Repeater控件的嵌套使用

1.前台代码：

<asp:Repeater ID="OrderList" runat="server" 
            onitemdatabound="OrderList_ItemDataBound">
        <ItemTemplate>
        <div class="item">
        <table class="table" style=" border:1px solid #DDCCCC;; border-right:none;" cellspacing="0" cellpadding="0">
<tr><td rowspan="2" colspan="5"><h1>益农乐游农品清单</h1></td><td>发货单号：</td><td colspan="3"></td></tr>
<tr><td>时间：</td><td colspan="8"></td></tr>
<tr><td >订单号：</td>
<td colspan="4"><%#Eval("orderCode")%></td>
<td>下单时间：</td>
<td colspan="3"><%#Eval("ordertime")%></td></tr>
<tr><td >收货人：</td><td><%#Eval("consignee")%></td><td>地址：</td><td colspan="6" style=" text-align:left;"><%#Eval("address")%></td></tr>
<tr><td >电话：</td><td colspan="8" style=" text-align:left"><%#Eval("mobile")%></td></tr>
<tr><td colspan="9">&nbsp;</td></tr>
<tr><td>序号</td><td colspan="5">农品描述</td><td>单价</td><td>数量</td><td>金额</td></tr>
<asp:Repeater runat="server" ID="detailOrder">
  <ItemTemplate>
  <tr><td><%#Eval("rowID")%></td>
  <td colspan="5" class="tr" style=" text-align:left"><%#Eval("Name")%></td>
  <td><%#Eval("UnitPrice")%></td>
  <td><%#Eval("Count")%></td><td>
  <%#Eval("TotalPrice")%></td></tr>
  </ItemTemplate>
</asp:Repeater>
<tr><td class="dd">配送费：</td><td><%#Eval("express")%></td><td class="dd">促销折扣：</td><td colspan="2" class="dd"><%#Eval("perferPrice")%></td><td class="dd">订单金额：</td><td><%#Eval("amount")%></td><td class="dd" style=" ">游游卡支付：</td><td><%#Eval("ka")%></td></tr>
<tr><td>已付款：</td><td><%#Eval("resultAmount")%></td><td>应付款：</td><td colspan="6" style="text-align:left;"><%#Eval("resultAmount")%></td></tr>
</table>
        </div>
        </ItemTemplate>
            
        </asp:Repeater>

2.后台代码：

 protected void Page_Load(object sender, EventArgs e)
        {
            if(!Page.IsPostBack)
            {
                string ids =Request.Params["ids"];
                string[] array = ids.Split(new char[] { '_' }, StringSplitOptions.RemoveEmptyEntries);
                string newids = string.Join(",", array);
                InitData(newids);
            }
        }
        public void InitData(string newids)
        {
            var _list = odpdbasicBLL.GetModelList(" ID in (" + newids + ")").Select(c => new OrderNode 
            {
                orderID=c.ID,
                orderCode = c.OrderCoder,
                ordertime = c.Created.ToString(),
                consignee = c.Consignee,
                mobile = c.Mobile,
                address =c.Address +"(" +c.PostCode+")",
                amount = string.Format("{0:.00}",c.Amount), //金额
                perferPrice ="未打折" ,//打折
                express =c.Express==0?"0.00":string.Format("{0:.00}",c.Express),
                resultAmount =string.Format("{0:.00}",Convert.ToDouble(c.Amount) -Convert.ToDouble(c.SubPrice) + Convert.ToDouble(c.Express)),
                yingAmount=c.Status==0?string.Format("{0:.00}",Convert.ToDouble(c.Amount) -Convert.ToDouble(c.SubPrice) + Convert.ToDouble(c.Express)):"0.00",
                ka="0.00"
            }).ToList();
            OrderList.DataSource = _list;
            OrderList.DataBind();
        }

        protected void OrderList_ItemDataBound(object sender, RepeaterItemEventArgs e)
        {
            if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
            {
                Repeater rep = e.Item.FindControl("detailOrder") as Repeater;//找到里层的repeater对象
                OrderNode rowv = (OrderNode)e.Item.DataItem;//找到分类Repeater关联的数据项 
                int  ID= rowv.orderID; //获取填充子类的orderID
                int i = 1;
                var _list = odpddetailBLL.GetModelList("OrderID=" + ID).Select(c => new 
                {
                    rowID=i++,
                    Name=c.Name+"("+c.ProNameStr+")",
                    UnitPrice=c.UnitPrice,
                    TotalPrice=c.TotalPrice,
                    Count=c.Count,

                }).ToList();
                rep.DataSource =_list;
                rep.DataBind();
            }
        }

3.说明：

因为数据是model类型的所以在

 OrderNode rowv = (OrderNode)e.Item.DataItem;//找到分类Repeater关联的数据项 

是转成model类型，若是数据是table类型，那么在此就应该是

 DataRowView rowv = (DataRowView)e.Item.DataItem;//找到分类Repeater关联的数据项
