if you press browser refresh button it is not possible to retain values.

hi urtrivedi.ya wat you said was right..is it posible for disabling browser refresh button using java script.

You can use HTML5's localStorage/ Cookie if you want it to be retained. you can do the following steps

1. Passively/Actively save the option value to localStorage/cookie
2. Refresh
3. Check which radio button was selected, then put a "checked" tag

Here's some reference to get you up and running:
HTML 5 - Local Storage

Hi ritanji,
It's possible to disable the refresh button. You can filter it on the keydown event, it has a keycode of 116.
