I'm trying to get a Drilldown working on WinForms with VB. I've customised it as needed, however I'm getting an error when trying to DrillDown as below:
Unable to cash object of type 'System.Data.DataRowView' to type "TestApp.DrillDownDataInfo'
I've looked at the guide here - http://docs.telerik.com/devtools/winforms/chartview/features/drill-down
However I do not seem to have a access to the sample files:
So I haven't been able to look at it properly. Any help on this would be much appreciated or even a working demo in VB?
Thanks in advance.
