Is there any way by which I can validate fora valid web
address...............

Well, you can always try to make an HttpWebRequest to the resource. But
this is no guarantee that the page exists as the server is free to return
whatever it wants. I have seen some sights that return a 404 custom page
but does not flag it with an actual 404 response code.

No, I just want an authentication saying this is could valid or invalid
web address, like we make a validation for valid or invalid email
address.

Maybe the regular expression validation control?

That makes no sense whatsoever. Peter gave you good advice. Checking the URL
format will not tell you whether or not a URL is valid. The following URLs
are all valid in format, but lead to absolutely nowhere:

http://xzqza.com/
http://www.google.com/nosuchpage.html
http://a.b.c.microsoft.com
