Answer 1

Hi Rajesh,

Compare validator will accept ControlToValidate property that should be set to your confirm password control,ControlToCompare property that should be set to your password control. DataType property is also there to set the comparison datatype, and you can set it to true.

Answer 2

This sample is taken straight from the mvc2 template and the MvcMusicStore sample (on codeplex).

This sample assumes you are using strongly typed views.

[PropertiesMustMatch("NewPassword", "ConfirmPassword", ErrorMessage = "The new password and confirmation password do not match.")]
public class ChangePasswordModel
{
    [Required]
    [DataType(DataType.Password)]
    [DisplayName("Current password")]
    public string OldPassword { get; set; }

    [Required]
    [ValidatePasswordLength]
    [DataType(DataType.Password)]
    [DisplayName("New password")]
    public string NewPassword { get; set; }

    [Required]
    [DataType(DataType.Password)]
    [DisplayName("Confirm new password")]
    public string ConfirmPassword { get; set; }
}
