To start using RadBarcodeView just drag it from the toolbox and drop it at the form.
The default Symbology is QRCode and the initial value is 12345.
After choosing the desired Symbology you can further adjust its specific settings if available:
The value which is encoded is set through the Value property.
The width (size) of the bar-code elements is auto calculated from the size of the control.
By default, RadBarcodeView uses black color to draw the bar-code elements. You can customize it by the ForeColor property.
