It is server side control not the html file input control

There is no such thing as a server side control, on the client. The 'server side control' is rendered as a html control, that's all it could ever be. whatever happens, on postback, your control will contain the bytes of your file and it's name. viewstate is for persisting values between postbacks, a file is assigned, sent on that postback and forgotten.
