    <p>I have a UserAccountController that takes routes like this <code>"/{username}/{action}"</code>.</p> <p>I'd like to create some functionality so that I can take a user to an account-specific page without knowing their username up front. I'd like to be able to use the URL <code>"/your/{action}"</code> which would catch the fact that "your" was sent as their username, get their real username (because they are logged in), and redirect them to "/their-actual-username/{action}".</p> <p>I could do this in each of the controller actions, but I'd rather have it happen some place earlier that would do this for all of the controller actions. I attempted to do this in the Controller's <code>Initialize</code> method by changing the <code>RouteData.Values["username"]</code> to the real username then attempting to <code>Response.RedirectToRoute(RouteData); Response.End()</code> but that always took me to the wrong place (some completely wrong route).</p> <hr> <p><strong>Updated:</strong> Thanks to BuildStarted for leading me to this answer:</p> <pre><code>public class UserAccountController : Controller { protected override void OnActionExecuting(ActionExecutingContext filterContext) { base.OnActionExecuting(filterContext); if ((string) filterContext.RouteData.Values["username"] != "your") return; var routeValues = new RouteValueDictionary(filterContext.RouteData.Values); routeValues["username"] = UserSession.Current.User.Username; filterContext.Result = new RedirectToRouteResult(routeValues); } } </code></pre>

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.
