Re: [flexcoders] Manipulating data before it populates the DataGrid

[Harish Sivaramakrishnan]

I suggest you take a look at the fiterFunction and labelFunction methods on the datagrid. Since the datagrid dataprovider is an arraycollection, you can apply all utilities that are available on the arraycollection class to manipulate what you display in the datagrid finally

            If you're using an ArrayCollection to populate your grid you could 
always
edit/adjust or otherwise manipulate the data in your event handler. For
instance, if you're using Web services, you can loop the data coming 
from
the server and manipulate it as you add it into your ArrayCollection.
Or, as suggested you can just use formatters to change *only* the 
display
of specific columns w/o affecting the actual data.
