I am trying to create a toggle button that will display a different image depending on if it is checked on unchecked. From what I am reading this should work, but it does not.

<Style Selector="ToggleButton.SoundOnOffButton">
    <Setter Property="HorizontalAlignment" Value="Center"/>
    <Setter Property="VerticalContentAlignment" Value="Center"/>
    <Setter Property="Margin" Value="10"/>
    <Setter Property="BorderBrush" Value="Transparent"/>
    <Setter Property="HorizontalContentAlignment" Value="Stretch"/>
    <Setter Property="VerticalContentAlignment" Value="Stretch"/>
    <Style.Resources>
        <Image x:Key="SoundOnImage" Source="/Assets/Sound/icon_sound_alice.bmp" />
        <Image x:Key="SoundOffImage" Source="/Assets/Sound/icon_sound_off_alice.bmp" />
    </Style.Resources>
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate>
                <Image x:Name="ButtonImage" Source="/Assets/Sound/icon_sound_off_alice.bmp" Classes="SetupButtonImage"/>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

<Style Selector="ToggleButton.SoundOnOffButton:checked /template/ Image#ButtonImage">
    <Setter Property="Source" Value="/Assets/Sound/icon_sound_alice.bmp"/>
</Style>

Here is how it is referenced

<ToggleButton Grid.Row="4" Grid.Column="3"
        Classes="SoundOnOffButton">
</ToggleButton>
