behind file.
Yes, I know the standard "go-to" thing is Html helper but I don't want to use Html helpers for these things as they are too specific to the view in question and besides, having a clutter of extension methods is just not the way to go.
I'd like to see Razor views generated as partial classes.

I have a question about the MVC3 view page activator and how changes to the views trigger recompilation. There seems to be some magic going on in BuildManager that I can't see because the source code is not available for the symbols -- and even reflector can't see inside.
What I've done is implement my own VPP and subclass of the Razor view engine for purposes of displaying razor views that do not live on the filesystem. My mock setup just returns data from a string to render. This works fine, but what does not work is when you change that data, the class is not recompiled. And it is not clear how to get either RazorBuildProvider or BuildManager to regenerate the c# code and recompile it when the data returned from the VPP is different.

I am woking on a MVC project which require me to put all controllers, models and views into a folder called Mvc instead of the project root, I created a custom viewengine, here is the code:
[Code]....
My Application_Start:
[Code]....
It does not work, when I request [URL], I got: The view 'Index' or its master could not be found. The following locations were searched:
~/Mvc/Views/Index.aspx
~/Mvc/Views/Index.ascx
~/Mvc/Views/Shared/Index.aspx
~/Mvc/Views/Shared/Index.ascx
I expect the custom viewengine to find the view at: ~/Mvc/Views/Home/Index.aspx

The following code works for webform view engine.
<% Model.Categories.ForEach(x => { %>
<li><a href="#">@x.Name</a></li>
<% }) %>
I wrote the above code as below in razor view:
@Model.Categories.ForEach(x => {
<li><a href="#">@x.Name</a></li>
})
But this doesn't work. Is there any way to achieve this in razor view?

I've read about how I can create a custom viewengine however is it possible to load an assembly which has a method decorated by my own custom attribute say..[RenderWithView], then I dynamically invoke that method and apply a view engine to it, finally returning the html?

I were following the tutorial at this page of how to build my own view engine: [URL] And in hope of just extending the existing RazorViewEngine I made some changes to the code in the tutorial...
[Code]....
The thing is that now when I run my site..I get the following error: CS0246: The type or namespace name 'WebMatrix' could not be found (are you missing a using directive or an assembly reference?) and I just cant find a way to solve this..I have added the references.

I am using Actionfilter to globally filter our HTML comments from all action methods and in all controllers. It simply overrides OnActionExecuting and runs the response through a regex to filter the comments. I am also using RenderAction to render some more complicated widgets in my website. There is no caching in place, I just use Renderactionto keep my code as simple possible.
When calling RenderAction from within a Razor View, I get an error message telling me that "Filtering is not allowed". The problem does not occur when calling RenderAction from within an aspx View. It only occurs when calling RenderAction from within a Razor View. In case it matters: the view being rendered is implemented with ASPX. Is this a bug or a known limitation?

I have a Page.cshtml similar to the following (that does not work):
@{
Layout = "../Shared/Layouts/_Layout.cshtml";
var mycollection = (ViewBag.TheCollection as IQueryable<MyCollectionType>);
}
<h2>@ViewBag.Title</h2>
content here
@if (mycollection != null && mycollection.Count() > 0)
{
@section ContentRight
{
<h2>
Stuff
</h2>
<ul class="stuff">
@foreach (MyCollectionType item in mycollection )
{
<li class="stuff-item">@item.Name</li>
}
</ul>
}
}
As I said, this does not work. I want to not define the section if there's nothing in the collection. Is there any way to have something like this work? If not, what are my other options? I'm very new to this Razor ViewEngine. Edit In my layout i have:
@if(IsSectionDefined("ContentRight"))
{
<div class="right">
RenderSection("ContentRight")
</div>
}
what i don't want is the div to output when the section is empty.

I am following Chris Pietschmann's solution for theming in ASP.NET MVC.
One thing I have noticed is that the view name is not being retrieved from the ViewLocationCache on subsequent requests. I am using ASP.NET MVC 2.0 RC
When the following code is executed:
this.ViewLocationCache.InsertViewLocation(controllerContext.HttpContext, cacheKey, virtualPath);
and I hover over this.ViewLocationCache it just returns {System.Web.Mvc.NullViewLocationCache} - suggesting nothing was added?

I have an MVC view that contains a number of partial views. These partial views are populated using partial requests so the controller for the view itself doesn't pass any data to them. Is it possible to reload the data in one of those partial views if an action was triggered in another? For example, one partial view has a jqGrid and I want to refresh the data in another partial view when a user selects a new row in this grid. Is there a code example for this scenario (in C#) that I can look at to see what am I doing wrong? I am using ajax calls to trigger a new request but non of the partial views are refreshed so I am not sure if the issue is with the routing, the controller,

I'm following this blog post about setting up ELMAH with MVC: [URL] I've only done part 1. Everything works correctly if I simply go to the Home controller, and then cause an error. I can view /elmah.axd as well, and my errors are logging in the database correctly.
However, I've added an area to my application named Admin. If I navigate to /Admin, I receive the following error:
System.MissingMethodException: No parameterless constructor defined for this object.
public override IController CreateController(RequestContext requestContext, string controllerName)
{
var controller = base.CreateController(requestContext, controllerName); //Error here
var c = controller as Controller;
I'm assuming this has something to do with my Area.
EDIT for jfar:
For instance, I have an Employees controller in my Admin area:
public class EmployeesController : Controller
{
private IEmployeesRepository employeesRepository;
public EmployeesController(IEmployeesRepository employeesRepository)
{
this.employeesRepository = employeesRepository;
}
//...
}

To use separation of concern and to optimize the clearness of the controllers we decided to split each action of a controller into different controllers (FunctionalLocationEditController, FunctionalLocationCreateController and such).
Problem now is the Global.asax is currently a bit big for just a few pages registered in routes.
We would need to use an area type of mechanism but for business reason we are not ready to upgrade just yet to MVC2.
Basically, is there a way in MVC1 to map the Urls to something like <folder>/<controller>/<action> ?

Been starting a new project (MVC 2) based on the first version of the same application (MVC 1).In the first we breaked out Controllers and Views into seperate projects, which resuted in a clean and organized structure.Now with version 2, I've been reading about this "Areas".Keeping the old structure and using areas sounds like overkill to me. Keeping the old way OR use Areas is what I'm trying to decide on.Just wanted to hear your thoughts about this.... Is it really that usefull (ie have other benifits)? No use to make some major changes just because something is there IMHO

I'm starting a new ASP.NET MVC project, and I decided to put my controllers in a different assembly. Evertyhing works fine, but I have hit a problem: I created a new area in my MVC Project, called Administration. I have an AdminController Class in my seperate assembly which is supposed to return views from my Admin area, but everytime it tries to return a view, it looks for it in the wrong place (~/Admin/SomeView.cshtml Instead of ~/Administration/Admin/SomeView.cshtml) How can I tell the controller to look for views in the wanted area?

is there some way to share a partial razor view between areas? For example a login partial, it is found if i use @Html.Partial("_LoginPartial") but the URLs Html.ActionLink generates are local to the calling area (even though the partial itself is not part of the area).
_LoginPartial.cshtml is in /Views/Shared/_LoginPartial.cshtml
Calling view is inside /Areas/Somearea/Views
Links generated are like: [URL]
But should always be: [URL]
Partial view source:
@if(Request.IsAuthenticated) {
<text>Welcome <b>@Context.User.Identity.Name</b>!
[ @Html.ActionLink(@Messages.Logout, "Logout", "Account") ]</text>
}
else {
@:[ @Html.ActionLink(@Messages.Login, "Login", "Account") ]
}
