C# – ASP.Net MVC route mapping

asp.netasp.net-mvccrouting

I'm new to MVC (and ASP.Net routing). I'm trying to map *.aspx to a controller called PageController.

routes.MapRoute(
   "Page",
   "{name}.aspx",
   new { controller = "Page", action = "Index", id = "" }
);

Wouldn't the code above map *.aspx to PageController? When I run this and type in any .aspx page I get the following error:

The controller for path '/Page.aspx' could not be found or it does not implement the IController interface.
Parameter name: controllerType

Is there something I'm not doing here?

I just answered my own question. I had the routes backwards (Default was above page).

Yeah, you have to put all custom routes above the Default route.

So this brings up the next question... how does the "Default" route match (I assume they use regular expressions here) the "Page" route?

The Default route matches based on what we call Convention over Configuration. Scott Guthrie explains it well in his first blog post on ASP.NET MVC. I recommend that you read through it and also his other posts. Keep in mind that these were posted based on the first CTP and the framework has changed. You can also find web cast on ASP.NET MVC on the asp.net site by Scott Hanselman.

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
