Question

I have some action for example

public ActionResult SomeAction(Model login)
{
  .....
  //Login fail
  ModelState.AddModelError("loginError","Login fail");

  if(!ModelState.IsValid)
  {
    //here i need send model
    return RedirectToAction("SomeAction2","Controller");
  }

  return View(login);
}

SomeAction2 is not as same type Model as SomeAction. But SomeAction2 has a partial view that have same type with view SameAction. Can anyone tell me how I can send a model error to this partial view?

Answer 1

Just have to use
return View("ViewName");

Then you can use a ViewBag collection to add the error messages.
