Name
RadioButton
Synopsis
This Control
provides a means of selecting one of
a set of mutually exclusive options. (Compare this with a set of
CheckBox
objects that may all be selected
simultaneously.) All the RadioButton
objects
within a single container act as a single exclusion group. Therefore,
to have several independent groups on the same parent
Control
, you must place them in different
containers. Panel
or GroupBox
objects will do the job.
You can change the Appearance
of the control from
the Normal
dot with a label to a
Button
-like style. In the
Normal
view, the position of the
RadioButton
relative to the label can be modified
with the CheckAlign
property.
As with the CheckBox
, you can determine whether
the item is Checked
(although it does not have an
equivalent of the CheckBox.CheckState
property, as
there is no tristate support). You can also enable
AutoCheck
to ensure that the system automatically
checks the selected button and unchecks the others in the group. You
can bind to the CheckedChanged
event to be
notified when the Checked
state changes.
