I have Main categories Sales and Return, in this categories I have sub-categories like snacks, tobacco products, vaporizer etc., into each of these sub-categories I have items. I want 3 level drilldown by binding chartview from backend. Please let me know which type of chartview will be suitable for this example and also can you please provide me a small working example covering this scenario.

Hello Jignesh,

Thank you for writing. 

Please refer to the following help article which demonstrates a sample example how to setup drill down chart: http://docs.telerik.com/devtools/winforms/chartview/features/drill-down

In addition, in our Demo application you can find a fully functional example: Demo application >> ChartView >> Drill-down example. You can find the Demo application in the installation folder: C:\Program Files (x86)\Telerik\UI for WinForms Q2 2016\Examples\QuickStart\Bin.

I hope this information helps. Should you have further questions I would be glad to help.

Regards,
Dess
