Asp.Net: Charting Control (Error ChartImg.axd)

After installing and playing with the Asp.Net Charting control I decided to use it for a customer. When integrating the control to the project I got the following error

"Error executing child request for ChartImg.axd"

This error occurred because I did not update my web.config file. You have to add the following appSettingkey, httpHandler and handler.

[code:xml]

<appSettings>
    <add key="ChartImageHandler" value="storage=file;timeout=20;dir=c:TempImageFilesDit;" />
</appSettings>
<httpHandlers>
    <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" />
</httpHandlers>

<handlers>
    <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>

[/code]
