Do you have any sample project using ultrawebchart(column) and chart can drill down? I found the sample code in help document but only part of the code I need the project that I can see all the code.
Thank you for contacting Infragistics developer support. I am attaching a working sample based on our online help tutorial - http://help.infragistics.com/NetAdvantage/ASPNET/2011.2/CLR4.0/?page=Chart_WebChart_Set_Up_Drilldown_Charts.html . Please take a look at it and modify your code based on it. Sample was tested with IE 9
