Hi,
 
I have an Employee Class in which you have to capture the employee's physical and postal address.
Both the physical and postal address require a Province.
I have created a Province Class to store the Provinces.
 
I need to have a dropdown list of the Provinces for both the physical and postal address of a single employee but when I add the second dropdown list, it doesn't work.
 
My Employee Class is as follows;
  1. using System;  
  2. using System.Collections.Generic;  
  3. using System.ComponentModel.DataAnnotations;  
  4. using System.ComponentModel.DataAnnotations.Schema;  
  5. using System.Linq;  
  6. using System.Web;  
  7.   
  8. namespace LMKSystem.Models  
  9. {  
  10.     public class Employee  
  11.     {  
  12.         [Key]  
  13.         public int EmployeeId { get; set; }  
  14.   
  15.         [Display(Name = "Employee Number")]  
  16.         [MaxLength(50)]  
  17.         public string EmployeeNumber { get; set; }  
  18.   
  19.         //Foreign Key from Title Class  
  20.         [Display(Name = "Title")]  
  21.         public int TitleId { get; set; }  
  22.   
  23.         [ForeignKey("TitleId")]  
  24.         public virtual Title Titles { get; set; }  
  25.         //end  
  26.   
  27.         [MaxLength(50)]  
  28.         //[Required(ErrorMessage ="An employee name is needed to continue")]  
  29.         public string Name { get; set; }  
  30.   
  31.         [Display(Name = "Second Name")]  
  32.         [MaxLength(50)]  
  33.   
  34.         public string SecondName { get; set; }  
  35.   
  36.         [MaxLength(50)]  
  37.         public string Surname { get; set; }  
  38.   
  39.         [Display(Name = "A.K.A")]

  51.   
  52.         //Foreign Key from Gender Class  
  53.         [Display(Name = "Gender")]

  160. } 
 
My Province Class is;
  1. using System;  
  2. using System.Collections.Generic;  
  3. using System.ComponentModel.DataAnnotations;  
  4. using System.Linq;  
  5. using System.Web;  
  6.   
  7. namespace LMKSystem.Models  
  8. {  
  9.     public class Province  
  10.     {  
  11.         [Key]  
  12.         public int ProvinceId { get; set; }  
  13.   
  14.         [Display(Name = "Province")]  
  15.         public string SAProvince { get; set; }  
  16.     }  
  17. }  
My DbSet is as follows;
  1. public class ApplicationDbContext : IdentityDbContext<ApplicationUser>  
  2. {  
  3. public DbSet<Employee> Employees { get; set; }  
  4. public DbSet<Title> Titles { get; set; }  
  5. public DbSet<Gender> Genders { get; set; }  
  6. public DbSet<Group> Groups { get; set; }  
  7. public DbSet<WorkPermit> WorkPermits { get; set; }  
  8. public DbSet<Passport> Passports { get; set; }  
  9. public DbSet<Language> Languages { get; set; }  
  10. public DbSet<Marital> Maritals { get; set; }  
  11. public DbSet<Province> Provinces { get; set; }  
  12. }  
How can I have one dropdown list for the postal address Province and one dropdown list for the physical address Province in the same class?
I am fairly new to dropdown lists.
Thanking you in advance.
Regards,
Kyle
