First of all you need to convert contents of gridview to Pdf. There is an third party dll:- iTextSharp dll which will help us to convert gridview contents to pdf.
1. Just Download iTextsharp lib. from http://sourceforge.net/projects/itextsharp/
2. Add 1 form in your project named as "pdf" then copy following design & Code behind code & replace it in your code.
Currently we have taken 1 gridview & button on form.
You can bind your data to gridview as you required. I have just created dataset manually & assign it to gridview
Design Form

Above code snippet will help you to generate pdf.
Happy Coding !!
