I want to know how to make a site in the different language
i.e language other than english without prompting to download
the font file in client windows/font folder.

Do some web searches for ASP.NET and Globalization. This is an advanced topic, and it's hard to cover it here in this forum.

If you don't want users to download a font, you'll have to put all your text into images. This can make your site slow for people with a dial-up connection.
