asp.net control visibility using webmethod / jquery ajax
<p>As I know, if you want to call a web-method by jQuery it must be a static method, but a static method doesn't have access to page controls/members.</p>

<p>So how to set visibility to a control using webmethod or jQuery ajax? I want to pass the value (true-false) to the server. </p>

<p>I don't want to use CSS (<code>display-visibility</code>) or jQuery <code>(selector).hide();</code> because anyone can change it using firebug.</p>

<p>Is that possible?</p>

<p><em>I know there are tons of questions similar to mine but most of answers about using CSS and that's not what I want.</em></p>

<p>Thank you and sorry for my horrible English :)</p>
