1：现在在datalist中绑定一个radiobuttonlist，如何给这个radiobuttonlist绑定数据源？
如何获取这个radiobuttonlist的选定值？
我这样写：
radiobuttonlist dd = (radiobuttonlist)e.item.findcontrol("ddd");
string cc=dd.selectvalue.tostring();
但程序提示：未将对象引用到实例
2：如何当我在删除datalist中一行的时候给一个提示是否要删除
谢谢各位大虾了，我没有分了，要不多加点在线等！！！

2--也是在ItemDataBound里写
LinkButton lb=(LinkButton)e.item.findcontrol("..");
if(lb!=null)
{
lb.Attributes["onclick"]="<script language=javascriopt>confirm(\"真的删除吗?\");</sript>"
}
{
if(e.Item.ItemType==ListItemType.Item || e.Item.ItemType==ListItemType.AlternatingItem)
{
Button btn=e.Item.FindControl("Button") as Button;
btn.Attributes.Add("onclick","javascript:window.event.returnValue=window.confirm('Delete?');");
//设置删除提示
RadioButtonList rbl = e.Item.Findcontrol("RadioButtonList1") as RadioButtonList;
rbl.DataSource=??;
rbl.DataTextField=??;
rbl.DataValueField=??;
rbl.DataBind();
//设置数据源
}
}
