In my MVC 2 (RC) I do not see the Codebehind files, Have they been deliberately remvoed ?
If you had a proper install of MVC 1, the codebehind files would already be gone. They are sometimes considered harmfull as they are likely to violate the MVC pattern.
Codebehind is still possible though, yet you'll need to add them by hand. See f.e. how to add a code-behind page to a view or partial view.
The closest thing to codebehind in MVC would be the controller, although it's not really comparable since the controller have no clue of whats going on in the view.

I am working on an existing Asp.net MVC 4 project and I want to know if there is any way to check in solution explorer that if view is partial or not. Please suggest.
Partials often have an underscore prefix in their name. Other than that, nothing really separates them from other views.
i want to integrate mvc2 into an existing webforms project. to get this work, i found all information online.
now i have the problem that mvc just works when the controller and views folder are placed in the root, but i want to have a specific folder (like 'mvc') so that the controller and views folder are placed like this:
~/mvc/controller
~/mvc/views
is this possible or do i have to use mvc area to solve this issue?!
thanks for your help!
best regards...
If you want to group all of your MVC work together, I would use areas to accomplish this.
I think it is possible though to override the View Engine to point the default root to a different folder. This is detailed in this post.
Something to think about before doing this though is, are you planning to eventually migrate your WebForms to Asp.net MVC and remove your WebForms work? If so you might be better keeping the root Controllers and Views folders in the project root.
Here is what I want to achieve, I want to separate AREAs of ASP.NET MVC as pure single DLL.
Blog.DLL
Forums.DLL
FAQ.DLL
Each of them are individual ASP.NET MVC Area, with its own default CSHTML or ASPX pages. Installing, migrating and maintaining lots of pages including resources, javascripts and so on are real pain for long run. As most of these will hardly change.
My final website will be like this.
\MvcApplication
\bin
\MvcApplication.bin
\Blog.dll
\Forums.dll
\Controllers
\..
\Models
\..
\Views
\..
\Global.asax
\Web.config
Without adding any thing, just dropping Blog.dll, my application should support /blog and all its pages. If I want to customize something, than I can add area, and add only cshtml pages..
\MvcApplication
\bin
\MvcApplication.bin
\Blog.dll
\Forums.dll
\Areas
\Blog
\Views
\Shared
\BlogLayout.cshtml <-- this will override the look
\Controllers
\..
\Models
\..
\Views
\..
\Global.asax
\Web.config
This will help in reusing ASP.NET Area Plugins, by simply dropping the dll in bin folder. However web.config may require some changes, but most likely we will save configure values in database and only thing needed will be "Entity Framework connection string" in web.config.
My challenges (Questions)
Is it possible? It sure looks to me, but will there be any reflection/permission issues?
How do I include cshtml/aspx views within one DLL? Probably compiled versions? I have seen couple of text template based View Engines on codeplex but I am little confused on how to actually use them.
And how do I get ViewEngine to first check if physical directory file exists or not and then look into cshtml/aspx within the dll itself as resource file?
You may take a look at the following article which illustrates how a custom VirtualPathProvider could be used in order to retrieve Razor views that are embedded into separate assemblies as resources.
Maybe worth looking at portable areas from mvccontrib. I haven't used them since MVC 2, but found the following SO question by someone having some problems using them with MVC 3, with some possible solutions: ASP.NET MVC 3, Razor Views, and Portable Areas
MvcCodeRouting supports what you want, plus many other cool stuff. Check out this post about ASP.NET MVC Plugins.
Can I upgrade my MVC2 project to MVC3 and continue to use my ASPX views, AND at the same time start writing some new views in Razor?
More specifically, Can I take an ASPX view page, and a Razor control in it? Would such a thing be possible?
Any other things one should look out for?
You can definitely mix view engines across totally separate views. As for putting Razor "controls" in an ASPX page, if you use RenderPartial, it should work.
One thing I would watch out for is that if you use Master Pages then you may end up duplicating them for both view engines. I had a good ol' WebForms Master Page, used by all my regular .aspx content files, but creating a new view using Razor means I have to use a duplicate Razor layout page alongside that old Master Page.
I haven't looked into it too much, but at first try I get 'The file "~/Views/Shared/Site.Master" could not be rendered, because it does not exist or is not a valid page.' and certainly there's nothing in Scott Gu's blog entry introducing Razor to suggest you can combine them, but I could be all wrong here.

For how to mix view engine master pages...
Trying to create a MVC User Control in the Release Candidate and I can't see to make one with a codebehind file. The same is true for MVC View pages.
Creating Views in the Beta would produce codebehinds...am I missing something?
Code behind kind of defeats the purpose of the MVC Framework. Functionality should be kept separate from the view, the MVC team felt that code behind pages went against this ideology and therefore removed them.
Your can create a custom helper method to create your control. Also I'm not sure if MVC has view components (Monorail/Castle) but that could be an option as well.
From ScottGu's Blog post:
*Views without Code-Behind Files
Based on feedback we’ve changed view-templates to not have a code-behind file by default. This change helps reinforce the purpose of views in a MVC application (which are intended to be purely about rendering and to not contain any non-rendering related code), and for most people eliminates unused files in the project.
The RC build now adds C# and VB syntax support for inheriting view templates from base classes that use generics. For example, below we are using this with the Edit.aspx view template – whose “inherits” attribute derives from the ViewPage type:
One nice benefit of not using a code-behind file is that you'll now get immediate intellisense within view template files when you add them to the project. With previous builds you had to do a build/compile immediately after creating a view in order to get code intellisense within it. The RC makes the workflow of adding and immediately editing a view compile-free and much more seamless.
Important: If you are upgrading a ASP.NET MVC project that was created with an earlier build make sure to follow the steps in the release notes – the web.config file under the \Views directory needs to be updated with some settings in order for the above generics based syntax to work.*
I answered this question here:
How to add a Code-behind page to a Partial View
Seems this wasn't particularly tricky, and is quite do-able
This answer worked for a Partial 'ViewUserControl' but the same should apply
Ok.
First: Add a Class file with the convention of .cs (i.e. view.ascx.cs)
Second: Add "using System.Web.Mvc;" to the class
Third: Change the Class to Inherit from "ViewUserControl<>"
Fourth: Add the following to the View's header:
CodeBehind="View.ascx.cs" Inherits="Project.Views.Shared.View"
Fifthly: Copy the files out of the solution and drag back in to reassociate the two together
Note: For this to work with a Normal MVC View you just need to inherit the class from "ViewPage"
The whole idea for ASP.Net-mvc was to get rid of the codebehind files...thats why asp web controls didnt matter that most didn't work.But with the changes of getting rid of the code behind comes with a different programming style..The idea is codebehind files are EVIL:
http://stevesmithblog.com/blog/codebehind-files-in-asp-net-mvc-are-evil/
the whole idea is to make sure people remember they are using asp.Net-mvc and not asp.et web pages. take alook at this link ,it explains it a little better:

I think this tutorial is what you are asking.. but not really sure what you want..
