RadioButtonGroupByIndex 

The RadioButtonGroupByIndex UI element represents a number of radio buttons groups in columns and rows. Unlike UI element CheckBoxGroup, this UI element allows user to select one element only.

Example of the Display

The dropdown list box UI elements, RadioButtonGroup and RadioButtonGroupByKey, do not differ from each other when displayed on the screen. JHowever, the data binding model for the RadioButtonGroupByKey UI element has a completely different concept (see section Data Binding).

If the tooltip property has not been set, the property accessibilityDescription is checked during the design time to ensure Accessibility.

onSelect

Further properties that can be inherited are defined in the associated higher-level class.  The associated interface elements are:

●      UIElement

●      ViewElement

Data binding

The property text must be bound to a context attribute that lies within a context node with the cardinality 0..n or 1. For each element of this node a RadioButton with the respective value of the text attribute is displayed as a text.

See Data Binding within Web Dynpro generally, and Data Binding of UI Element Properties, and Data Binding Using an Index and Key.

Dynamic Programming

For dynamic programming the same properties, events, and aggregations are provided in the View Designer. Bear in mind the different spellings.
