How to Configure Areas in ASP.NET MVC3

Question

Is anyone knows how to Configure Areas in ASP.NET MVC3. I read an article about Areas in here. But that article is not based on MVC3. In MVC3 there is no function named MapRootArea in RouteCollection routes which is found in Global.asax

routes.MapRootArea("{controller}/{action}/{id}", 
                 "AreasDemo", 
                  new { controller = "Home", action = "Index", id = "" });

When i create a New Area using MVC3, i got a class of that area which inherited from AreaRegistration and look like following: (here Blogs is the area name)

public class BlogsAreaRegistration : AreaRegistration
{
    public override string AreaName
    {
        get
        {
            return "Blogs";
        }
    }

    public override void RegisterArea(AreaRegistrationContext context)
    {
        context.MapRoute(
            "Blogs_default",
            "Blogs/{controller}/{action}/{id}",
            new { action = "Index", id = UrlParameter.Optional }
        );
    }
}

Would anyone please help me how do i configure area in MVC3. Any kind of link would be helpful also.

Answer 1

Right click on your web project and select Add -> Area... Then type the name of the area and Visual Studio will take care of the rest which is to generate all the necessary classes. For example the area registration might look like this:

public class AreasDemoAreaRegistration : AreaRegistration
{
    public override string AreaName
    {
        get
        {
            return "AreasDemo";
        }
    }

    public override void RegisterArea(AreaRegistrationContext context)
    {
        context.MapRoute(
            "AreasDemo_default",
            "AreasDemo/{controller}/{action}/{id}",
            new { action = "Index", id = UrlParameter.Optional }
        );
    }
}

and in Application_Start of your Global.asax all you need is:

AreaRegistration.RegisterAllAreas();

You can have the same controller name in the root and the area, you just have to define it.

In your global.asax, add the last line of the routes.maproute as shown below

 routes.MapRoute(
      "Default", // Route name
       "{controller}/{action}/{id}", // URL with parameters
       new { controller = "Home", action = "Index", id = UrlParameter.Optional },// Parameter defaults
       new[]{"YourNameSpace.Controllers"}
  );

also, add the name of the controller in your ares/?????AreaRegistration.cs file

 context.MapRoute(
        "Membership_default",
        "Membership/{controller}/{action}/{id}",
         new { controller= "Home", action = "Index", id = UrlParameter.Optional }
      );
