Subject Tabs in forms...
Author Dany Marmur

This is not about a specific case but more about design. For best
performance (and I'm thinking about bandwidth) what way aould you go about
to implement tab pages in a form? The form always has one "MainQuery" and
fields from that are shown i all tabs. The LookupLinked fields and
Masterlinked grids are littering the tabs. All is connected to one

1. Split up MainQuery into one for each tab.

This strikes me as messy. One would have to make sure te correct record is
shown when the user switches tab. One would have to prepare three queries
instead of one that might contain the same fields. There might be problems
with default vaslues of fields not present in som Query/Tab when posting an
Insert from a specific tab. It might be tricky to handle Inserts if the user
wants to wsitch tabs while inserting. Logic migt be needed to post in a
specific order from the tabs.

2. Turnig off controls and links in tabs that don't show.

I'd like to persue this line of action. How do I do this - I don't know! I
would like to tell the controls in one tab to simply not receive anything in
th style of DataChange, DataUpdate, StateChange and so on events. This would
make if so that a gid in tab 2 won't have to update when working in tab one.
It would mean some event would have to be sent to all the controls in an tab
that is opening but that should be fast since the data is already there
(except for masterlinked queries). Is it feasible to also switch off the
masterlinked and/or Lookuplinked Queries themselves? How does one go about?
Should I "disconnect" or disable the Datasources for the specific tab?

It would be nice if an open masterlinked Query in which the user has done
changes would _not_ be closed when switching tabs so that the user can come
back and continue editing util the whole thing is committet.

3. ??? More?

Thanks a lot,
