Hello, Valerio, 

Thank you for reporting this issue. I have also updated your Telerik points.

Currently, the possible solution that I can suggest is to force refreshing the grid in the RowExpanded event as follows:

private void radVirtualGrid1_RowExpanded(object sender, Telerik.WinControls.UI.VirtualGridRowExpandedEventArgs e)
      this.radVirtualGrid1.Width += 1;

I hope this information helps. If you need any further assistance please don't hesitate to contact me.
