C# – Grouping controllers in Asp.NET MVC

asp.netasp.net-mvcc

I would like to create a sub folder in the controllers folder of an Asp.Net MVC application. But when ever I do this and try to navigate to a page the controller can not be found.

Here's a concrete example.
Currently I have:

Controlers/UserAdminControler.cs
Controlers/PageAdminControler.cs
Controlers/MenuAdminControler.cs
Controlers/SomeOtherControler.cs
...

I want to organize it like this:

Controlers/Admin/UserAdminControler.cs
Controlers/Admin/PageAdminControler.cs
Controlers/Admin/MenuAdminControler.cs
Controlers/SomeOtherControler.cs
...

I found a way to create "Areas." This is a really nice idea and article but that is not really what I am looking for my site:

As well I have found that you can create sub folders in the Views directory (when you return View() you simply supply the path as a parameter). All I need now is to figure out how to add sub folders in the controllers directory.

I just tried it, with no issues. I added a sub folder in my Controllers direcotry, and called it "SubFolder". There I added a Controller called "SubController". I then added a Folder in my views called Sub and added a View called Index. I then ran the app and navigated to:

http://localhost:2922/Sub/Index

with no problems. Maybe I'm misunderstanding your question, but there seems to be no issues with adding subfolders in the controllers folder.

Asp.net-mvc – Compile Views in ASP.NET MVC

From the readme word doc for RC1 (not indexed by google)

ASP.NET Compiler Post-Build Step

Currently, errors within a view file are not detected until run time. To let you detect these errors at compile time, ASP.NET MVC projects now include an MvcBuildViews property, which is disabled by default. To enable this property, open the project file and set the MvcBuildViews property to true, as shown in the following example:

<Project ToolsVersion="3.5" DefaultTargets="Build" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
  <PropertyGroup>
    <MvcBuildViews>true</MvcBuildViews>
  </PropertyGroup>

Note Enabling this feature adds some overhead to the build time.

You can update projects that were created with previous releases of MVC to include build-time validation of views by performing the following steps:

Open the project file in a text editor.
Add the following element under the top-most <PropertyGroup> element: <MvcBuildViews>true</MvcBuildViews>
At the end of the project file, uncomment the <Target Name="AfterBuild"> element and modify it to match the following:

<Target Name="AfterBuild" Condition="'$(MvcBuildViews)'=='true'">
    <AspNetCompiler VirtualPath="temp" PhysicalPath="$(ProjectDir)\..\$(ProjectName)" />
</Target>

C# – How to create a dropdownlist from an enum in ASP.NET MVC

For MVC v5.1 use Html.EnumDropDownListFor

@Html.EnumDropDownListFor(
    x => x.YourEnumField,
    "Select My Type", 
    new { @class = "form-control" })

For MVC v5 use EnumHelper

@Html.DropDownList("MyType", 
   EnumHelper.GetSelectList(typeof(MyType)) , 
   "Select My Type", 
   new { @class = "form-control" })

For MVC 5 and lower

I rolled Rune's answer into an extension method:

namespace MyApp.Common
{
    public static class MyExtensions{
        public static SelectList ToSelectList<TEnum>(this TEnum enumObj)
            where TEnum : struct, IComparable, IFormattable, IConvertible
        {
            var values = from TEnum e in Enum.GetValues(typeof(TEnum))
                select new { Id = e, Name = e.ToString() };
            return new SelectList(values, "Id", "Name", enumObj);
        }
    }
}

This allows you to write:

ViewData["taskStatus"] = task.Status.ToSelectList();

by using MyApp.Common
