You apply the EnumDataTypeAttribute attribute to a property when the property represents an enumeration type that is not available in the data source. For example, you may store a value as an integer in your database, but you want to associate that integer to an enumeration value in your application. When you apply the EnumDataTypeAttribute attribute to a property, you provide the type of the enumeration you want to associate with the property.

If the value of the property is null or an empty string (""), the value will not fail validation for the EnumDataTypeAttribute attribute. To validate that the value is not null or an empty string, use the RequiredAttribute attribute.
