RadioButtonGroupByIndex (SAP Library

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 Visual Display

This graphic is explained in the accompanying text

The dropdown list box UI elements, RadioButtonGroup and RadioButtonGroupByKey, 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). The displayed texts are taken from the attribute text which is attached to a node with the cardinality 0..n or 1..n.

Note

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

CL_WD_RADIOBUTTON_GROUP_BY_IDX

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.

Note

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

· UIElement

· ContextMenuProvider

· ViewElement

Dynamic Programming

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