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.
