I have a RadTreeList and my data consists of 3 levels/hierarchy. I want to export it to excel with the grouping functionality. Unfortunately, Radtreelist doesn't have this functionality. Has anyone done something similar with RadSpreadProcessing?
I've read the documentation https://docs.telerik.com/devtools/document-processing/libraries/radspreadprocessing/features/grouping but haven't had any luck in implementing it.
