Wilhelm,

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.

<< It's possible now? or in a future release? >>

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.

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