Combobox充满了Enum

Question

How can I bind a specific Enum in a Combobox ?

public enum EduTypePublicEnum
  {
    [RMSEnumItem("1", "Properties.Resources.SEduAlumn")]
    Alumn,
    [RMSEnumItem("2", "Properties.Resources.SEduProfesor")]
    Profesor,
    [RMSEnumItem("3", "Properties.Resources.SEduAll")]
    All
  }

  public class EduTypePublic : RMSEnum<EduTypePublicEnum> { };

In my Form

public EduAvisosForm()
{
     InitializeComponent();

     this.myComboBox.DataSource = Edu.Consts.EduTypePublic.Enums;
     this.myComboBox.DisplayMember = "Alumn";
     this.myComboBox.ValueMember = "Alumn";
}

But, with or without the ValueMember occurs an error. When I put this code without the ValueMember occurs an error asking for the ValueMember when I put it, doesn't work.

"Is not possible define SelectedValue in a ListControl with empty ValueMember"

public abstract class RMSEnum<TEnumType>
    {
        protected RMSEnum();

        public static string CodeList { get; }
        public static string[] Codes { get; }
        public static string DescriptionList { get; }
        public static string[] Descriptions { get; }
        public static object[] Enums { get; }

        public static string Code(TEnumType value);
        public static string Description(string code);
        public static string Description(TEnumType value);
        public static TEnumType Enum(string code);
    }

Your data source items should have properties which you specified as display and value members. Eg dictionary KeyValuePairs have properties named Key and Value:

 this.myComboBox.DisplayMember = "Value";
 this.myComboBox.ValueMember = "Key";
 this.myComboBox.DataSource = 
      Enum.GetValues(typeof(EduTypePublicEnum))
          .Cast<EduTypePublicEnum>()
          .Select(e => new { 
               Key = e.ToString(), // possibly read localized string
               Value = e
           }).ToList();
