Answer 1

First Make a Helper Class and HTML Helper method

 public static string IsActive(this HtmlHelper html,string control,string action)
    {
        var routeData = html.ViewContext.RouteData;

        var routeAction = (string)routeData.Values["action"];
        var routeControl = (string)routeData.Values["controller"];

        // both must match
        var returnActive = control == routeControl &&
                           action == routeAction;

        return returnActive ? "active" : "";
    }

And in View or Layour Section Just Call the Helper Method with appropriate Conntroller and Action.

  @using YourNamespace.HtmlHelpermethodName

 

this will add "active" string in class attribute and it will show like
