Hi there,
after setting up some parameters (in runtime) and loading a template, the
parameters are not available in the template just loaded.
Is there a way to avoid this? (Except setting the params after loading the
template...)
Thx in advancen,
greets ben

When you load a template, all current parameters and properties of the
report are replaced with the items saved with the template. You can use the
template events to set any parameters of a report after it has loaded.
----------------------------------------------
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;
