Hello, Bert,

Thank you for bringing this to our attention. We will do our best to introduce similar experience like in RadGridView.

Currently, the possible solution that I can suggest is to handle the RowExpanded event and set the current cell programmatically:  

       private void RadVirtualGrid1_RowExpanded(object sender, VirtualGridRowExpandedEventArgs e)
       {
           this.radVirtualGrid1.VirtualGridElement.CurrentCell = new VirtualGridCellInfo(e.RowIndex , this.radVirtualGrid1.CurrentCell.ColumnIndex , this.radVirtualGrid1.MasterViewInfo);
       }

I hope this will help.
