Answer
ViewData/ViewBag: For same request only.
TempData: Persisted across redirects using cookies or session. Ideal for one-time messages.
Quick Answer
TempData survives exactly one redirect. Set it before RedirectToAction(); read it in the destination action or view. ViewData is a dictionary — controller sets it, view reads it within one request. ViewBag is dynamic syntax over ViewData (ViewBag.Title = "X" is ViewData["Title"] = "X"). TempData uses cookie or session; the others don't persist.
