    <p>I am trying to make a simple multi-language website. Overriding FindView to get the file based on the language is easy, my problem comes in the routing part.</p> <p>I would like to do is: (have a website with 2 languages - pt-br and en-us, let abbreviate to onlu pt and en - the default would be PT)</p> <p>User types www.mysite.com -> would find the languages in the user header request and if the user doesn´t have any of them, he would be redirected to the default PT, so the end result would be www.mysite.com in Portuguese. If he has en, he would be redirected to www.mysite.com/en/ , the result would be the view in English.</p> <p>If the user types www.mysite.com/pt/ -> I would check that he wants the default and would redirect to www.mysite.com in Portuguese.</p> <p>I did a custom engine to get the correct view based on the language. But it´s not working 100% because the routing problem.</p> <p>IN my case I am trying to route with </p> <pre><code>routes.MapRoute( "Localization", // Route name "{lang}/{controller}/{action}", // URL with parameters new { lang = "pt", controller = "Home", action = "Index" } //defaults ); </code></pre> <p>But with this, when someone types /pt/ will not redirect to the root of the site.</p> <p>Another problem with the route is that I don´t want to anyone typing the controller name, I just want the action, my website just have one Home controller with few actions.</p> <p>Another problem is the that I want a different action name, like, CONTACT in English and CONTATO in Portuguese, they should appear on the address bar like www.mysite.com/Contato or www.mysite.com/en/Contact</p> <p>Mu Engine I did base on this solution <a href="http://www.counity.at/blog/2012/asp-net-mvc3-localization-using-culture-dependent-views/" rel="nofollow">http://www.counity.at/blog/2012/asp-net-mvc3-localization-using-culture-dependent-views/</a> by <a href="http://www.counity.at/blog/author/breigo/" rel="nofollow">Guido Breitenhuber</a></p> <p>Here is the code with some tweaks (it´s not working 100% yet)</p> <pre><code>using System;

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
