Question

@Html.ActionLink("pSearch", "Results", null, new {target="_blank"})

doesn’t work because it doesn’t post the form data to the “Results” controller action and all that is returned is a 404 error.

Answer 1

Assuming you are using the default routes:

routes.MapRoute(
    "Default",
    "{controller}/{action}/{id}",
    new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);

then:

@Html.ActionLink("pSearch", "Results", null, new { target="_blank" })

will generate:

<a href="/Home/Results" target="_blank">pSearch</a>

So if you expect to get anything else than 404 hopefully you have defined a Results action inside HomeController, have you?

Like this:

public class HomeController : Controller
{
    public ActionResult Results()
    {
        return View();
    }
}

Otherwise you can’t really expect much more than a 404 error, can you?

it’s obvious, but probably worth mentioning, that this action will expect ~/Views/Home/Results.cshtml or ~/Views/Home/Results.aspx view to be defined. You have defined it in this location, haven’t you?
