HiddenField Value changes via client
<p>I'm using HiddenField in my Asp.net Page and store some value in it.
but user can changes it's value via firefox Firebug in client side and enter an invalid value in it.
so when user presses the submit button in the web page,invalid data will recieve in server side and invalid data will store in my database.
