Example

HTMLInputRadiobutton
Declare three HtmlInputRadioButton controls, one HtmlInputButton control, and one HtmlGeneric control in an .aspx file (remember to embed the controls inside an HtmlForm control). When the submit button is triggered, the submit subroutine is executed. The submit subroutine may respond in three ways: if the radiobutton with id="r1" is selected, the server sends the message "Your favorite color is red" to the p element. If the radiobutton with id="r2" is selected, the server sends the message "Your favorite color is green" to the p element. If the radiobutton with id="r3" is selected, the server sends the message "Your favorite color is blue" to the p element.
