Hi; When a user clicks a radio button, what I would like to do is that if javascript is enabled on their browser, it calls a javascript function and does not do a postback. If javascript is disabled, then it does do a postback. Is there a way to do this? -- thanks - dave david_at_windward_dot_net www.windwardreports
