با سلام.

ViewModel زیر را در AccountViewModel  ساختم:

public class TechersViewModel
    {
        [Required(ErrorMessage ="*")]
        public string Name { get; set; }
        [Required(ErrorMessage ="*")]
        public string Family { get; set; }
        [Required(ErrorMessage ="*")]
        public string ShSh { get; set; }
        [Required(ErrorMessage ="*")]
        public string MelliCode { get; set; }
        public byte[] Pic { get; set; }
        [Required(ErrorMessage ="*")]
        public string Tell { get; set; }
        [Required(ErrorMessage ="*")]
        public string Address { get; set; }
        [Required(ErrorMessage ="*")]
        public string Email { get; set; }
        /////////////////////// Teacher///////////////////////
        public string UserID { get; set; }
        [Required(ErrorMessage ="*")]
        public string ShPersoneli { get; set; }
        [Required(ErrorMessage ="*")]
        public Nullable<byte> TahsilatID { get; set; }
        public string CV { get; set; }
        [Required(ErrorMessage ="*")]
        public Nullable<byte> sabeghtTadris { get; set; }
        public string Reshte { get; set; }
        [Required(ErrorMessage ="*")]
        public string Trend { get; set; }
        [Required(ErrorMessage ="*")]
        public string mobile { get; set; }
    }

در ویو نیز فایلهای زیر اضافه شده اند:

<script src="~/Content/js/jquery-1.11.1.min.js"></script>
<script src="~/Script/jquery.validate.unobtrusive.min.js"></script>
<script src="~/Script/jquery.validate-vsdoc.js"></script>
<script src="~/Script/jquery.validate.js"></script>
<script src="~/Script/jquery.validate.min.js"></script>
<script src="~/Script/jquery.validate.unobtrusive.js"></script>
<link href="~/Content/css/validation.css" rel="stylesheet" />

اما DataAnnonation ها کار نمی کتتد.

لطفا راهنمایی نمایید

با تشکر
