title: WPF MVVM - Info bar sliding animation
body: <p>I'm very new to the animation / graphical side of WPF and struggling.</p>
  
  <p>I have a user control which consists of 4 text boxes and a button.</p>
  
  <p>I am looking to have a bar slide down from the top of the control and display datatemplates</p>
  
  <p>I don't have a any code or examples to add which I have written so far really as my angles of attack have been so varied. I am under the understanding that I want a Storyboard for Expand and Collapse but not sure how to animate this from a MVVM perspective.  </p>
  
  <p>Would it be best to use a DockPanel or Stackpanel with a content control in maybe? Or something totally different?</p>
  
  <p>Any relevant animation or mvvm/animation tutorials would be greatly appreciated.</p>
  
  <p>Edit - Added "rough" concept image.  </p>
