I'm making my own ControlTemplate for a standard Button in WPF. I want to change the background of my button when the user hovers over the button with the mouse, but also when the user presses the button (to yet another color). This seems like a common behavior, but I can't get it to work.

My template consists of a Border with an Image inside. It is the background color (a gradient really) of the Border that I want to animate. I have triggers in my template that activates animations (storyboards).

The MouseOver/Out works just fine. My problem occurs when I press the button. The Press animation runs as it should, and so does the Release animation. But after this the MouseOut will never run. The button gets stuck in the MouseOver state.

What am I doing wrong?

<ControlTemplate TargetType="{x:Type Button}">
    <ControlTemplate.Resources>
        <Storyboard x:Key="MouseOverAnimation">
            <ColorAnimation Storyboard.TargetName="ButtonBorderGradientStop1" Storyboard.TargetProperty="Color" To="#ffefefff" Duration="0:0:0.2" />
            <ColorAnimation Storyboard.TargetName="ButtonBorderGradientStop2" Storyboard.TargetProperty="Color" To="#ffc7c7ff" Duration="0:0:0.2" />
        </Storyboard>
        <Storyboard x:Key="MouseOutAnimation">
            <ColorAnimation Storyboard.TargetName="ButtonBorderGradientStop1" Storyboard.TargetProperty="Color" To="#ffeeeeee" Duration="0:0:0.2" />
            <ColorAnimation Storyboard.TargetName="ButtonBorderGradientStop2" Storyboard.TargetProperty="Color" To="#ffcccccc" Duration="0:0:0.2" />
        </Storyboard>
        <Storyboard x:Key="MouseDownAnimation">
            <ColorAnimation Storyboard.TargetName="ButtonBorderGradientStop1" Storyboard.TargetProperty="Color" To="#ffc7c7ff" Duration="0:0:0.1" />
            <ColorAnimation Storyboard.TargetName="ButtonBorderGradientStop2" Storyboard.TargetProperty="Color" To="#ff9a9aff" Duration="0:0:0.1" />
        </Storyboard>
        <Storyboard x:Key="MouseUpAnimation">
            <ColorAnimation Storyboard.TargetName="ButtonBorderGradientStop1" Storyboard.TargetProperty="Color" To="#ffefefff" Duration="0:0:0.1" />
            <ColorAnimation Storyboard.TargetName="ButtonBorderGradientStop2" Storyboard.TargetProperty="Color" To="#ffc7c7ff" Duration="0:0:0.1" />
        </Storyboard>
    </ControlTemplate.Resources>


    <Border x:Name="ButtonBorder" CornerRadius="0" BorderBrush="#55aaaaaa" BorderThickness="1" Width="23" Height="22">
        <Border.Background>
            <LinearGradientBrush StartPoint="0,0" EndPoint="0,1">
                <GradientBrush.GradientStops>
                    <GradientStop x:Name="ButtonBorderGradientStop1" Color="#ffeeeeee" Offset="0.0" />
                    <GradientStop x:Name="ButtonBorderGradientStop2" Color="#ffcccccc" Offset="1.0" />
                </GradientBrush.GradientStops>
            </LinearGradientBrush>
        </Border.Background>
        <Image x:Name="ButtonIcon" Source="icons/searchicon_bw.png" Width="16" Height="16" />
    </Border>


    <ControlTemplate.Triggers>
        <Trigger Property="IsMouseOver" Value="True">
            <Trigger.EnterActions>
                <BeginStoryboard Storyboard="{StaticResource MouseOverAnimation}" />
            </Trigger.EnterActions>
            <Trigger.ExitActions>
                <BeginStoryboard Storyboard="{StaticResource MouseOutAnimation}" />
            </Trigger.ExitActions>
        </Trigger>
        <Trigger Property="IsPressed" Value="True">
            <Trigger.EnterActions>
                <BeginStoryboard Storyboard="{StaticResource MouseDownAnimation}" />
            </Trigger.EnterActions>
            <Trigger.ExitActions>
                <BeginStoryboard Storyboard="{StaticResource MouseUpAnimation}" />
            </Trigger.ExitActions>
        </Trigger>
    </ControlTemplate.Triggers> 
</ControlTemplate>
