Hide the row on grid

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
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
