Asp.net-mvc – How to set up a route for the home page of an ASP.NET MVC site

asp.net-mvcrouting

I'm working with an ASP.NET MVC site which will use a CMS controller for all pages of the site except for the home page. Here's the idea:

Home controller:

www.site.com
www.site.com/default.aspx

CMS Controller:

www.site.com/about
www.site.com/agenda/schedule
www.site.com/monkey/eats/spaghetti
(pretty much anything else)

This page lists some options on how to set up a default page routing:

Leave Default.aspx unrouted and unredirected as the entry point to your application – with static links that take your users into the MVC portion of the app (or other static content).
Redirect Default.aspx in the code behind, either using the Page_Load event handler code, or use Response.Redirect("~/home") to send them to the Home controller (although this is a round-trip redirect).
Rename or delete Default.aspx. Despite the warning in the markup that says that default.aspx is required to ensure that ASP.NET MVC is activated by IIS when a user makes a "/" request… it's not actually needed in either the VS dev server, or IIS7. The default request will remain an application root request "/" and will be caught by the default route and sent to the home controller.

I guess one other option is to just use one controller with some logic that detects the home page case, but that seems to be fighting the concept.

How do you recommend setting up a specific route for the site home page?

www.site.com can be handled by an root map route

routes.MapRoute(
    "Root",
    "",
    new { controller = "Home", action = "Index", id = "" }
);

Put the following in page load of Default.aspx

HttpContext.Current.RewritePath(Request.ApplicationPath, false);
IHttpHandler httpHandler = new MvcHttpHandler();
httpHandler.ProcessRequest(HttpContext.Current);

This rewrites the request to root and handled by the map route above.

BTW, you can actually find the code from the MVC template project.

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

C# – How to handle multiple submit buttons in ASP.NET MVC Framework

Here is a mostly clean attribute-based solution to the multiple submit button issue based heavily on the post and comments from Maarten Balliauw.

[AttributeUsage(AttributeTargets.Method, AllowMultiple = false, Inherited = true)]
public class MultipleButtonAttribute : ActionNameSelectorAttribute
{
    public string Name { get; set; }
    public string Argument { get; set; }

    public override bool IsValidName(ControllerContext controllerContext, string actionName, MethodInfo methodInfo)
    {
        var isValidName = false;
        var keyValue = string.Format("{0}:{1}", Name, Argument);
        var value = controllerContext.Controller.ValueProvider.GetValue(keyValue);

        if (value != null)
        {
            controllerContext.Controller.ControllerContext.RouteData.Values[Name] = Argument;
            isValidName = true;
        }

        return isValidName;
    }
}

razor:

<form action="" method="post">
 <input type="submit" value="Save" name="action:Save" />
 <input type="submit" value="Cancel" name="action:Cancel" />
</form>

and controller:

[HttpPost]
[MultipleButton(Name = "action", Argument = "Save")]
public ActionResult Save(MessageModel mm) { ... }

[HttpPost]
[MultipleButton(Name = "action", Argument = "Cancel")]
public ActionResult Cancel(MessageModel mm) { ... }

Update: Razor pages looks to provide the same functionality out of the box. For new development, it may be preferable.
