Can I hide the row on grid but still have its value (all cells) when I am serializing the data from that grid using Grid.serialize()?
You can use
grid.setRowHidden(id,true);
to hide row in grid ( method has known limitation, it may be problematic in case of srnd mode )
Technically instead of hidden row you can use global level userdata
