Sorry about that, I missed the mark with my answer. What you're needing, at
the very least, is an OnCalcFields type of situation where you can do
lookups, etc. as the row changes. I was thinking that the OnRowChanged
event would provide that, but no, you can't modify the active row from
within that event. Or, I should say, you *can*, but you get into a mess
really quick in terms of recursion.

In the future, it's not supported now.

why Delphi has DataSource, >>
The TDataSource component is unnecessary, which is why we didn't add
something like it to EWB. It's an unncessary layer.
<< DBConnectionUnit doesn't know nothing about BussinessLogicClassUnit,

simple to maintain. It's possible with EWB this setup? I don't see

No, you can't do that type of setup with EWB.
