How to take screen shot of full page in C#.net

Hi,

I have a web-page, height and width of page exceed the screen size of my display device. I want to take screen shot or print it in pdf of that web-page with that hidden portion too using C#.net.

I don't want to call print dialog box. My requirement is that a User will click a button called "Print", then system should automatically do this above mentioned work.

Please suggest me to proceed.


Thanks in Advance.
