Repeater 嵌套的问题

Question

有一个商品订单的IList泛型类,我现在要把商品订单全部呈现出来,
IList<Order> orderList=new List<Order>();//声明
orderList=GetOrderList();//获取订单列表
repeater.DataSource=orderList;//绑定到repeater控件但是orderList类下还有一个成员,orderList.ProductList,这个成员变量是IList类型,是指订单里的产品列表,也就是说一个产品订单里有多个商品.
现在我要把它们用嵌套Repeater显示出来,大家给个方法
示意图如下:                          订单一用户名:XX
运送地址:XX
产品列表:
产品1
产品2
……                          订单二用户名:XX
运送地址:XX
产品列表:
产品1
产品2
……

Answer 1

不一定用欠套吧，你可以在鼠标移动到某个订单时，弹出一个悬浮的DIV 来显示商品列表嘛

Answer 2

 所有的订单是一个Repeater,每个订单的产品列表是个Repeater 订单一 用户名:XX 
运送地址:XX 
产品列表: 
产品1 
产品2 
……                                                     订单二 用户名:XX 
运送地址:XX 
产品列表: 
产品1 
产品2 
…… 

Answer 3

嵌套就嵌套啦<repeater>
 <itemtemplate>
     用户名:<%# Eval("X") %>
     运送地址:<%# Eval("X") %>
     产品列表:<%# Eval("X") %>
     <repeater>
          <itemtemplate>
               产品<%# Eval("X") %>////楼主是不是在这里不知道绑定谁?怎么绑定了? 因为数据源不定？
          </itemtemplate>
     </repeater> 
 </itemtemplate>
</repeater>

Answer 4

 产品 <%#   Eval("X")   %> ////楼主是不是在这里不知道绑定谁?怎么绑定了?   因为数据源不定？ 这个数据源就是orderList.ProductList,但是不知具体如何写了

Answer 5

给你一个实例吧  照着做即可,我这里的Repeater1 中嵌套了RadioButtonList 注意用到了   DataSource='<%# ((System.Data.DataRowView)Container.DataItem).CreateChildView("myrelation") %>'做嵌套记录集,后台注意
  ds.Relations.Add("myrelation",
        ds.Tables["questions"].Columns["id"],
        ds.Tables["answers"].Columns["questionsid"]);        //Bind the Authors table to the parent Repeater control, and call DataBind.
        Repeater1.DataSource = ds.Tables["questions"];
        Page.DataBind();
建立父子关系
 <asp:Repeater ID="Repeater1" runat="server" OnItemDataBound="Repeater1_ItemDataBound">
            <HeaderTemplate>
            </HeaderTemplate>
            <ItemTemplate>

                    <%#Container.ItemIndex + 1%>
                    .</a><asp:Label ID="Label1" runat="server" Text='<%# Eval("subject") %>'></asp:Label>

Answer 7

关键就是这一段    protected void Repeater1_ItemDataBound(object sender, RepeaterItemEventArgs e)
    {
        Trace.Warn("Repeater1_ItemDataBound");
        System.Web.UI.WebControls.Repeater repeater2 = (System.Web.UI.WebControls.Repeater)e.Item.FindControl("Repeater2");
        repeater2.DataSource = ((Order)e.Item.DataItem).ProductList;
        repeater2.DataBind();
        
    }
e.Item.FindControl这一句,找到Repeater2,因为Repeater2的实际ID是变化的,所以需要这样找到他,嘻嘻
然后进行数据 绑定
((Order)e.Item.DataItem).ProductList;这一句找到当前条目所对应的数据            <asp:Repeater ID="Repeater2" runat="server" OnItemDataBound="Repeater2_ItemDataBound">
                <ItemTemplate>
                <p>&nbsp;&nbsp; 产品<%# Container.DataItem %></p>
                </ItemTemplate>
            </asp:Repeater><%# Container.DataItem %>
这个语句,楼主自己斟酌斟酌..呵呵

Answer 8

HTML代码中,,去掉OnItemCreated="Repeater1_ItemCreated"呵呵,自己乱加的

Answer 9

效果如下
用户名:UserA地址:UserA.Address产品列表   产品UserA1   产品UserA2   产品UserA3用户名:UserB地址:UserB.Address产品列表   产品UserB1   产品UserB2   产品UserB3希望能解决楼主的问题

@bingdian37 
<asp:Repeater ID="Repeater2" runat="server" OnItemDataBound="Repeater2_ItemDataBound">
可以在上面直接指定DataSource 的

怎么把这一句也去掉呢??    protected void Page_Load(object sender, EventArgs e)
