copied!<p>Sorry, but you're doing it wrong. </p> <p>You do get bonus points for being extremely creative and ambitious in your solution. But you've taken the proverbial 5kg hammer down on a thumbtack. </p> <p>The correct solution in this situation is to use Storyboards nested in VSM States. It looks like you essentially have 2 States for your UI: One where some business logic value is true and another state for when it's false. Note that the aforementioned distinction is 100% technology independent. In any technology, whatever it is you're trying to achieve would be considered 2 states for your UI. </p> <p>In Silverlight/WPF, instead of hacking together something that mimics UI states, you could actually create VisualStateManager states. </p> <p><em>Technically</em> it would work in the following way:<br> 1. Your UserControl would have 1 VisualStateGroup that has 2 VisualStates (one for true and another for false).<br> 2. Those VSM states each represent 1 storyboard.<br> 3. That storyboard would change the template or any other properties you feel are appropriate.</p> <p>To learn the basics of VSM I strongly suggest you spend the next 30 minutes watching the following VSM videos: <a href="http://expression.microsoft.com/en-us/cc643423.aspx" rel="nofollow noreferrer">http://expression.microsoft.com/en-us/cc643423.aspx</a> (Under "How Do I?")<br> Seriously, these videos are phenomenally successful in explaining VSM. The one that most pertinent to your dilemma is "Add States to a Control" but I'll suggest you watch all of them. </p> <p>In WPF, you could use the VisualStateManager from the <a href="http://wpf.codeplex.com" rel="nofollow noreferrer">WPF Toolkit</a>. </p>
