Chart Webparts Creation using Visual Studio in SharePoint 2010

http://social.technet.microsoft.com/wiki/contents/articles/17614.adding-charts-to-standard-webparts-and-visual-webparts.aspx


Note: Modified below things as per environment

1)  Add "ChartImageHandler" in system.WebServer handlers tag inside:

So the simple solution that worked for me was just to remove the following entry from web.config <system.web> section:

<httpHandlers>

<add path="ChartImg.axd" verb="GET,HEAD,POST" type="System.Web.UI.DataVisualization.Charting.ChartHttpHandler,

System.Web.DataVisualization, Version=4.0.0.0, Culture=neutral,PublicKeyToken=31bf3856ad364e35"

validate="false"/>

</httpHandlers>

Also make sure that <system.webServer> section has the following:

<handlers>

<remove name="ChartImageHandler" />

<add name="ChartImageHandler" preCondition="integratedMode" verb="GET,HEAD,POST"

path="ChartImg.axd" type="System.Web.UI.DataVisualization.Charting.ChartHttpHandler,

System.Web.DataVisualization, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />

</handlers>
