I am trying to get querystring value using post method, but value is not retrieved. Please Help

What error did you get ? Maybe a null when id is not exist ? — Aristos

It's not a test question. Sometimes value is not passed and sometimes querystring is appended to the url. — Mohan Sharma

Use Request.Form["var"]
