PieSeries Drill Down Not Possible?

[Daniel]

I can easily create a RadChartView drill down using the BarSeries ( following the WinForm demo provided by Telerik ) but cannot, after days of troubleshooting, create a PieSeries drill down using nearly the same project/logic as the BarSeries.

If possible, can someone point me to a simple proof of concept where a user can start at a PieChart, drill down to another PieChart and follow the breadcrumbs back to the home PieChart?

It seems that when adding a new View to my RadChartView1 using .AddNew() it always adds a Cartesian chart ( even though RadChartView AreaType is set to Pie ), maybe that is why it works fine with BarSeries and not PieSeries? I see when the DrillEvent fires, the DrillEventArgs e.View is always a Cartesian ChartView which of course doesn't work so well when I attempt to do e.View.Series.Add(series) where 'series' is a PieSeries ( the new PieChart I want to drill down into ). 

Thanks for any help, resorting to the forums as I've banged my head on this matter for days.

Hello Daniel,

Thank you for writing.

We have an issue with the drill-down functionality in RadChartView logged here: FIX. RadChartView - series cannot be drawn when the areas on different levels have type. I have added a vote for the item on your behalf, additionally, you can subscribe to it and be updated with its status changes.

I have prepared a sample project demonstrating how a similar behavior can be achieved using the SelectionController. Please find it attached and let me know if it can fit your actual setup. I am also sending you a short video showing the result on my end.

I hope this helps. Should you have further questions please do not hesitate to write back.
