The XamBarcode™ control exposes the following events:
The ErrorMessageDisplayingEventArgs object’s ErrorMessage property allows you to get or set the error message. The DataChangedEventArgs object’s NewData property conveniently allows you to get the value of the XamBarcode control’s Data property that has just been changed.
You will handle the DataChanged and ErrorMessageDisplaying events .
Add a XamBarcode control to your page . For more info on this, see Adding Barcode Using XAML Code or Adding Barcode In Code-Behind .
