set watermark only when preview and print?

[progame]

I need show some watermark for trial verion. but i do not need save this in report content.
i can set it when call stireport.preview, but if user open designer and previw or print, how can i set it and remove it when save?
(sometimes user can set their watermark, then i keep it's setting and do not add my watermark.)

i find beginrender and endrender event, if i set it in beginrender and remove it in endrender, it seems ok.

but if user terminate render, what will happened? endrender event still fire?

[progame]

those two events never fired, why?

Hello.
