Answer 1

I recently created an HTML Helper for this that looks like:

public static string NavigationLink(this HtmlHelper helper, string path, string text)
{
    string cssClass = String.Empty;
    if (HttpContext.Current.Request.Path.IndexOf(path) != -1)
    {
        cssClass = "class = 'selected'";
    }

    return String.Format(@"
{2}
", path, cssClass, text);
}

The Implementation looks like this:

  

  <%=Html.NavigationLink("/Path1", "Text1")%>
  <%=Html.NavigationLink("/Path2", "Text2")%>
  <%=Html.NavigationLink("/Path3", "Text3")%>
  <%=Html.NavigationLink("/Path4", "Text4")%>
