title: How can I make the changes of a transformation stick?
body: <p>So I have a <code>FrameworkElement</code> to which I apply a template that has a thumb. I calculate the angle and then I set the <code>RenderTransfrom</code> property equal to a <code>RotationTranform</code>. Once I do the rotation and want to do another rotation, the changes don't stick, that it the element returns to its initial position. How can I make the changes stick after a transformation has been applied. Any help would be appreciated. Thank you.</p>
  
  <p>Do transformations affect the actual element or are they only a rendering thing? Also do they affect the bounding box of the element? I tried a layout transformation and still the same result.</p>
