RadioButtonGroupByKey 

The RadioButtonGroupByKey UI element groups multiple RadioButtons in a table. Unlike UI element CheckBoxGroup, this UI element allows user to select one element only.

Example of the Visual Display

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

To enable the development of accessible applications, the accessibilityDescription property is checked during the syntax check if the tooltip property is not set.

 

Runtime Class

Events in View Designer

Name

onSelect

Other properties that can be inherited are defined in the associated higher-level classes. The associated UI elements are:

●        MenuItem

●        ViewElement

Data Binding

The values for the DropDownByKey are determined from the value set of the attribute bound to the property selectedKey. If the attribute has an ABAP Dictionary type and if fixed domain values are defined for this type, these values are used. The text for the respective value is displayed in the list and in the DropDownByKey field.

See Data Binding within Web Dynpro generally, and Data Binding of UI Element Properties, and Data Binding Using Keys.

Dynamic Programming

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