Action in controller received empty model from Html.BeginForm - ASP.NET MVC - asp.net-mvc

Question

I have stucked for 3 days. There is nowhere I had been looking for this problem. When I submit the form, Controller action method doesnt get the model.
My base view Login.cshtml
#{
string durum = ViewBag.Style;
switch (durum)
{
case "Login":
Html.RenderAction("_Login", "Dashboard");
break;
case "LostPassword":
Html.RenderAction("_LostPassword", "Dashboard");
break;
case "RegisterForm":
Html.RenderAction("_RegisterForm", "Dashboard");
break;
default:
Html.RenderAction("_Login", "Dashboard");
break;
}
}
One of my partial view _LostPassword.cshtml
#model HaberSitesi._Entities.Kullanici
#using (Html.BeginForm("LostPassword", "Dashboard", FormMethod.Post, new { #class = "forget-form", #style = "display:block" }))
{
if (TempData["ForgotPassword"] != null)
{
<div class="alert alert-warning ">
<button class="close" data-close="alert"></button>
<span>#TempData["ForgotPassword"]</span>
</div>
}
<h3>Şifrenizi mi unuttunuz ?</h3>
<p> Şifrenizi almak için lütfen E-Posta adresinizi giriniz. </p>
<div class="form-group">
<div class="input-icon">
<i class="fa fa-envelope"></i>
#Html.TextBoxFor(x => x.EPosta, new { #class = "form-control placeholder-no-fix", #type = "email", #autocomplete = "off", #placeholder = "Eposta", Name = "email" })
#Html.ValidationMessageFor(x => x.EPosta)
</div>
</div>
<div class="form-actions">
#Html.ActionLink("Geri Dön", "Login", "Dashboard", new { }, new { #type = "button", #id = "back-btn", #class = "btn grey-salsa btn-outline" })
<button type="submit" class="btn green pull-right"> Gönder </button>
</div>
}
And the action in controller DashboardController.cs
public ActionResult LostPassword()
{
VeriTransfer();
return View("Login");
}
[HttpPost]
public ActionResult LostPassword(Kullanici kullanici)
{
string kullaniciEposta = kullanici.EPosta;
Kullanici user = _kullaniciBll.Get(kullaniciEposta);
if (user != null)
{
TempData["ForgotPassword"] = "Şifreniz e-posta adresinize gönderildi.";
}
else
{
TempData["ForgotPassword"] = "Kayıtlarımızda e-posta adresiniz bulunamadı";
}
VeriTransfer();
return View("Login");
}
When I click submit button, I cant get any data (Kullanici kullanici) in controller. Every property comes null or default data value from model.
Note: Maybe my codes could have some other mistakes which are irrelevant with my problem. I just wonder why I get empty model. Thanks at least you have read my problem.

Answer 1

Your property is called EPosta but you changed the name of it to Name="email".So when the POST action happens it sends a property called email to the controller action and your Kullanici object expects a property called EPosta
Both of these will fix your problem:
Change Name="email" to Name="EPosta" or
Remove Name="email" completely
But like Stephen said it's better to remove it completely,because if you rename your property to EPosta2 in future and forget to change the name to Name="EPosta2" your POST will no longer work
