property OnInvalidLength: TOnInvalidLength;

Parameters:

• Sender: TObject; It is the object whose event handler is called.
• Barcode: String; The invalid value of the Barcode property. For the TBarcode_OneCode component, first 20 characters are the Tracking (It is right padded with zeroes to 20 characters), then come the Routing.
