解决 ASP.NET Chart 控件出错 为 ChartImg.axd 执行子请求时出错

最简单的解决办法是用Beyond compare 比较一下你建立的web.config同网站下载的例子直接的不同。然后直接复制过去就OK。关键一点是建立TempImages目录

1. 修改web.Config

发现有时候直接拖动控件进入可能在web.config里面配置会减少

1。请添加 TempImages目录在网站根目录，当然可以其他名字，如果其他名字请修改下面的名字

2.添加下面

<appSettings>
      <add key="ChartImageHandler" value="Storage=file;Timeout=20;Url=~/TempImages/;"/>
</appSettings>

3.在<controls>....</controls> 中添加        

<add tagPrefix="asp" namespace="System.Web.UI.DataVisualization.Charting" assembly="System.Web.DataVisualization, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>

4.在<httpHandlers>...</httpHandlers>添加

      <add path="ChartImg.axd" verb="GET,HEAD" type="System.Web.UI.DataVisualization.Charting.ChartHttpHandler, System.Web.DataVisualization, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" validate="false"/>

5.在 下面主意送色字体，没有加上

<system.webServer>
   <validation validateIntegratedModeConfiguration="false"/>
   <modules>
    <remove name="ScriptModule"/>
    <add name="ScriptModule" preCondition="managedHandler" type="System.Web.Handlers.ScriptModule, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
   </modules>
   <handlers>
    <remove name="WebServiceHandlerFactory-Integrated"/>
    <remove name="ScriptHandlerFactory"/>
    <remove name="ScriptHandlerFactoryAppServices"/>
    <remove name="ScriptResource"/>
      <remove name="ChartImageHandler"/>
    <add name="ScriptHandlerFactory" verb="*" path="*.asmx" preCondition="integratedMode" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
    <add name="ScriptHandlerFactoryAppServices" verb="*" path="*_AppService.axd" preCondition="integratedMode" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
    <add name="ScriptResource" preCondition="integratedMode" verb="GET,HEAD" path="ScriptResource.axd" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
      <add name="ChartImageHandler" preCondition="integratedMode" verb="GET,HEAD" path="ChartImg.axd" type="System.Web.UI.DataVisualization.Charting.ChartHttpHandler, System.Web.DataVisualization, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
   </handlers>
</system.webServer>
