title: Dynamically created Silverlight controls not visible
body: <p>I am dynamically adding custom controls in Silverlight 2 but they are not visible. However, on examining the visual tree in Silverlight Spy I note that their visibility property is Visible and toggling it to Collapsed and back to Visible causes the controls to become visible.</p>
  
  <p>What might I be doing wrong? Any ideas on what I should look for to resolve this?</p>
