Hello,Sorry you could not find the ChartData class. The ASP.Net samples use a Web site project that requires all custom classes to be located under the App_Code directory. The file you are looking for is a typed dataset and its located under App_Code\CS\WebCharts\ChartData.cs. Let us know if you need any other assistance.
