jQuery Grid Plugin - jqGrid

Hi everyone?

I am using client array. I need to hide certain rows in the grid depending on some value of one of the columns or a row index.  Is this possible with jqGrid ? I don't see any methods for hiding rows.

 I know there is .delRowData() but I need to just hide the row, not delete it from the grid.I will post all data include the hiding data to server.

Tony offer two methond in other topic:

1.jQuery("#myid").hide()

2.("#row_with_row_id","#mygrid").css({display:"none"})

but it seems don't work. Do I misunderstand rowid? I use code just like "jQuery("#1").hide()" .

Regards
