For information on the individual members of this class, see RadioButtonList in the class library.

The RadioButtonList control renders a single-selection radio button group that can be dynamically generated by binding to a data source. It contains an Items collection with members that correspond to individual items on the list. To determine which item is selected, test the SelectedItem property of the list.

You can specify the rendering of the list with the RepeatLayout and RepeatDirection properties. If RepeatLayout is set to RepeatLayout.Table ( the default setting ), the list will be rendered within a table. If it is set to RepeatLayout.Flow, the list will be rendered without any tabular structure. By default, RepeatDirection is set to RepeatDirection.Vertical. Setting this property to RepeatDirection.Horizontal will render the list horizontally.

NOTE: You can also use the RadioButton control. The RadioButtonList control is easier for creating a set of radio buttons using data binding, while an individual RadioButton control gives you greater control over layout.
