Load Template File the load image in ppImage ...

rbuser

Hi All,

I am have a bit of a delimer.

I have have a ppReport component on my form which i load the template into
on the fly.

Once the template has been loaded from file, i the want to change 3 images
on the form before i call the print so the images are updated in the report
before i preview to the screen.

I have tried a few different ways with no success, has anyone had any luck.

Thanks in advance.

Hi Trevor,

I would recommend using the Template.OnLoadEnd event to alter a report after
a template has been loaded. Take a look at the following article.

----------------------------------------------
Tech Tip: Using Template Events
----------------------------------------------

The Report.Template object has several events that can be used for
customizing what happens when a report is loaded or saved:

- OnLoadStart
- OnLoadEnd
- OnNew
- OnSaveStart
- OnSaveEnd


The OnLoadEnd and OnNew events are often used to perform actions related to
report and data initialization.

The OnSaveEnd event is often used to save additional descriptive ("meta")
data to the database each time the report is saved.

Example:

The Report.Template events are public and therefore must be assigned at
run-time.


1. In the private section of your form declaration you can declare an
event-handler method:

TForm = class(TForm)
private
procedure myTemplateOnLoadEndEvent(Sender: TObject);

public

end;


2. In the Form.OnCreate event, you can assign the event-handler to the
event:

procedure TForm1.FormCreate(Sender: TObject);
begin

ppReport1.Template.OnLoadEnd := myTemplateOnLoadEndEvent;

end;


3. Implement the event-handler method:

procedure TForm1.myTemplateOnLoadEndEvent(Sender: TObject);
begin

{add code here to initial the report or data, etc. }
ppReport1.PrinterSetup.MarginTop := 0.5;

end;
