Answer 1

Don't use ViewData. Use this in your Site.Master instead:

<%= ViewContext.RouteData.Values["Controller"] %>
<%= ViewContext.RouteData.Values["Action"] %>

Answer 2

Assuming that I'm reading your post correctly, and you're not trying to access the controller/action names in the view, but INSTEAD trying to do something with them, and put the result into the viewdata:

You can't do it in the constructor because the context hasn't been created yet. You need to override the Initialize method:

protected override void Initialize(System.Web.Routing.RequestContext requestContext)
    {
        base.Initialize(requestContext);

        //here the routedata is available
        ViewData["controller_name"] = (ControllerContext.RouteData.Values["Controller"];
    }

(Note that you could pass in just the ControllerContext.RouteData to your function and let it pick the values it needs.)

Answer 3

I needed to get at these alot from views, and I hit it from a slightly different angle--I wrote a few extension methods to HtmlHelper to give the current ControllerName and ActionName. A bit easier to handle as you don't need to worry about diving into the ViewData[] bag or injecting stuff at appropriate places.

Try this:

RouteData.Values.First().Value.ToString()
