Question

Hi people I have the following code (shown below) and I am trying to change it (its my code) so i can display a message box or some alert saying the book has been saved using an if statement in C# ASP.net MVC3

[HttpPost]
    [ValidateInput(false)]
    public ActionResult Create(BooksItem booksitem)
    {
        try
        {
            using (var db = new Booksforsale())
            {
                db.BooksItem.Add(booksitem);
                db.SaveChanges();
            }

            return RedirectToAction("Index");
            }
        catch
        {
            return View();
        }
    }

Is there a way to change this to an If statement so when its saved a message box or an alert appears saying it has been saved. I would like real simple coding nothing to complex that will be hard for me to implement.

Thank You

I have tried the following:

    [HttpPost]
    [ValidateInput(false)]
    If public ActionResult Create(BooksItem booksitem)
    {
        try
        {
            if using (var db = new Booksforsale())
            {
                db.BooksItem.Add(booksitem);
                db.SaveChanges();
            }
            else viewbag.message="been added"
            {
            return RedirectToAction("Index");
            }

        catch
        {
            return View();

        }
    }

This has not worked thank you so much people for any help received really appreciate it thanks

You could store the message inside TempData so that it is available on the next request after you redirect:

[HttpPost]
[ValidateInput(false)]
public ActionResult Create(BooksItem booksitem)
{
    try
    {
        using (var db = new Booksforsale())
        {
            db.BooksItem.Add(booksitem);
            db.SaveChanges();
        }
        TempData["message"] = "The item has been saved";
        return RedirectToAction("Index");
    }
    catch
    {
        return View();
    }
}

and inside the Index action that you are redirecting to fetch the message from TempData and pass it to the view:

public ActionResult Index()
{
    ViewBag.Message = TempData["message"];
    return View();
}

and obviously display this message somewhere in the corresponding view:

<div>@ViewBag.Message</div>
