Event: OnChange

Occurs when the value of Barcode or Data (only for Delphi/C++ Builder 2009 or later) property is changed.

Syntax:

property OnChange: TNotifyEvent;

Parameters:

• Sender: TObject; It is the object whose event handler is called.

Note:

For the TBarcode2D_CCA, TBarcode2D_CCB, and TBarcode2D_CCC 2D barcode components, if the properties' value of the linear component is changed, only the OnChange event of linear component occurs. The event of TBarcode2D_CCA, TBarcode2D_CCB, and TBarcode2D_CCC components doesn't occur.
