Basic WPF question: How to add a custom property trigger?

I am using Expresion Blend 3 and created a new user control in my project. I want a storyboard to run if a custom property of that user control is triggered like with the ones shown here in the list..

I learnt you need a dependency property, but my understanding there is limited. Here's the basic code I set up with property "IsAwesome" as an example..

Partial Public Class simpleControl
    Public Sub New()
        MyBase.New()
        Me.InitializeComponent()
    End Sub

    Public Shared ReadOnly IsAwesomeProperty As DependencyProperty = _
        DependencyProperty.Register("IsAwesome", GetType(Boolean), GetType(simpleControl))

    Public Property IsAwesome() As Boolean
        Get
            Return DirectCast(Me.GetValue(IsAwesomeProperty), Boolean)
        End Get
        Set(ByVal value As Boolean)
            Me.SetValue(IsAwesomeProperty, value)
        End Set
    End Property
End Class

Howev开发者_运维百科er, my property doesn't show in that list. What am I missing? Or is my entire approach wrong? Any help or advice would be appreciated!

Cheers

I created a new Wpf project. Added a new UserControl (UserControl1) with a custom dependency property called Foo.

Then I opened Blend and added an instance of UserControl1 to Window1. I right clicked on UserControl1 and said EditTemplate | Edit a Copy.

This created a copy of my user control template in the Window.Resources. From within this new template I went up to the Triggers panel and clicked the button to add a new property trigger.

Right away Blend defaulted to selecting my property in the "Activated When" section.
