How to return Url string from Controller a controller in mvc 4

Question

Please i am trying to generate my Url hyperlink dynamically in my MVC Application.

<a href='http://facebook.com/myPage'>Facebook</a>

The above link takes me to my facebook home page. I want to be able to change the url later on as the page name is not decided. So i tried

<a href='@Url.Action("GetFaceBookLink", "Home")'>Facebook</a>

And in my controller

 public ActionResult GetFaceBookLink()
        {
            string facebook = repository.SystemSettings.FirstOrDefault().FacebookLink;

            return this.Content(facebook);
        }

My string facebook = "http://facebook.com/mypage" . I want to be redicted to my facebook home page as usal. However, when i clicked, it returns the string url in a black pagewithout redirecting . Please how do i redirect ? how do i achieve this ? Any help would be appreciated.

@EhsanSajjad I am confused for the url string is returning . Please any tutorial, link or help with the custom helper ? — Nuru Salihu

You can create a partial view and use RenderAction to render it on main view — Ehsan Sajjad

You can do this as well: <a href='@Html.Action("GetFaceBookLink", "Home")'>Facebook</a> — Ehsan Sajjad

Brilliant. It works . But just curious why did Html.Action works and Url does'nt ? I though because we are dealing with url here so Url.Action should do the trick ? — Nuru Salihu

You need Html.Action helper here :

<a href='@Html.Action("GetFaceBookLink", "Home")'>Facebook</a>

Url.Action do not calls action, it generates url using Controller and Action name

You can redirect to another site from controller by

public ActionResult GetFaceBookLink() {
return Redirect("http://facebook.com/mypage");
}

But i coudn't use Redirect("http://facebook.com/mypage") for my case though. I got the error Child actions are not allowed to perform redirect actions," . I am doing this in my Layoutpage . A page body has been rendered already and now a controller returning a redirect , i guess thats why the error. Nonetheless , it's a great solution. Thank you :).
