public int Id { get; set; }

[Required(ErrorMessage = "please provide First Name", AllowEmptyStrings = false)]

[AllowHtml]

public string Name { get; set; }

public string Address { get; set; }

[DataType(DataType.EmailAddress)]

[Required(ErrorMessage = "Please enter correct email address")]

hi Ajay,
No the one you implemented was wrong.
You should pass in the Model you created, otherwise all the attribute you set in the Model will not be validated at all. (i.e. the ModelState.IsValid is not used at all)
the parameter in your controller method should be the Model.
i.e.
publicActionResultContactUs(ContactUsModelmodel)
//ContactUsModel==>i.e.thecontactuclassyoumentioned.

I allready create controller but it is not working Lida weng ...
see the controller :-
[HttpGet]
public ActionResult contactus()
{
return View();
}
[HttpPost]
public ActionResult contactus(contactu obj,string Name, string Email,string Phone,string Address, string Subject,string Message)
{
if (ModelState.IsValid)
{
obj.Name = Name;
obj.Email = Email;
obj.PhoneNo = Phone;
obj.Address = Address;
obj.Subject = Subject;
obj.Msg = Message;
db.contactus.Add(obj);
db.SaveChanges();
return RedirectToAction("contactus", "AdminUserLogin");

}
else
{
return View(obj);
}
}

hi, it needs to be done on the server level because asp.net MVC models are server side implementations:
publicclassYourController:Controller
{
publicActionResultContactUs(ContactUsModelmodel)
{
if(this.ModelState.IsValid)
{
//dosomething
}
else
{
//dosomethingforerrorhandling
}
}
}
And in your cshtml view, you can add additional code for showing the ErrorMessage details.
