ADD. RadVirtualGrid - add grouping support
I miss grouping functionality in VirtualGrid. In my opinion, the following process would be conceivable:
1. user interaction triggers an event - e. g. GroupChanged (similar to FilterChanged).
2. This event determines all available groups and returns them to the VirtualGrid. 
3. if the user expand a group > a second event is fired - and returns all matching data rows.

Hello, Jan,

Thank you for writing.  

Currently, the grouping scenario can be handled by using a hierarchy. You can create a UserControl that will introduce the user the desired UI for grouping by certain columns. Then, you can contruct the different levels where at the top level you will fill the groups and when expanding a group you will populate with the relevant records. The following help article demonstrates how to build different levels in RadVirtualGrid: https://docs.telerik.com/devtools/winforms/virtualgrid/hierarchical-virtual-grid/hierarchical-data 

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