       }

       public override bool GetStandardValuesExclusive(
                      ITypeDescriptorContext context)
       {
           // returning false here means the property will
           // have a drop down and a value that can be manually
           // entered.
           return true;
       }

       public override StandardValuesCollection GetStandardValues(
                     ITypeDescriptorContext context)
