    <p>I have mapped a multitude of routes to my MVC4 project as follows:</p> <pre><code>public static void RegisterRoutes(RouteCollection routes) { routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); // API routing routes.MapHttpRoute( name: "SomeApi", routeTemplate: "api/{controller}/{id}", defaults: new { id = RouteParameter.Optional } ); // Default controller mapping for non-web api views (testing) routes.MapRoute( name: "Default", url: "{controller}/{action}/{id}", defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional } ); //etc. } </code></pre> <p>This works just as planned, and my routes are properly registered. However, later on within my views, I am wanting to only display the api for certain routes, as well as allow the user to select which routes to display the api for. To do this, I need to be able to iterate through the routes that I added and use their string values to filter out the routes I want to use (example below shows how I would set a list to display only api methods using the <code>api/{controller}/{id}</code> route).</p> <pre><code>var list = group.Where(g =&gt; (g.Route.RouteTemplate == "api/{controller}/{id}")); </code></pre> <p>I am unsure exactly how to go about this. I stumbled across <a href="https://stackoverflow.com/questions/6900475/asp-net-mvc-get-urls-to-routetable-routes">this tidbit</a>, but the data within <code>RouteTable.Routes</code> can not be iterated via a <code>Route</code> type, but rather only by a <code>RouteBase</code> type (even though <code>Route</code> extends this class), which has no method that I can see to retrieve the routing string, <code>RouteTemplate</code>.</p> <p>So, it looks like my main conundrum is figuring out how to iterate through <code>RouteTable.Routes</code> and store the HttpRoutes I mapped. Any help/ideas would be greatly appreciated!</p>

    1. COCould you elaborate more on this statement? `I am wanting to only display the api for certain routes, as well as allow the user to select which routes to display the api for`. If you are looking to iterate only through Web API route collection, you could do something like `GlobalConfiguration.Configuration.Routes` to get `HttpRouteCollection`. This collection would have all your api routes.

    2. COKiranChalla: That's exactly what I was looking for! Thank you for the quick fix. For others to use as reference, this is the code that can be used to iterate (and display in Razor) the registered API Routes: `@{var routes = GlobalConfiguration.Configuration.Routes;} @foreach (var r in routes) { @r.RouteTemplate<br /> }`

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
