I want to implement ModelState.AddModelError on RedirectToAction in MVC. Currently, I am not getting error message. Can anyone please help me?
if(ModelState.IsValid)
{
var HList = hDetails.HTrackerList().Where(x => x.AccId == user.AccountID && x.UserId == user.Id).Select(y=>y.HorseId).ToList();
var datainList = HList.Contains(model.HorseId);
if(!datainList)
{
hDetails.InsertHorse(model);
}
else
{
ModelState.AddModelError("datainList", "Horse is already exist. Do you want to update it?");
}
}
return RedirectToAction("Home");
In the View:
#Html.ValidationMessage("datainList")
In your ontroller class:
public class YourController : Controller
{
[HttpPost]
public ActionResult TestMethod()
{
if(ModelState.IsValid)
{
var HList = hDetails.HTrackerList().Where(x => x.AccId == user.AccountID && x.UserId == user.Id).Select(y=>y.HorseId).ToList();
var datainList = HList.Contains(model.HorseId);
if(!datainList)
{
hDetails.InsertHorse(model);
}
else
{
TempData["datainListError"] = "Horse is already exist. Do you want to update it?";
}
}
return RedirectToAction("Home");
}
}
Then in the Home Controller:
public class HomeController : Controller
{
public ActionResult Index()
{
if(TempData.ContainsKey("datainListError"))
{
ViewBag.ErrorMessage = TempData["datainListError"].ToString();
}
return View();
}
}
Then in the Index View:
#if(ViewBag.ErrorMessage != null)
{
<div class="alert alert-danger">#ViewBag.ErrorMessage</div>
}

Try to use a DropDownListFor instead of a DropdownList. The error you mention means that you are having NULL in the SelectListItem. You should create a list of ListItem in the DropDownList.
(I'm not sure if I'm correct or not. I'm just trying to help quickly.)
my code:
public class StateManagementController : Controller
{
public void OwnerTest()
{
if (Session["Owner"] == null)
{
Logowanie();
}
}
public ActionResult Logowanie()
{
return RedirectToAction("Log", "Owner");
}
}
public class AnimalController : StateManagementController
{
public ActionResult MyAnimals()
{
OwnerTest();
//some code here
return View(animals.ToList());
}
}
The problem is that even if the session is null and Redirect is reached it doesn't redirect me but it still goes to ,,some code" in MyAnimals action, how can I stop it in ActionResult Logowanie? i dont want to change code in MyAnimals, I want only to use function there without checking if it returns something.
You Logowanie Action may return an ActionResult but the OwnerTest method ignores the returned result. Try this:
public class StateManagementController : Controller
{
public ActionResult OwnerTest()
{
if (Session["Owner"] == null)
{
return Logowanie();
}
else
{
return null;
}
}
public ActionResult Logowanie()
{
return RedirectToAction("Log", "Owner");
}
public class AnimalController : StateManagementController
{
public ActionResult MyAnimals()
{
var temp = OwnerTest();
if (temp != null)
{
return temp;
}
else
{
//some code here
return View(animals.ToList());
}
}
}
I am having an issue with checking the authentication when a user logs in to my site. So I have a login page (Login.cshtml), that of course a user would login from. From there the user would be sent to an index page. My issue is that when i hit this
#if (Request.IsAuthenticated)
{
<strong>#Html.Encode(User.Identity.Name)</strong>
}
else
{
<strong>Something went wrong</strong>
}
it fails into the else statement and writes something went wrong. Any advice on how to combat this error would be greatly appreciated. Thank you in advance.
Index.cshtml:
#{
ViewBag.Title = "Index";
Layout = "~/Views/Shared/_Layout.cshtml";
}
<h2>Index</h2>
#if (Request.IsAuthenticated)
{
<strong>#Html.Encode(User.Identity.Name)</strong>
}
else
{
<strong>Something went wrong</strong>
}
My UserContoller(has all the methods for the login):
public ActionResult Index()
{
var user = db.User.Include(u => u.UserName);
var loggedInUser = User.Identity.Name;
return View();
}
[HttpGet]
public ActionResult Login()
{
return View();
}
[HttpPost]
public ActionResult Login(Models.User user)
{
if (ModelState.IsValid)
{
if (isValid(user.UserName, user.Password))
{
FormsAuthentication.SetAuthCookie(user.UserName, false);
return RedirectToAction("Index", "User");
}
else
{
ModelState.AddModelError("", "User Name or Password is incorrect");
}
}
return View(user);
}
private bool isValid(string UserName, string Password)
{
bool isValid = false;
//var user = db.User.SingleOrDefault(u => u.UserName == UserName);
var user = db.User.Where(u => u.UserName == UserName).FirstOrDefault();
var pass = db.User.Where(u => u.Password == Password).FirstOrDefault();
if (user != null && pass != null)
{
isValid = true;
}
return isValid;
}
