The DevExpress ASP.NET Radio Button List (ASPxRadioButtonList) editor is a radio button group that allows end-users to select a single item at a time. Its contents can be generated dynamically by binding the editor to a data source. You can also create items explicitly by populating the Items collection manually. For each list item, you can specify its caption and associated value.
The item selected within ASPxRadioButtonList can be determined by using specific properties declared at the editor level (SelectedItem, SelectedIndex). You can easily get and set the selected item on the client side using specific client methods (GetSelectedItem/SetSelectedItem, GetSelectedIndex/SetSelectedIndex).
The ASPxRadioButtonList layout can be flexibly customized. You can display radio button items in several columns (via the RepeatColumns property), set the direction of items within the editor (horizontal or vertical, via the RepeatDirection property), and specify whether items are aligned within a table or rendered without any table structure (via the RepeatLayout property).
