DBBrowse question

[g.s.rogers]

Does DBBrowse reflect relationships set between the underlying dataset and
another dataset, or does one have to always scope the underlying dataset in
the OnChange event of the DBBrowse object?
TIA,
Gary

Gary,
You can include a reference to another dataset using the event
TBrwColumn:OnGetData.

I appreciate the information, but I probably wasn't clear in my question.
I have a form that has datacontrols for one dataset (the main table) and
shows several DBBrowse controls for related child records. Although it is
not an accounting form, it would be similar to a form that showed the master
record for an invoice and several browse controls for invoice detail items.
I can successfully establish a scope for the child datasets in the OnCreate
event of those child datasets. I tried simply relating the child datasets to
the parent dataset in the OnCreate event of the child dataset, but the
DBBrowse controls did not display properly -- that is, they showed all
records in the child dataset, not just those that matched the SetRelation()
parameters. I could not use the debugger to verify that the SetRelation()
was in effect. So, I went back to scoping the child datasets, which works
for me except for one thing. When I perform an AddNew() for a new master
record, I would like the other child controls on the form to clear. Instead,
they show the information for the last displayed master record (of course).
In my Clipper app, I was used to setting relationships between tables. With
a relationship set, I could be assured that if the master record changed to
eof()+1 (for adding a new record), then there would be no related child
records and the user interface would reflect that -- all the child browses
would show no records. I'm trying to get the same effect in Xailer, but
don't know quite how to go about doing it.
I guess on an AddNew() of a master record, I could re-scope the child
controls on the form with some non-existent value and repaint them. Would
that be a good way?
TIA,
Gary

Gary,
Gary,
On AddNew() methods the physicall append is not done yet, BTW you can do the
append your self and do an Edit() instead.
I suggest you use a string variable instead of a field value for the scope
and change that string to whatever non existing value when caling to
AddNew().

Thanks, Ignacio. I've created a function I named ClearControls, which scopes
the datasets with a non-existent string, effectively clearing out the linked
data controls. I have another function, ResetControls, that scopes them
again using valid parameters, effectively refreshing the linked controls
with data. This is working very well.
I have to say I like Xailer very much. With a little work and your help, I
seem to be able to get past every obstacle!
