asp.net基于donetCHARTING的自动报表

1，首先需要添加引用ChartExtents.dll和donetCHARTING.dll，资源百度大把。

2，配置图片生成类。

3，新建一个ASP.NET页面，前台代码如下：

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Statistics.aspx.cs" Inherits="ting.Views.Statistics" %><%@ Register Assembly="dotnetCHARTING" Namespace="dotnetCHARTING" TagPrefix="dotnetCHARTING" %><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml"><head runat="server">    <title></title></head><body>    <form id="form1" runat="server">        <div>            <dotnetCHARTING:Chart ID="Chart1" runat="server">            </dotnetCHARTING:Chart>        </div>        <p>            请选择报表类型：<asp:DropDownList ID="DropDownList1" runat="server" AutoPostBack="True"                OnSelectedIndexChanged="DropDownList1_SelectedIndexChanged">            </asp:DropDownList>        </p>    </form></body></html><script type="text/javascript">    var obj = document.getElementsByTagName("map")[0];    obj.parentNode.removeChild(obj); //屏蔽隐藏的链接</script>

后台代码如下：
