Groups not working properly

rbuser

I'm working on a report where I have 3 different groups that are shown
depending on user selections, only one group at a time is visible. The
problem is that the group breaks are not corresponding to the breakname
variable value. I'm setting all groupHeader bands to 'Visible := False' and
all groups 'NewPage := False' in design mode and then set them to 'True' for
the group the user choose.
Trying to find a work-around using manually breaks (BreakType btCustom)
failed too since the groups are still breaking in the same way as with
BreakType btDataField.

Any ideas anybody?

I'm using Delphi 5 with all updates,
ReportBuilder 6.03 standard ,
Windows Y2K


Thanks,
Lars.

How are you setting up breaking conditions for the groups? Please see the
demo below for an example of breaking group on a variable value.

Thanks for the demo Alexander, I will check it out.

However, I would prefer to have the groups break as expected when the value
of the connected database field change. I'm still clueless about the way
these groups are breaking, I've checked the tables several times without
finding anything that should trigger a break.

Thanks,
Lars.

Groups that are set to break on a data field break every time that data in
the field changes. How is the data in the field value of the table on which
you have the group set organized? One possibility is that the data might
need to be sorted in the query, so as to group it by identical values, to
avoid multiple group breaks among unsorted data.

Well, thats pretty obvious that the query should be sorted on the same field
as the field thats trigger the group breaks, and it is.
Even when I'm generating a query where the sort field value is the same for
the whole result set these group breaks still happens (and in this case
there is just one group)

Any more ideas?


Thanks,

You have to code the OnGetText event handler of the variable and not the
OnCalc event to set the group break value.

Ok, but thats still handling the breaks manually, isn't it? If thats the
only possibility I'll go that way, but I'm not really happy with it.

Thanks

Can you send us a simple working example project in which the groups do not
break correctly- we would like to fix it if it is a problem. Please send it
to support@digital-metaphors.com

When I deleted all groups exept one and, instead of setting visible/not
visible to activate different groups, manually changed the break conditions
for the group to whatever recordfield that group should break on, it worked!
Seem to me that there are some bugs in ReportBuilder regarding groups.

Thanks,
Lars.

Ok, will do.
