[Solved] ModelState.IsValid is always returning false in ASP.Net MVC

I have a quick question I am updating my user and there role and my modelstate.isvalid is failing.

So the user does not get updated in the database. I don’t have anything [required] that isn't being entered in a textbox even when I try to enter all fields it still fails. Not sure why.

    public class UpdateUserViewModel
    {
        public string UserId { get; set; }
        [Display(Name = "User ID")]
        public string IdShortened { get; set; }
        [Required]
        [EmailAddress]
        [Display(Name = "Email")]
        public string Email { get; set; }
        [Required]
        [Display(Name = "Username")]
        public string UserName { get; set; }
        [Display(Name = "Your Name")]
        public string Name { get; set; }
        [Display(Name = "Phone Number")]
        public string PhoneNumber { get; set; }
        [DataType(DataType.DateTime), DisplayFormat(DataFormatString = "{0:dd/MM/yyyy}", ApplyFormatInEditMode = true)]
        [Display(Name = "Birthday")]
        public DateTime Birthday { get; set; }
        [Display(Name = "Date Created")]
        public DateTime? DateCreated { get; set; }
        [Required]
        [Display(Name = "User Roles")]
        public string UserRoles { get; set; }
    }

        [HttpPost]
        [ValidateAntiForgeryToken]
        public ActionResult EditSuperAdmin([Bind]UpdateUserViewModel model)
        {
            var store = new UserStore<ApplicationUser>(context);
            var manager = new UserManager<ApplicationUser>(store);

            if (ModelState.IsValid)
            {
                var user = manager.FindById(model.UserId);                                
                TempData["Success"] = "User Updated Successfully";              
                return RedirectToAction("GetAllUsers", "SuperAdmin");
            }
            TempData["Error"] = "User Update Failed";
            return RedirectToAction("Dashboard");
        }
