关于RadioButtonList的问题
<asp:RadioButtonList id="PayType" runat="server" Width="120px"><asp:ListItem Value="1"> 现金支付</asp:ListItem><asp:ListItem Value="2"> Ｅ币支付</asp:ListItem><asp:ListItem Value="3"> 经验值支付</asp:ListItem>
</asp:RadioButtonList>
我在.cs文件中有这样的要求，当用户现金不足时，
“现金支付”这个选项呈灰色，不可选，怎么实现啊

只能用JavaScript实现，实现代码楼上几位已回复，提醒注意的就是用JS设置的样式要页面第次回发时都要设置一下，因为JS的设置不会保存控件的状态Top
