That is how I do it mostly. My models are usually xml, and I put a
dtamodified=true attribute on any leaf node that changes, and on each
parent up to the root.
On save, I use e4x to list the nodes with that attribute, and build an
update structure to send to the server.
Alternatives might be storing the indexes of changed items, or storing a
reference to the changed item itself in an array.

(and which don't) ?
How about to have a flag field in your data?
every time a row is modified set the flag to true for that row. Then filter
data on that flag and send back modified rows only.

Hi, People
I have a datagrid where user can modify a few rows out of 200 - 500 then
click save. I only want to hit the database with the changed rows. Is there
a technique whereby I can identify the dirty rows, pluck them out, and
ship only them off to the database, without going thru and comparing column
by column, row by row?
Thanks,
Libby
