Repeater 嵌套的问题

zhou_she 2008-02-29 10:09:17

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
……

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

HTML代码中,,去掉OnItemCreated="Repeater1_ItemCreated"

呵呵,自己乱加的

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>   产品<%# Container.DataItem %></p>

                </ItemTemplate>

            </asp:Repeater>

<%# Container.DataItem %>
这个语句,楼主自己斟酌斟酌..呵呵

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
