Interleaved 2 of 5 is a high-density numerical barcode based on the Standard 2 of 5 symbology. It is used primarily in distribution and warehousing industries.

Refer to the following article for more details: Interleaved 2 of 5.

Note

Since digits are encoded in pairs, only an even number of digits can be encoded. Usually, an odd number of digits is encoded by adding “0” as the first digit.

Add the Bar Code to a Report

Drag the XRBarCode item from the DX.25.2: Report Controls tab and drop it onto the report.
Set the XRBarCode control’s Symbology property to Interleaved2of5 (an object of the Interleaved2of5Generator type).
Specify common barcode properties and properties specific to Interleaved 2 of 5.

Specific Properties

Runtime Example
