How to Make SelectedItem be a Dynamic Variable?

Question

Hi,
My client wanted me to create something that allows certain
DataGrid to display to allow users to edit and update the database
records. The only dilemma I am having here is how to actually
create something from Flex's end to allow users update several rows
of the database at once. Since everything in my HTTPService is in
DataGrid, how can I get Flex to recognize each of the updated
variables while I update the database? I tried using dg.
.id in my code, but I kept getting errors that say it is not
defined. Is there some way where I can make selectedItem be a
dynamic variable?
Thanks in advance.

This is the current code I have:
Attach Code:
<mx:HTTPService id="save_scenario" method="POST" url="
http://localhost/save_scenario.php"
useProxy="false">
<mx:request xmlns="">
<scenario_name>{scenario_name}</scenario_name>
<id_no>{dg.selectedItem.id}</id_no>
<region_name>{dg.selectedItem.region_name}</region_name>
<population>{dg.selectedItem.population}</population>
<market>{dg.selectedItem.market}</market>
</mx:request>
</mx:HTTPService>

Add like an updated property to each item in the collection.
Then set it
when the user has changed something. Then filter the
collection to items
that have been updated and send them to the server.
