Modify display name of Enum types

I have

 public enum SomeEnum
 {
   Enum1,
   Enum2,
  ............
 }

my class has property

public SomeEnum Value {......}

When I edit that property I would like combo box display not Enum1, Enum2 but different names so i created TypeConverter

 public class SomeEnumConverter: TypeConverter
 {
  public override bool CanConvertTo(....) ....

  public override object ConvertTo(......)
  {
   return {  my logic to display different SomeEnum string representation };
  }

 Applied type converter to my property doesnt work (I am using latest night build)

 [TypeConverter(typeof(SomeEnumConverter))]
  public SomeEnum Value

This occurs because your custom type converter does not override GetStandardValuesSupported and GetStandardValues.  These need to look something like this:

    public override StandardValuesCollection GetStandardValues(ITypeDescriptorContext context)
    {
      return new StandardValuesCollection(Enum.GetValues(typeof(SomeEnum)));
    }

    public override bool GetStandardValuesSupported(ITypeDescriptorContext context)
    {
      return true;
    }

Normally you don't need to worry about this because the CLR creates a type converter for the enum type, and that CLR-provided type converter implements these methods for you.  However when you apply TypeConverterAttribute you prevent the CLR from providing this default type converter, so you need to implement these methods yourself.

By the way, this may just be something you didn't mention, but don't forget to override CanConvertFrom and ConvertFrom as well, otherwise the grid won't be able to translate back from the UI representation to the enum value.
