ASP.NET MVC Routing Constructs Links Based on the Current URL

Question

I have urls that look like this

~\articles\energy\topweek

~\articles\metals\latestpopular

where the second line of url is a category and the third is a filter

so the route is as follows

    routes.MapRoute("ArticleFilter",
     "articles/{category}/{filter}",
  new { controller="Article", action="Filter" })

This is pretty easy and everything works fine.

So let's say if I look at the articles {category} \ default view.

How to create links to display the current category using filters.

Example: If the current page articles\energy, I need to build article\energy\topweekand article\energy\latestpopular.

Where the category should be dynamic based on the current page. preferably on a partial image, so I can use it on different pages.
