3. RadioButton Control
- Radio Button control is used, when you want the user to
select only one option from the available choices.
- Radiobutton is used to allow user to select a single
radiobutton from group of radiobutton. In a asp.net
generally we use more than one radiobutton and select
only one radiobutton at a time from all the radiobutton
control.

6. Important Properties of the Radio Button Control
AutoPostBack - Set this property to true, if you want the webform to
be posted immediately when the checked status of the radio button
changes.
Group Name - By default, the individual radio button selections, are
not mutually exclusive. If you have a group of radio buttons, and if
you want the selections among the group to be mutually exclusive,
then use the same group name for all the radio button controls.
