The ASPxRadioButtonList editor is a radio button group that provides end-users with the ability 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 manually populating the Items collection. For each list item, you can specify its caption and associated value.
The item selected within ASPxRadioButtonList can be determined by iterating through list items and inspecting an item's Selected property or by using specific properties declared at the editor level (SelectedItem, SelectedIndex). You can easily manipulate a select item on the client side by using specific client methods (GetSelectedItem/SetSelectedItem, GetSelectedIndex/SetSelectedIndex).
The ASPxRadioButtonList layout is flexibly customized. You can display radio button items in several columns (RepeatColumns), set a direction of items within the editor (horizontal or vertical through the RepeatDirection property), and specify whether items are aligned within a table or rendered without any table structure (RepeatLayout).
