PDF Creation help required

Thanks Mahesh 
It is really helpful

In that case, you can use PrintPreviewDialog class. Here are couple of articles.

Thanks Mahesh
The reason i want to show preview because user can define there own alignment of a image before creating i.e pattern of PDF generation will be decided by end user rather than forcing fixed pattern

how can i show it in a window? i mean what kind of control should i use?

Even for preview, you will have to generate the PDF. I guess, you can create a Window where you can generate and show the PDF. Have Close button on it.
