To add a barcode to a report, simply drag the Barcode component from the Report Design Palette on to your Design panel workspace. You will see a placeholder barcode with its driving data key displayed, and a description of the encoding for the type specified in the Barcode Format field of the Configure Barcode tab. Data Keys can be dropped or typed into the DataKey field, and the driving key will be shown in its appropriate barcode placeholder. The actual barcode, as well as any text to be displayed under the barcode, is generated and rendered when the report is executed or previewed.
Barcodes require a Data Key or Text to encode. Note, that each Barcode Format encoder has specific requirements for what it will encode. Barcode Format Info displays some brief information about the selected format, but is not comprehensive.
