子级Repeater获取父级Repeater绑定项的值

1.子级Repeater中绑定父级的某个字段：

<%# DataBinder.Eval((Container.NamingContainer.NamingContainer as RepeaterItem).DataItem, "ModuleName") %>

2.在子级Repeater中引用父级某个控件的值：

<%# ((Label)((RepeaterItem)((Repeater)(((RepeaterItem)Container).NamingContainer)).NamingContainer).FindControl("moduleID")).Value %>

<asp:Repeater ID="Repeater1" runat="server"> 
     <ItemTemplate> 
        OrderID: <%# Eval("OrderID")%>
        CustomerID : 
         <asp:Label ID="Label1" runat="server" Text='<%#Eval("CustomerID")%>'></asp:Label> <br />
        <asp:Repeater ID="Repeater2" runat="server" DataSource='<%# GetOrderDetails(Convert.ToInt32(Eval("OrderID"))) %>'> 
            <ItemTemplate>  
                &nbsp;&nbsp;
                子容器得到CustomerID : <%# ((Label)((RepeaterItem)((Repeater)(((RepeaterItem)Container).NamingContainer)).NamingContainer).FindControl("Label1")).Text %> 
                UnitPrice: <%#Eval("UnitPrice")%> <br />
            </ItemTemplate> 
        </asp:Repeater> 
        <br />                 
     </ItemTemplate> 
</asp:Repeater>
