I m trying to prepare a document viewer in asp.net 4.0. My requirement for this viewer is that all users coming to my website will be able to view every document. uploaded by him on my web-server.

I want to know any third party free application/service/user-control i can use in my website and open all my documents (.doc, .docx, .xls, .xlsx, .ppt, .pptx, .pdf, .jpg, .gif, and other image formats.)

I found Adeptol Viewer, TX TextControl. but this are very costly, ranging $5000 and above. can i get any cheap control..

EDIT : Also i want to know, is it possible to create such custom control in .NET and use it for our future use. If possible please guide me how i can achieve this. It is fine I can use Client Scripting like jQuery. for this

Awaiting for the reply from any technical experts who is willing to help/ support my question.
