Asp.net-mvc – How to route legacy QueryString parameters in ASP.Net MVC 3

asp.net-mvcasp.net-mvc-3

I am using a third party service that does an async callback to a URL I provide to them.
So I tell them to use http://www.mysite.com/Status/Incoming.
This must obviously map to an Incoming() method on my StatusController.

However, what I don't have control over is the format of the parameters they call my URL with.
E.g. They will do a callback such as: http://www.mysite.com/Status/Incoming?param1=val1&param2=val2&param3=val3

I want to map this to the parameters of my action method: Incoming(string param1, string param2, int param3)

How do I do this?

I have found a lot of stuff about custom routing, but nothing about legacy QueryString parameters.

Best Answer

There is no such thing as legacy query string parameters. There are query string parameters and they are part of the HTTP specification. And assuming that the http://www.mysite.com/Status/Incoming?param1=val1&param2=val2&param3=val3 url is called you don't need any route to make it map to the following action (the default route will do just fine):

public ActionResult Incoming(string param1, string param2, string param3)
{
    ...
}

The default model will take care of binding those values.

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
