Fill a TppRichText at runtime

rbuser

Hi !

I'm new to ReportBuilder (use Demo v7.02) and I want to know wich event to
use to fill my
TppRichText (on a TppDetailBand) at runtime. If I use the BeforePrint event
of the TppDetailBand or the OnPrint of the TppRichText, everything is OK on
the preview form (called with the Print method of TppReport), but when I
print after the preview, the content of the TppRichText is duplicated (I
think the events are fired twice).

Sure I can use the Clear method of my TppRichText at the beggining of the
event, but it's just a "patch" wich I don't like to use...

So, wich event is fired once (even if I print after a preview) ?


By the way, ReportBuilder is soooo better than QuickReport !

Anyone can help me ?
Thanks !

Hi !

I forgot:
The TppRichText is filled for each records of the database...

Thanks !?

Hi,

Thanks for evaluating ReportBuilder. The BeforePrint and OnPrint events
will fire more than once during report generation. Try clearing the
TppRichText.RichText property before you add text to it from your database.
This way you will not be printing duplicate information every time the event
fires.

Hi !

(Your support is also better that QuickReport.)

I know, but I want to know how to avoid this. If I use a long treatement to
fill my TppRichText into TppDetailBand.BeforePrint event and if I use a
TppRichText.Clear at the beggining of the event everything is OK in the
preview ant in the printed copy, but the long treatment is duplicated and
the performance is affected...

The text into the TppRichText changes for each records of the database. I
want to know if theres an event fired only once per record even when I print
after a preview... When I must fill my TppRichText ??

Thanks a lot !

Hello,

There is not an event available that will only fire once per record. You
can still use the DetailBand.BeforePrint event and instead of clearing the
RichText control, you could check to see if the information you want to
insert is the same as the information already inside the TppRichText. Then
you can only change the RichText component when the information is different
without loosing any performance.

Hi again !

Thanks for your help ! I finally got a solution. I use the
TppRichText.OnPrint event to fill my TppRichText for each records of the
database. I'm also forced to put a TppRichText.Clear at the beggining of the
event. I don't like it but I think it's the only solution...

Nico Cizik, as a Digital Metaphors employee, do you find that my solution is
odd ? Just want the advice of a ReportBuilder expert...

Thanks !

That's how I would do it .
