Alternatively, if it is a ASP.ENT application, then he can use the Page's
FindControl method to return the actual radiobutton given it's name.
The efficiency of which method to use would depend on the number of other
controls on the page. If there are many non radio buttons, or that only some of
the radio buttons information is required in the given code block, or they need
to be retrieved in a given order, then using FindControl would be preferable. If
there are mainly only radiobuttons and all of them need to be enumerate through
in no given order, then using the control's collection would be preferable.
