[导入]GridView中实现并列排名的例子

Access数据库版本

<%@ Page Language="C#" AutoEventWireup="true" Debug="true" %>
<%@ Import Namespace="System.Data" %>

public int TrapezoidIndex = 1;

//ASPNET20Book.mdb数据库参见《ASP.NET 2.0应用开发技术》一书的光盘

System.Data.OleDb.OleDbConnection cn = new System.Data.OleDb.OleDbConnection(ConnectionString);

<%#Container.DataItemIndex + 1%>

<%#Eval("UserName")%>

<%#Eval("Shuxue")%>

<%#TrapezoidIndex%>
