ChartImg.axd 执行子请求时出错，主要是web.config配置问题,整理正确配置如下:<appSettings> <add key="ChartImageHandler" value="storage=file;timeout=20;url=~/TempImages/;" /> </appSettings> <httpHandlers> <add path="ChartImg.axd" verb="GET,POST,HEAD" type="System.Web.UI.DataVisualization.Charting.ChartHttpHandler, System.Web.DataVisualization, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" validate="false" /> </httpHandlers> <handlers> <remove name="ChartImageHandler"/> <add name="ChartImageHandler" preCondition="integratedMode" verb="GET,POST,HEAD" path="ChartImg.axd" type="System.Web.UI.DataVisualization.Charting.ChartHttpHandler, System.Web.DataVisualization, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" /> </handlers>
