Function DDFieldValidate Returns Integer
| Call: | Get DDFieldValidate to IntegerVariable |
DDFieldValidate performs a DataDictionary object (DDO) field validation for the data column bound to this data entry object (DEO) (data-binding is done with the Entry_Item command). It returns 0 if no error. If an error is encountered, a validation error may be displayed and a non-zero value returned. This message is sent by the OnValidate event.
You will not use this often. Normally, validation occurs automatically as needed - during forward keyboard navigation and before a save. If you wish to trigger a custom validation, you should probably send OnValidate. If you wish to create a custom validation rule, you should augment your DD class or DD object. If you wish to create a custom validation rule outside of your DDO, you should augment OnValidate.
