Custom Prievew

rbuser

Is it possible to have multiple instances of a custom preview on screen if
its not modal .. SO they can prievew two documents at the same time in two
windows ?

Hi,

Yes, but you will need to create or place multiple TppReport objects on your
form in order to view more than one report at the same time.

I am creating them dynamically using Loadfromdatabase Then Print .. The
custom preview window is displayed automatically .. How do i direct it to
instance a new preview window ?

Hi Adrian,

So you would need to dynamically create the TppReport objects and load the
templates from database based on how many reports you would like to view at
the same time. If the custom preview is properly registered there it will
automatically be displayed. Example... (this is rough psuedo code).

var
lReport: TppReport;
lList: TList;
liIndex: Integer;
begin

lList := TList.Create;

try
for (liIndex := 0 to NumberOfReports - 1) do
begin
lReport := TppReport.Create(nil);
lReport.Template.DataBaseSettings....
lReport.Template.LoadFromDatabase;
lReport.ModalPreview := False;
lReport.Print;

lList.Add(lReport);
end;

finally
for (liIndex := lList.Count -1 down to 0) do
lList[liIndex].Free;
end;
end;

yes had already spotted it foloowing your note . was assigning them to teh
same PPreport (sorry)

While your at it .. I have added an email buttin to the Preview Page . i
need to run ExportToPdf(PPreport1.. code ..
what is the paramater from the Customeviewer that gets me back to the report

What i need is something like ExportToPDF(PPViewer1.Report,Filename) ..
But Report points to a PPProducer not a PPreport

Hi Adrian,

TppProducer is the ancestor of the TppReport object. If you typecast the
Report property as a TppReport object, you will have full access to the
report.
