TRadioButton displays a radio button on the page.
You can specify the caption to display beside the radio buttonby setting
the {@link setText Text} property. The caption can appear either on the right
or left of the radio button, which is determined by the {@link setTextAlign TextAlign}
property.
To determine whether the TRadioButton component is checked, test the {@link getChecked Checked}
property. The {@link onCheckedChanged OnCheckedChanged} event is raised when
the {@link getChecked Checked} state of the TRadioButton component changes
between posts to the server. You can provide an event handler for
the {@link onCheckedChanged OnCheckedChanged} event to to programmatically
control the actions performed when the state of the TRadioButton component changes
between posts to the server.
TRadioButton uses {@link setGroupName GroupName} to group together a set of radio buttons.
Once the {@link setGroupName GroupName} is set, you can use the {@link getRadioButtonsInGroup}
method to get an array of TRadioButtons having the same group name.
If {@link setAutoPostBack AutoPostBack} is set true, changing the radio button state
will cause postback action. And if {@link setCausesValidation CausesValidation}
is true, validation will also be processed, which can be further restricted within
a {@link setValidationGroup ValidationGroup}.
Note, {@link setText Text} is rendered as is. Make sure it does not contain unwanted characters
that may bring security vulnerabilities.
