referencing events after loadfromdatabase

rbuser

Dear all,
I need to reference the report.OnStartpage and the
report.DetailBandBeforePrint events of a report that has been loaded into a
component using Loadfromdatabase.

I explain it a bit more in the previous thread.

I am sorry to keep asking but I am really stuck and my customer is going mad
so I would really appreciate any help ASAP.

many thanks

John

Hi John,

Take a look at my reply to your previous post.

Dear Nico,
thanks for the extensive reply, but this does not really help me. It
does answer why I was losing my event handler references.

The reports in question are not created in Delphi, but by the end user, so I
do not know what the report template is actually called. Even if I did, it
is the users creating it, they have no idea about code and event handlers.

In the delphi form is an empty report component ppReport3.
The users create labels using the end-user reporting tool.
In the program is a grid displaying their reports from rbItem. They select
the report name when creating a print job.
When they click on print, the code uses LoadFrom Database to bring the
correct report template into ppReport3. It links the ppReport3 pipeline to
the appropriate data source. This all works great.
The last bit is this need to handle printing on label reels and sheets with
different numbers of labels per sheet, without wasting labels, and knowing
how many bandsperRecord. The code from the LabelsSkipPlusQuantity.zip looks
to answer all of these issues. It is just making it work with these user
generated templates.


I was wondering about some sort of code that said:

In the form Oncreate:

ppreport3.template.OnStartPageEvent:= ReportOnStartpage; (whatever the
REAL code is for this)

Then create a generic ReportOnstartpage event.

Then Do the same for ppReport3.template.detailbandbeforeprint.


Can this work?

Otherwise what is the best strategy?

kind regards

Use the Report.Template.OnLoadEndEvent to initialize any template properties
and event-handlers.

For example, you could put your proprosed code in there...

ppreport3.template.OnStartPageEvent:= ReportOnStartpage;
