A Radio Group control provides a collection of radio buttons for the user to choose from. It enables you to create a single control that contains a row by column array of radio buttons. The default for a Radio Group is one column and two rows.

In a Web Radio Group control, the number of rows and columns is controlled by the ColumnCount and RowCount properties in the Inspector. Change these properties as necessary and then resize the control so that everything fits properly.

To edit the cells of a Radio Group, use the Set Default Value feature. Once active, you can click on each cell to set its properties (Caption, Enabled, Visible, Tag and Selected).
