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>
  
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>
