Question

描述：
我要实现的效果
一级分类A
    一级小类A1
    一级小类A2
一级分类B
    二级小类B1
    二级小类B2一级的我已经实现了，关键代码如下：

      <ItemTemplate>
  <tr>
<td height="30" background="../Images/Back/Bg_02.gif">一级分类A</td>
  </tr>
  <!--小类循环显示开坮-->

<td height="30" colspan="3" bgcolor="#FFFFFF">二级如何实现？</td>
          </tr>
  <!--小类循环显示结束-->
  </ItemTemplate>
</asp:Repeater>

Answer 1

Repeater 嵌套前台：
<asp:Repeater ID="orderList" runat ="server" >
                <ItemTemplate>
                    <table cellspacing="0" cellpadding="2" rules="all" border="1" id="Table1" style="border-color:#99CC00;border-width:1px;border-style:solid;width:100%;border-collapse:collapse;">
                    <tr>
                    <td>订单号：<%# Eval("OrderID") %></td>
                    <td>下单时间：<%# Eval("OrderDate") %></td>
                    </tr>
                    </table>
                    <asp:Repeater ID="detailList" runat ="server" >
                        <HeaderTemplate>
                            <table cellspacing="0" cellpadding="2" rules="all" border="1" id="shopList" style="border-color:#99CC00;border-width:1px;border-style:solid;width:100%;border-collapse:collapse;">
                            <tr>
                            <td align="center" style="background-color:#99CC00;">商品名称</td>
                            <td align="center" style="background-color:#99CC00;">购买价</td>
                            <td align="center" style="background-color:#99CC00;">数量</td>
                            <td align="center" style="background-color:#99CC00;">小计</td>
                            <td align="center" style="background-color:#99CC00;">图片</td>
                            </tr>
                        </HeaderTemplate>
                        <ItemTemplate>
                            <tr>
                            <td><%# Eval("FlowerName") %></td>
                            <td>￥<%# Eval("Price") %></td>
                            <td><%# Eval("Quantity")%></td>
                            <td>￥<%# Eval("UnitPrice")%></td>
                            <td><span onclick="openImg('<%#Eval("FlowerPhoto") %>');" style ="cursor :hand">查看</span></td>
                            </tr>
                        </ItemTemplate>
                        <FooterTemplate>
                            </table>
                        </FooterTemplate>
                    </asp:Repeater>
                </ItemTemplate>
             </asp:Repeater>后台：private void orderList_ItemDataBound(object sender, RepeaterItemEventArgs e)
        {
            PDSource.BLL.OrderDetails bll = new OrderDetails();            if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
            {
                Repeater detailList = (Repeater)e.Item.FindControl("detailList");
                
                
                //找到分类Repeater关联的数据项 
                DataRowView rowv = (DataRowView)e.Item.DataItem;
                //提取分类ID 
                int OrderId = Convert.ToInt32(rowv["OrderId"]);
                //根据分类ID查询该分类下的产品，并绑定产品Repeater 
                detailList.DataSource = bll.GetListBySp(1, 10000, " OrderId =" + OrderId);
                detailList.DataBind();
            } 
        }
