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

Further properties that can be inherited are defined in the associated higher-level class. The associated interface elements are:
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.
For dynamic programming the same properties, events, and aggregations are provided in the View Designer. Bear in mind the different spellings.
