The List Validator is one of the Validations that you can add to a Column defined in the Database Repository. With the List Validator you can define:
 | A fixed set of literal values that are allowed for the column. |
| Labels that map to the literal values in the set. |
| A default value, by choosing one of the allowed values as the default. |
The values defined in a List Validator are stored in the database, the labels are used in the user interface of a generated application.
The set of allowed values is created by adding values to the list. A default value is set by checking it in the IsDefault column.
User interface implementation
A column with a List Validator is implemented as a dropdown list in the user interface of applications generated with GenWise. If the column is nullable, the dropdown list will also contain a null/empty value.
