title: asp.net requiredfieldvalidator dont work when visible=false
body: <p>I have some requiredFileldvalidators in my asp.net site that i want to set invisible until needed. But when i set them to visible=false they do not fire. They do work if they are set visible=true.</p>
  
  <p>Is this the correct behavior of this control or is this wrong. I want them invisible due to styling issues when visible.</p>
