Here's a really simple way to do it:
if (ModelState.IsValid)
{
return RedirectToAction("HomeScreen", "HomeScreen");
}
StringBuilder sb = new StringBuilder();
sb.Append("You have a bunch of errors:");
foreach (ModelState modelState in ModelState.Values) {
foreach (ModelError error in modelState.Errors) {
sb.Append(error + "\n");
}
}
ViewData["Error"] = sb.ToString();
return View("LoginScreen");
And in your view:
@if(!String.IsNullOrEmpty(ViewBag["Errors"])){
@:<script type="text/javascript">alert('@ViewBag["Errors"]')</script>
}
This is untested, but should give you the idea.
