asp.net - java script for radiobuttonlist select and deselect -

I have radio button list control in which the data is coming from DB and is bidding in a .cs file

Now I have to write a Javascript that if the user selects item 1 in the Radiobutton list, then it is selected and then the user clicks on a single item then deselect it.

Even if I have 10 items, then this should be selected and deselecting the item's churn on it

thanks
