datalist嵌套datalist,内datalis事件

 protected void DataList1_ItemDataBound(object sender, DataListItemEventArgs e)
    {
        if (e.Item.ItemType == ListItemType.AlternatingItem || e.Item.ItemType == ListItemType.Item)
        {
            DataList dl = (DataList)e.Item.FindControl("DataList2");
            DataRowView drv = (DataRowView)e.Item.DataItem;
            string id = drv["scid"].ToString();
            DataSet ds = db.dbo("select a.id,a.sadd,a.jointime,a.pasttime,a.sname,a.stype,b.aname from service a,accendant b where scid='" + id + "' and a.sid=b.aid ", "dong");
            dl.DataSource = ds;
            dl.DataBind();
        }
    }

问题是我怎么写里面的DataList2的编辑，删除事件！诚心向大家请教。
