CheckBoxGroup 

The CheckBoxGroup enables the user to select one element from a set of options checking it. The UI element CheckBoxGroup arranges the individual CheckBoxes in single-column or two-column tables.

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

Data Binding

A CheckBoxGroup is a multiple selection displayed as a group of checkboxes on the screen.

The view context must provide the node X that can contain 0 to n values (cardinality=0..n). The context node must contain an attribute y that provides the texts for the checkbox fields. The data type of the context attribute y can be any simple data type – for example, String, int, and so on. The number of checkboxes equals the number of node elements. The selection of the checkboxes is determined by the multiple selection of the node. The texts property of the CheckBoxGroup UI element is bound to the attribute y by assigning the context path of the context y to the texts property.

For more information about the structure of context structures see Context. For information about the data binding model see Data Binding and Mapping, Data Binding and Data Binding of UI Element Properties.

Example

You can find examples of this interface element in the system in the Web Dynpro application WDR_TEST_UI_ELEMENTS, and in the component WDR_TEST_EVENTS in the view CheckboxGroup.
