Hidden controls are simply not shown on the page, but their labels and values are sent to the server when the form is submitted. So you just use them as if they were not hidden: 

<input name="foo" type="hidden" />
<input name="bar" type="text" />

They are both treated the same when the server receives their values: http://server.com/path/to/form?foo=1&bar=1
