The Radio Button advanced control enables you to select between a collection of choices. The default output is a number that indicates the position of the selected item. A more sophisticated behavior is programmed through a script using the Radio Button class and other features of your scripting language.

To change the appearance of the Radio Button, right-click it and then select Edit > Properties.

Any settings you have programmed into the script override the settings made in the Properties tab.

In the default script for Radio Button, notice that there are four events: Start, Exec, Stop, and SelectionChange. The Exec event is where inputs and outputs can be processed, returning the state of the radio button. Procedures for formatting the radio button itself are defined in the Start event, or using the Properties tab.
