I am trying to figure out how to clear a textbox field when a radiobutton list is deselected. So I have 3 radiobuttons and textbox field and say when user check Radiobutton#1 and enters value in the textbox but then decides they wnat to select Radiobutton#2 how to clear the value out of textbox that is in Radiobutton#1. I tried using onchange, onfocus events but they don't seem to work.
