title: How to change Text property of TextBlock in between animations?
body: <p>My WPF app has animation along these lines:</p>
  
  <p>a. Rotate a TextBlock from 000 to 090.
  <br>b. Update the Text property of the TextBlock to a new value
  <br>c. Continue rotating the TextBlock from 090 to 180.</p>
  
  <p>I am able to achieve steps a and c, by adding two DoubleAnimations to the Children of a StoryBoard.  Is there a way to trap the end of the first animation to do some work?</p>
  
  <p>Thanks.</p>
