i want to load some data to grid view (which is not existing in the database currently)
and do some chages (putting tax rates etc) and caluculate totals and after all changes done
to update them on the database,
where can i keep those data temporaly ? and do the manupulation and then update datatbase finally
it seems i can't use row updating event on grid view(because i don't want to subit it to database untill
i update each and every row manualy)
what do you suggest ?
