repeater嵌套以及合计问题

大家好，又见面了，我是你们的朋友全栈君。

这次是做免费品订单的详情页面，根据需求，要做如下展示

看着还行，就是repeater里面嵌套一个repeater呗，因为之前做过类似的，代码实现不是什么大问题，存储过程也都可以搞定，第二层的repeater这么绑定就可以了

protected void rptSapOrderList_ItemDataBound(object sender, RepeaterItemEventArgs e)
        {

            if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
            {
                Repeater rep = e.Item.FindControl("rptSapOrderDetail") as Repeater;
                Model.FreeGoodsDetail md = (Model.FreeGoodsDetail)e.Item.DataItem;

                List<Model.FreeGoodsDetail> list = biz.GetOrderReceiptInfo(md.PurchaseOrderNo, md.CustCode, md.DeliveryNo);
                rep.DataSource = list;
                rep.DataBind();
            }
        }

问题是需要第一层的repeater内显示第二层的合计数，以及记录的条数，经过单MM的帮助，存储过程里求出来即可

SELECT DISTINCT CustCode
			  , CustName
			  , PurchaseOrderNo
			  , SapOrderNo
			  , DeliveryNo
			  , DeliveryDate
			  , SUM(OrderQuantity) AS  TotalAmount
			  , COUNT(*) AS TotalCount
			  , CASE ISDATE(SapOrderDate) WHEN 1 THEN CONVERT(CHAR(10), CAST(SapOrderDate AS DATETIME),121) ELSE SapOrderDate END AS SapOrderDate 
	FROM OrderReceiptInfo
	WHERE PurchaseOrderNo=@PurchaseOrderNo AND CustCode=@CustCode
	GROUP BY CustCode,CustName, PurchaseOrderNo, SapOrderNo, DeliveryNo, DeliveryDate,SapOrderDate 	

基本就这样了，好了又该忙了，妈蛋啊
