We are having problems with RadCharts, we are using the latest telerik dll,
An error occurred during the processing of . Telerik.Charting.ChartSeriesCollection must have items of type
'Telerik.Charting.ChartSeries'. 'ChartSeries' is of type 'System.Web.UI.HtmlControls.HtmlGenericControl'.
After some investigation we added the following line in the web.config line:
add verb="*" path="ChartImage.axd" type="Telerik.Web.UI.ChartHttpHandler, Telerik.Web.UI, Version=2008.3.1314.35, Culture=neutral, PublicKeyToken=121fae78165ba3d4" validate="false" />
After this line was added sharepoint displayed the following error:
"An unexpected error has occurred"
Could any one help on this issue?
