After checking with the developer, it’s not possible to create empty groups (without any child rows). The only one to “workaround” this problem would be to add invisible row to a group.
However, it is possible:
2. To catch expand/collapse event s of the custom group
Group group = new Group( “Column1” );
group.CollapsedChanged += new EventHandler( group_CollapsedChanged );
void group_CollapsedChanged( object sender, EventArgs e )
