索引将所有单选按钮状态存储在数组中，然后从数组存储到会话，然后每当加载相同页面时，将所有控件状态从会话加载到数组，并从数组加载所有控件状态以设置单个控件状态.

when you change the page index store all the radio button state in an array,then from array to session, then whenever you load the same page back load all the control state back from session to array and from array to set the individual control state.
