(二)代码
   1.前台界面代码:
       <%@ Page language="c#" Codebehind="WebForm1.aspx.cs" AutoEventWireup="false" Inherits="数据绑定控件同时显示主表和子表数据.WebForm1" %>
<%@ Import Namespace="System.Data" %>


 
  WebForm1
  
  
  
  
 
 
  
   
   
    
         
    
                    
    
     

<%# DataBinder.Eval(Container.DataItem,"TypeID") %>                  <%# DataBinder.Eval(Container.DataItem,"TypeName") %>                                ' runat="server">                                                                                     <%# DataBinder.Eval(Container.DataItem,"[/"TypeID/"]") %>                          <%# DataBinder.Eval(Container.DataItem, "[/"TypeDetail/"]")%>
