Swivel Behavior

For my application I'm using a trigger button with the State management going on behind it as you specified in your tutorial. My desire is to have the text change as the button changes state. I am able to set the Checked and Unchecked states and I specified changing the Content from View Alpha to View Beta. Unfortunately this didn't quite work. The text remains as View Alpha regardless of how many times I click the button. Any suggestions?

I'm not sure how to use this. I'm using Blend 3 and created a very simple SL3 app. I created 2 empty wrap panels and made one the Front and the other the Back. I used Blend to create a Trigger event so that when I hit tab it attempts to start.

But I keep getting an InvalidOperationException at this line:

animation.KeyFrames.Add(new EasingDoubleKeyFrame { KeyTime = new TimeSpan(rd.AnimationDuration.TimeSpan.Ticks / 2), Value = rd.MidDegrees });

Make sure you set the Duration to a valid time, too. Such as 00:00:01 (which is 1 second).
