Model is not valid in the edit time in asp.net MVC

Question

Hi,

 

i am getting error when i'm trying to edit the data in MVC 

here is my model class

 

[Table("tblUser")]

public class User

{

[Key]

public int Id { get; set; }

public string FirstName { get; set; }

[Required]

[EmailAddress(ErrorMessage = "Invalid Email Address")]

public string Email { get; set; }

[Required]

public string Password { get; set; }

[NotMapped]

[Display(Name = "Confirm password")]

[Compare("Password", ErrorMessage = "The password and confirmation password do not match.")]

public string ConfirmPassword { get; set; }

public string Salt { get; set; }

[ForeignKey("Role")]

public int RoleId { get; set; }

public Role Role { get; set; }

[ForeignKey("Department")]

public int DepartmentId { get; set; }

public Department Department { get; set; }

}

 

Confirm password, i do not want to store in the database so i given [NotMapped] 

 

i think here is the main problem ... because their is no problem in the time of user creation , but when im trying to edit those user that it is not updating , the control is not going inside of 

if (ModelState.IsValid)

{

}

 

, in the edit time from the view i remove Password , ConfirmPassword ,Salt because i dont want to edit this three field , may be because of that this model is not valid in the time of edit .

 

here is the code 

 

[HttpPost]

public ActionResult Edit(int id, User user)

{

var entity = db.User.Find(id);

user.Username = entity.Username;

user.Password = entity.Password;

user.Salt = entity.Salt;

// user.ConfirmPassword = entity.ConfirmPassword;

var errors = ModelState.Values.SelectMany(v => v.Errors);

if (ModelState.IsValid)

{

db.Entry(user).State = EntityState.Modified;

db.SaveChanges();

return RedirectToAction("Index");

}

ViewBag.DepartmentId = new SelectList(db.Department, "Id", "Name", user.DepartmentId);

ViewBag.RoleId = new SelectList(db.Roles, "Id", "Name", user.RoleId);

return RedirectToAction("Index");

}

 

i do not know exactly why error is coming always please someone help me !
