Question

Lets say I have _Layout.cshtml where I have this:

 @if (ViewBag.SignUpURL == null)
        {   
            <a href="@Url.Content("~/Home/Join")" ><span>
                <strong>JOIN NOW!</strong></span></a>
        }
        else
        {         
            <a href="@ViewBag.SignUpURL" ><span>
                <strong>JOIN NOW!</strong></span></a>
        }

When I try to populate ViewBag.SignUpURL under

 public ActionResult Index()
        {
            ViewBag.SignUpURL = HttpContext.Request.Url.AbsoluteUri.Replace("Index", "SignUp");

            return View();
        }

Index view uses _Layout.cshtml.

And nothing happens…

In general I need somehow pass data to Layout page from page that uses it.

Is it possible to do?

THANK YOU!!!

You should consider using Html.RenderAction() which will then go back to controller action that you specify, and you’ll be able to return a partial view with a model for it:

View:

@Html.RenderAction("GetSignUp")

Controller action

public ActionResult GetSignUp()
{
//do your logic here

    return PartialView("_SignUp");
}
