I'm using Telerik UI for WPF, R2 2018 SP1
GanttView has TreeColumnDefinition to display items that have parent/child relationship nicely, without extra header
Is there a way to use TreeColumnDefinition in RadGridView, since it's support sort, filter, context menu (which GanttView doesn't have).
I've browse over Seft-Referenced Hierarchical example, but all of them add an extra header to child item, and not support multiple hierarchical
Thanks in advanced
