how do i show popup/alert and then RedirectToAction()

I wish to display a Javascript type popup to alert the user that he has to fill in some additional data in a previous View before continue processing this View, and then actually redirect the user to that View.

At the moment my code is as follows :-

        if (viewModel.compData.GG != "")
            CalcGradingPoints();
        else
        {
            Response.Write(@"<script language='javascript'>alert('You have to Select a Grading before doing this calculation');</script>");
            return RedirectToAction("Index", "Grading");
        }

        return View(viewModel);

It is redirecting correctly, however I cannot see the error message, so for the user, it is like he is stuck on the first View and not moving.

How can I display an error message, allow the user to confirm that he saw the message by clicking the message, and then redirecting?

Thanks for your help and time

You should use the confirm() function : http://www.javascripter.net/faq/confirm.htm

usage :

if (confirm("Your question")) { 
 window.location = "http://www.google.com/" //redirect HERE
}

Actually I thought there was an easy way to do it. I have taken a different approach and set everything on the first View to a default value, so that the second View will never be blank.

Thanks for your help

RedirectToAction is 302 HTTP redirect, you will never see anything with Response.Write. I also had same scenario and create for with logic separate view, where I show message and then redirect user. My model contain: title, message, controller, action and etc. Then you just fill view and create link with @Url.Action.

meta example:

<meta http-equiv="REFRESH" content="0;url=http://www.your-link.com">

The content="0; may be changed to the number of seconds you want the browser to wait before redirecting.
