Specifies the field from which the TDBBarcode component represents barcode symbol.
property DataField: string;
Use DataField to bind the TDBBarcode component to a field in the dataset. To fully specify a database field, both the dataset and the field within that dataset must be defined. The DataSource property of the TDBBarcode component specifies the dataset which contains the DataField. The DataField should be specifed as a string field.
When a barcode component is linked to the TDBBarcode component, except the TBarcode_FIM and TBarcode_OneCode components, the database field value will be applied to its Barcode property. If a TBarcode_FIM component is linked to the TDBBarcode component, The first character of the data field value will be applied to its FIMType property. If a TBarcode_OneCode component is linked to the TDBBarcode component, the database field value will be applied to its Tracking and Routing properties, the first 20 characters are the Tracking (It is right padded with zeroes to 20 characters), then come the Routing.
You can bind multiple TDBBarcode components to one database field in order to represent the database field with multiple barcode symbols.
