Enable or disable required field validator controls

Hi,

       I have a listbox and a radiobuttonlist control.I have required field validator controls for radiobuttonlist and listbox.

If an option is selected in the radiobuttonlist control,then the required field validator control for the listbox should be disabled.

If an item is selected in the listbox control,then the required field validator control for the radiobuttonlist control should be disabled.

I would like to do this in javascript.I am not sure how to iterate the radiobuttonlist control or listbox in javascript.

I am not sure how to code for this.Please guide me.

Thanks,

pcs
