How to pass parameter while redirecting to Action on Ajax Success?

Question

I have two View (Create and Completed) and a Controller. I use Ajax for creating new records (Create) in a popup window and after the operation succeeded, I want to close the Create and display the returned message from the Controller. Although I can easily show the message on Create view, I cannot pass this message to Completed view (I want to close or hide Create and open Completed to show the message. So, could you clarify me please how to succeed this? On the other hand, is it not possible to determine if the request is an Ajax request with Request.IsAjaxRequest() method as shown below. Any idea?

Controller:

[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Create([Bind(Exclude = null)] MyModel model)
{  
    if (ModelState.IsValid)
    {
        //... (removed for brevity)
        TempData["message"] = "Operation succeeded.";
        var redirectUrl = new UrlHelper(Request.RequestContext).Action("Completed", "Home", new { /* params */ });
        return Json(new { success = true, message = TempData["message"], url = redirectUrl });
    }
}

View:

$('form').submit(function (event) {
    event.preventDefault();
    $.ajax({
        type: "POST",
        url: '@Url.Action("Create", "Home")',
        data: formdata,
        dataType: "json",
        processData: false, 
        contentType: false, 
        success: function (response) {
           if (response.success) {
               //I can pass id in the url, but I need to pass response.message as parameter
               window.location.href = 'Url.Action("Completed", "Home", new { id=1 })';
            }
        }
    });
});

On the other hand, the Request.IsAjaxRequest() in the Controller always returns true even if I make the request from another View (Create on a new page View) that is use Html.BeginForm instead of Ajax post. Is there a problem with Request.IsAjaxRequest() in MVC5?

if (Request.IsAjaxRequest())
{
    //Always returns true
}

Any help would be appreciated.

In Success block of ajax before window.location.href = 'Url.Action("Completed", "Home", new { id=1 })'; Use alert(response);

Remove unnecessary if block on success block
