I have a report along with sub reports and I need to open the report on a single button click. The Crystal Report is perfect while running itself, but when I do that through webforms, it’s not working well.

I have a report along with sub reports and I need to open the report on a single button click. The crystal report is perfect while running it self but when I do that through webforms it’s not working well. The concept is like printing id cards for n no .of students/employees where details will be in main report and photo will be in sub report but the problem is the photo of one person is getting duplicated in all the pages. The parameter fields are linked perfectly in the stand alone report and that too working well.
