    text
    copied!<p>I am trying to implement a language chooser which is visible on all pages.</p> <p>My application currently has two routes:</p> <pre><code>routes.MapRoute( name: "EventDriven", url: "{language}/{eventid}/{controller}/{action}/{id}", defaults: new { language = "en", controller = "Home", action = "Index", id = UrlParameter.Optional } ); routes.MapRoute( name: "Default", url: "{language}/{controller}/{action}/{id}", defaults: new { language = "en", controller = "Home", action = "Index", id = UrlParameter.Optional } ); </code></pre> <p>And in my shared <code>_layout.cshtml</code> file I have the following action links:</p> <pre><code>@Html.ActionLink("English", ViewContext.RouteData.Values["action"].ToString(), new {language="en"}) @Html.ActionLink("Français", ViewContext.RouteData.Values["action"].ToString(), new {language="fr"}) </code></pre> <p>The problem I am encountering is I want the <code>{eventid}</code> route segment preserved, but it's not applicable on every url.</p> <p>On the home index page <code>http://localhost/MySite/</code>, the two action links are as follows:</p> <pre><code>English: http://localhost/MySite/ French: http://localhost/MySite/fr </code></pre> <p>Which is good, but on my interior page <code>http://localhost/MySite/en/2/Donation</code> the action links are:</p> <pre><code>English: http://localhost/MySite/en/2/Donation French: http://localhost/MySite/fr/Donation </code></pre> <p>If I go to <code>http://localhost/MySite/fr/2/Donation</code> then the action links are:</p> <pre><code>English: http://localhost/MySite/en/Donation French: http://localhost/MySite/fr/2/Donation </code></pre> <p>The problem is the change language action link does not contain the eventid <code>2</code> information.</p> <p>How do I make it so both links contain the event and language information (and any other route parameters unforeseeable in the future) without having to program explicitly for them?</p>
