I think you should set the Text of the barcode view itself instead of the text of the barcode of the barcode view, so:

TfrxBarCodeView(barcode).Text := value;

instead of

TfrxBarCodeView(barcode).BarCode.Text := value;

Tried to add a reference, but online documentation seems to be non-existent. But I bumped into this snippet on the FastReports forum, and this one in some, I don't know, website. Both are using TfrxBarCodeView.Text rather than TfrxBarCodeView.Barcode.Text.
