c# - MVC Model Validation Multiple View -

-

i have model class 6 fields(all required field validation). have 2 views using model. have 3 fields in 1 view(lets abc.cshtml) , 6 in another(lets xyz.cshtml) problem is,when submitting form in abc.cshtml , checking modelstate.isvalid property in controller,it validating fields not presented on view,so property appears false. model

  public class usermodel   {         [required(errormessage = "enter username")]         public string username { get; set; }          [required(errormessage = "enter password")]         public string password { get; set; }          [required(errormessage = "enter firstname")]         public string firstname { get; set; }          [required(errormessage = "enter lastname")]         public string lastname { get; set; }          [required(errormessage = "enter contact")]         public string contact { get; set; }          [required(errormessage = "enter address")]         public string address { get; set; }   }

public class basemodel{        [required(errormessage = "enter firstname")]         public string firstname { get; set; }          [required(errormessage = "enter lastname")]         public string lastname { get; set; }          [required(errormessage = "enter username")]         public string username { get; set; }   }     public class usermodel : basemodel   {          [required(errormessage = "enter password")]         public string password { get; set; }          [required(errormessage = "enter contact")]         public string contact { get; set; }          [required(errormessage = "enter address")]         public string address { get; set; }   }  hope reduce redundancy , work different view , think best way tackle kind of problem
