BarCode Basics

The BarCode control itself has several options like borders and a caption that can be used to wrap its symbology presentation.

Border Around the Bar Code

The BarCode inherits Control and therefore has several border-related properties such as BorderBrush and BorderThickness. Set those properties to add a border around the bar code.

We also have added a CornerRadius property that can be used to round off one or more of the corners. It accepts a standard CornerRadius.

Caption Above the Bar Code

Normally the bar code's value is displayed below the bar code. You can also display content above the bar code.

For instance, perhaps you wish to show some text indicating what the bar code is for.

The Caption property can be set to add a caption. The property accepts any object so you can use text or another UIElement and it will be centered above the bar code, but within the bar code's outer border, if any.

Setting a Symbology

Each bar code symbology is implemented in a separate .NET type. For instance, Code 39 is implemented by the Code39Symbology class.

Set the symbology that you would like to use for your bar code to the BarCode.Symbology property.

See the Symbologies topic for a list of the available symbologies.

Setting the Value to Encode

You set the value to encode directly on the BarCodeSymbology class instance that you assign to the BarCode. This is done via the Value property.

Rotating or Scaling the Bar Code

Since BarCode is a Control, you can apply RotateTransform and ScaleTransform objects to its LayoutTransform and RenderTransform properties.

Changing Symbology Options

Each symbology has its own options. Although many share some common options such as BarHeight or ValueDisplayStyle, others like Code39Symbology have extended options such as AreStartStopCharactersVisible and IsChecksumEnabled.

See the documentation for each symbology to learn what options are available.
