actionscript 3 - how to hide a row without deleting item from dataprovidor in DataGrid...AS3,Flex? -

how can hide row @ specific index of datagrid in as3 ?

if dataprovider of datagrid arraycollection can specify filterfunction property it, that

dataprovider.filterfunction =     function (item:object):boolean{         if (dataprovider.getitemindex(item)==indexofrowyouwanttohide){             return false;         }         return true;     }; 

the item still in arraycollection made invisible filter. not efficient solution works. need call

dataprovider.refresh(); 

to apply filter.

update: access raw, unfiltered data of arraycollection should use list property, if hid item @ index 0 , still want able access this:

dataprovider.list.getitemat(0);
