Hi Sharmila ,
Thanks for reply.
I tried with smart form.
I created a smartform with only one text on smartform for just testing.
    i developed the BSP application .  when i press the butten "printpreview' on first page it should open PDF page with out put of smart form.
the code is as below... but it is not working...it is not giving any result.. just remains in first page.
