Example
Radiobutton
In this example, we declared three RadioButton controls in the .aspx file, A Button control, and a Label control. When the submit button is triggered, the submit subroutine is executed. The submit subroutine will respond in three ways: if the radiobutton with the id="red" attribute is selected, the server sends the message "You selected Red" to the Label control; if the radiobutton with the id="green" attribute is selected If selected, the server sends the message "You selected Green" to the Label control; if the radiobutton with the id="blue" attribute is selected, the server sends the message "You selected Blue" to the Label control.
