In this article I am going to explain how to change password in
MVC application.
Description:
I want to add change password functionality for logged in users. To
change password users have to enter current password, after that new password
and confirm the new password.
Implementations:
Please check the previous post Create login form and maintain authenticated
user’s detail in MVC application.
Model
public partial class Login
{
public int Id { get; set; }
[Required(ErrorMessage = "Please enter username")]
[DisplayFormat(ConvertEmptyStringToNull
= true)]
[Display(Name = "Username")]
public string Username { get; set; }
[Required(ErrorMessage = "Please enter password")]
[DataType(DataType.Password)]
public string Password { get; set; }
[Display(Name = "Confirm password")]
[Required(ErrorMessage = "Please enter confirm password")]
[DataType(DataType.Password)]
public string Confirmpwd { get; set; }
public Nullable<bool> Is_Deleted { get; set; }
}
