Repeater嵌套Repeater的结构：一般写过的都能看懂吧

    private void RpTypeBind()
    {
        //GetQuestionTypeAndCount() 返回一个datatable
        this.rptypelist.DataSource = LiftQuestionCtr.GetQuestionTypeAndCount();
        this.rptypelist.DataBind();
    }
    protected void rptypelist_ItemDataBound(object sender, RepeaterItemEventArgs e)
    {

        //判断里层repeater处于外层repeater的哪个位置（ AlternatingItemTemplate，FooterTemplate，
        //HeaderTemplate，，ItemTemplate，SeparatorTemplate）
        if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
        {
            Repeater rep = e.Item.FindControl("rpquestionlist") as Repeater;//找到里层的repeater对象
            DataRowView rowv = (DataRowView)e.Item.DataItem;//找到分类Repeater关联的数据项 
            int typeid = Convert.ToInt32(rowv["qtid"]); //获取填充子类的id 
            rep.DataSource = LiftQuestionCtr.GetSomeQuestionsByTypeid(typeid, 2);
            rep.DataBind();
        }
    }
