C# – ASP.NET MVC 3 routing

asp.net-mvcasp.net-mvc-3asp.net-mvc-routingcnet

i am trying to create route.

Which is

/emlak/TITLE/number.aspx

such as

/emlak/Here_is_your_best_property/123456.aspx

Global.asax:

routes.MapRoute(
    "Product",
    "{controller}/{deli}/{productId}",
    new { controller = "emlak", action = "Index" },
    new { productId = UrlParameter.Optional , deli = UrlParameter.Optional  }
);

My controller

namespace emrex.Controllers
{
    public class EmlakController : Controller
    {
        //
        // GET: /Emlak/

        public ActionResult Index(String productId, String deli)
        {
            return View();
        }

    }
}

and i am getting next error:

Server Error in '/' Application.

The resource cannot be found.

Thanks for help.

Don't provide URL parameter defaults as constraints (as you did)

When you define your route as (I added additional comments so we know what each part is)

routes.MapRoute(
    // route name
    "Product",

    // Route URL definition
    "{controller}/{deli}/{productId}",

    // route values defaults
    new { controller = "emlak", action = "Index" },

    // route values constraints
    new { productId = UrlParameter.Optional , deli = UrlParameter.Optional  }
);

So basically you shouldn't provide constraints in your case which makes it meaningless. Put the last two in route defaults and keep constraints out of this route defintion as:

routes.MapRoute(
    "Product",
    "{controller}/{deli}/{productId}",
    new {
        controller = "Emlak",
        action = "Index",
        productId = UrlParameter.Optional,
        deli = UrlParameter.Optional
    }
);

This should definitely work unless you have some other route definitions or don't use code that you provided.

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
