'Confirm password' and 'Password' do not match. MVC5

Question

I can't localize validate: 'Confirm password' and 'Password' do not match. in MVC5

[Required]
        [StringLength(100, ErrorMessage = "The {0} must be at least {2} characters long.", MinimumLength = 6)]
        [DataType(DataType.Password)]
        [Display(Name = "Password")]
        public string Password { get; set; }

        [DataType(DataType.Password)]
        [Display(Name = "Confirm password")]
        [Compare("Password", ErrorMessage = "The password and confirmation password do not match.")] //Why not display this message???????
        public string ConfirmPassword { get; set; }

Please help me localize it.

Localization means to tailor you code to a specific language. Do you mean internationalization? — Alex Dresko, Nov 15 '13 at 15:55

You have 2 options to solve this bug:

--Option 1

Change:

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

to

[System.Web.Mvc.Compare("Password", ErrorMessage = "Your custom error message")]

--Option 2 (I recommend this one)

We need to update our ASP.NET MVC 5. In your Visual Studio go to the Package Manager Console and type:

PM> update-package

You migh get an error in the:

public ApplicationDbContext()
            : base("DefaultConnection")
        {
        }

That error is caused by the update in the internal structure of MVC 5. To solve that error do this: https://stackoverflow.com/a/23090099/2958543

It appears that it is a known issue and is not working correctly at the moment - http://aspnetwebstack.codeplex.com/workitem/1401.

However a temporary workaround would be using the Compare attribute from System.Web.Mvc, which is marked obsolete. Here is an example:

using CompareObsolete = System.Web.Mvc.CompareAttribute;

...

[StringLength(100, ErrorMessage = "The {0} must be at least {2} characters long.", MinimumLength = 6)]
[DataType(DataType.Password)]
[Display(Name = "Password")]
public string Password { get; set; }

[DataType(DataType.Password)]
[Display(Name = "Confirm password")]
[CompareObsolete("Password", ErrorMessage = "The password and confirmation password do not match.")]
public string ConfirmPassword { get; set; }

I am currently using this workaround until the official fix is available. Everything is working perfectly fine - I am using this attribute to localize error messages using Resources.

Just don't forget to update it once the official fix comes out.

EDIT: The issue has been fixed in the latest release.

There seems to be two types of CompareAttribute. Looking at MSDN, the one with namespace System.Web.Mvc seems to be obsolete and they suggest using the one with namespace System.ComponentModel.DataAnnotations. Link: https://msdn.microsoft.com/en-us/library/system.web.mvc.compareattribute(v=vs.118).aspx

With Visual Studios, you'll have to be explicit with the annotation and add the namespace to attribute in the annotation like the following:

[System.ComponentModel.DataAnnotations.CompareAttribute("Password", ErrorMessage = "The password and confirmation password do not match.")]
