        protected void rpt_Level02_ItemDataBound(object sender, RepeaterItemEventArgs e)
        {
            if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
            {
                Repeater rpt = (Repeater)e.Item.FindControl("rpt_Level03");
                rpt.ItemDataBound += new RepeaterItemEventHandler(rpt_ItemDataBound);//<==这里是关键
                int typeFatherID = ((CommonType)e.Item.DataItem).TypeID;
                rpt.DataSource = da.GetAllNodeInfo(tt, typeFatherID);
                rpt.DataBind();
            }
        }        protected void rpt_ItemDataBound(object sender, RepeaterItemEventArgs e)
        {
            if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
            {
                Repeater rpt = (Repeater)e.Item.FindControl("rpt_Level04");
                int typeFatherID = ((CommonType)e.Item.DataItem).TypeID;
                rpt.DataSource = da.GetAllNodeInfo(tt, typeFatherID);
                rpt.DataBind();
            }
        }

呵呵，发的是三层嵌套如果是两层看这里就够了：
        protected void rpt_ItemDataBound(object sender, RepeaterItemEventArgs e)
        {
            if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
            {
                Repeater rpt = (Repeater)e.Item.FindControl("rpt_Level04");
                int typeFatherID = ((CommonType)e.Item.DataItem).TypeID;
                rpt.DataSource = da.GetAllNodeInfo(tt, typeFatherID);
                rpt.DataBind();
            }
        }
