Custom Route issue with culture based url

[kamalraturi]

I am working on Culture based project. It prefix culture in url. But using LowercaseDashedRoute does not work with it. The code in route config is:

routes.Add(new LowercaseDashedRoute("{culture}/mysite/{parentitem}/{item}/{id}",
new RouteValueDictionary(
new {
culture = String.Empty,
controller = "Items",
parentitem = "Products",
action = "Details",
item = UrlParameter.Optional,
id = UrlParameter.Optional}),
new DashedRouteHandler()
)
);


And Default route is:

routes.MapRoute(
name: "Default",
url: "{culture}/{controller}/{action}/{id}",
defaults: new { culture = String.Empty, controller = "Home", action = "Index", id = UrlParameter.Optional }
);


It makes a url like:
http://localhost:62652/en-US/mysite/Solutions/Paints%2c%20Coatings%20%26%20Adhesives/9

Am I missing something?
