short string representing Viewstate Visible even if view state on each and every control is disabled
<p>I disabled the viewstate on page and each control within it. But I still see short string representing the viewstate in the page source.</p>

<p>I created a page with two controls, one a checkbox and other a texbox. I completely disabled the viewstate for both the controls and the page. But I still see a div rendered which contains the viewstate in the hidden variable: </p>

<pre><code>&lt;div class="aspNetHidden"&gt; &lt;input id="__VIEWSTATE" type="hidden" 
    value="/wEPDwUKMTcwNTQzMjY4MWQYAQUeX19Db250cm9sc1JlcXVpcmVQb3N0QmFja0tleV9fFgEFG‌​
    2N0bDAwJE1haW5Db250ZW50JGNoYm94VGVzdPRq7jJUwzyCcKYfAFB/seRcAvziSp3bKL23H9U7O9sU" 
    name="__VIEWSTATE"&gt; &lt;/div&gt;
</code></pre>

<p>Can anyone help in understanding this behaviour of asp.net</p>
