RadioButton  

Definition

The RadioButton UI element is a button with two states (on/off) that enables users to select options. The RadioButton allows you to spread the displayed radio buttons individually on the screen instead of grouping them in a table. You can toggle the radio button when you bind the UI elements to the same context attribute.

The radio button is selected if the context attribute to which the selectedKey property is bound  contains the value of the key that belongs to this radio button. The key is specified by property keyToSelect.
