RadioButtonGroupByIndex

Use

The RadioButtonGroupByIndex UI element can display a number of RadioButtons groups in columns and rows. Unlike UI element CheckBoxGroup, this UI element allows user to select one element only.

The two RadioButtonGroup UI elements RadioButtonGroupByIndex 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 texts attribute, which is attached to a node with cardinality 0..n or 1..n.

Data Binding

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

Accessibility

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

Dynamic Programming
