How to display alert message after inserting data into database?

Question

I have create web app in MVS 3 but failed to display alert message after data insert into database

Controller code:

[HttpPost]
        public ActionResult QuestionBank(QuestionBank questionbank)
        {
            if (ModelState.IsValid)
            {
                dbEntities.QuestionBanks.AddObject(questionbank);
                dbEntities.SaveChanges();
                //questionbank.SendEnquiryEmail(questionbank);
                ViewData["Message"] = "Data inserted";
                return RedirectToAction("QuestionBank");

            }
            return View(questionbank);
        }

Used ViewData["Message"] = "Data inserted"; which is not displayed message :( whats going wrong or i placed it somewhere else? OR ELSE I MAY HAVE THIS CODE

<script type="text/javascript">
    //i'm using jquery ready event which will call the javascript chunk after the page has completed loading
    $(document).ready(function () {
        //assuming that your variable name from the code behind is bInsertSuccess
        var bSuccess = "<%= myvar %>";
        if (bSuccess) {
            alert("Successfully Inserted");
        }
    });
</script>

but i dont know where i declare that variable myvar which checks insertion plz help

Answer 1

On your .chsthml page:

<script type="text/javascript">
    $(document).ready(function () {
        var msg = '@ViewBag.Message';

        alert(msg);
    });
</script>

in your action:

ViewBag.Message = "1";

Edit: Apply conditional check in script:

<script type="text/javascript">
    $(document).ready(function () {

        var msg = '@ViewData["Message"]';
        if(msg=='1')
        alert("you are done with your thing");
    });
</script>

In view:

ViewData["Message"] = "1";

ViewData["Message"] would result in same thing here.

Try to user

TempData

instead of

ViewData
