Silverlight Triggers in a Button Template?

Does anyone have a functioning example of how to use triggers in a Silverlight Button Template using the Microsoft.Expression.Interactivity dlls?

I want to respond to the click event in a Button's template d开发者_StackOverflow社区efined in a style, by triggering an animation.

You want to use an EventTrigger that fires a GoToStateAction

<Button x:Name="button" Height="53" HorizontalAlignment="Left" Margin="173,124,0,0" VerticalAlignment="Top" Width="147" Content="Button">
    <i:Interaction.Triggers>
        <i:EventTrigger EventName="Click">
            <ic:GoToStateAction TargetName="checkBox" StateName="Checked"/>
        </i:EventTrigger>
    </i:Interaction.Triggers>
</Button>
<CheckBox x:Name="checkBox" Height="24" HorizontalAlignment="Left" Margin="173,206,0,0" VerticalAlignment="Top" Width="147" Content="CheckBox"/>

To do this in Blend you would drag a GoToStateAction onto the button and then set the TargetName property to the target UIElement and the StateName property to the desired state.

You can always use the VisualStateManager and change to the "Click" state by handling the click event of a Button.

void myButton_Click(object sender, RoutedEventArgs)
{
     VisualStateManager.GoToState(this, "Click", true);
}

You will also need to define a style and state in the XAML code.

<Style x:Key="ButtonStyle" TargetType="Button">       
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="Button">
                        <VisualStateManager.VisualStateGroups>
                            <VisualStateGroup x:Name="StateGroup">
                               <VisualState x:Name="ActiveLink">
                                    <Storyboard>
                                        //animations go here
                              ...

Also, remember that Button objects have a bunch of predefine states like Disabled, Pressed (Click?), MouseOver, and Normal.

looks like it wasn't possible at that time.
