In the ClientEvents-OnSelectedIndexChanged would be nice if there was a way to get_oldvalue(). I do it with a hidden field but that would be helpful.

Hi David,

The RadioButtonList gives access to the old selected item index in the OnSelectedIndexChanged event, so you can used it in order to access the old item value in a similar way:

            function OnSelectedIndexChanged( buttonList, args) {
                var oldIndex = args.get_oldSelectedIndex();
                var oldItem = buttonList.get_items()[oldIndex];
                var oldValue = oldItem.get_value();
            }
