Display a label instead of returning a view

This is the relevant code of my View:

        @Html.LabelFor(model => model.nickName)
        @Html.TextBoxFor(model => model.nickName, new { @class = "RegisterControls" })
        <br /><br />

        @Html.LabelFor(model => model.email)
        @Html.TextBoxFor(model => model.email, new { @class = "RegisterControls" })
        <br /><br />            

        @Html.LabelFor(model => model.password)
        @Html.TextBoxFor(model => model.password, new { @class = "RegisterControls" })

And Action method:

public ActionResult RegisterNewUser(string uName, string email, string password)
    {
        ViewBag.Message = "Register";

        if (!users.RegisterUser(uName, email, password))
        {
            ViewBag.DeniedMsg = "A user with that email already exists";
            return; //This doesn't work, as I should return a View
        }            
        return PartialView("_Register");            
    }

If a user types in an already existing email upon registering (and when clicking the link that says "Create account", I want to just add a label saying that the email already exists, and NOT returning an entire view. See my action method for (hopefully) clearity.

The create account link:

@Ajax.ActionLink("Create account", "CheckifUserEmailExists", "RegisteredUsers", new AjaxOptions { UpdateTargetId = "updaterDiv" }, new { @class = "actionButtons" })

Actually, more generally. If someone types in something in a text box, you will call the action method in the proper Controller. But this Action method always returns a view. But what if you just want to display a message to that user (e.i. saying "account created") and staying on the same view. How do you handle this? I can't do this, since I have to return a view, but I want to stay on the same view, and display the message there

Change your RegisterNewUser action like this:

public ActionResult RegisterNewUser(string uName, string email, string password)
    {
        ViewBag.Message = "Register";
        String msg = "";
        if (!users.RegisterUser(uName, email, password))
        {
            msg = "A user with that email already exists";
        }
        ViewBag.DeniedMsg = msg;
        return PartialView("_Register");            
    }

And print the ViewBag string message at the top of partial view. Like:

@VeiwBag.DeniedMsg

If user doesn't exist, nothing will get printed.

Create one more action to return string. Like:

public string UserExistsMsg(string msg)
{
    return msg;
}

And change your RegisterNewUser action like this:

public ActionResult RegisterNewUser(string uName, string email, string password)
    {
        ViewBag.Message = "Register";

        if (!users.RegisterUser(uName, email, password))
        {
            return RedirectToAction("UserExistsMsg", "A user with that email already exists");
        }
        return PartialView("_Register");            
    }
