Wpf 自定义控件三态ImageButton，无法绑定图像源

我正在创建自定义控件-图像按钮。其目的是使按钮没有任何背景或边框，只有3个图像处于正常状态，按下后鼠标悬停。当使用它-所有3个图像都应该有界。我从中获得了一些代码，但源代码是可靠的。我的代码是这样的：

Generic.xaml：

<ResourceDictionary
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:JoesControls">
<Style TargetType="{x:Type local:ImageButton}" x:Key="styledImageButton">
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type local:ImageButton}">
                <Grid
                    Margin="{TemplateBinding Control.Padding}"
                    HorizontalAlignment="{TemplateBinding Control.HorizontalContentAlignment}"
                    VerticalAlignment="{TemplateBinding Control.VerticalContentAlignment}"
                    SnapsToDevicePixels="{TemplateBinding UIElement.SnapsToDevicePixels}"
                    >
                    <Image Name="Normal" Source="{TemplateBinding NormalSource}"/>
                    <Image Name="Pressed" Source="{TemplateBinding PressedSource}" Visibility="Hidden"/>
                    <Image Name="Over" Source="{TemplateBinding MouseOverSource}" Visibility="Hidden"/>
                </Grid>
                <ControlTemplate.Triggers>
                    <Trigger Property="IsPressed" Value="True">
                        <Setter TargetName="Normal" Property="Visibility" Value="Hidden"/>
                        <Setter TargetName="Pressed" Property="Visibility" Value="Visible"/>
                    </Trigger>
                    <Trigger Property="IsEnabled" Value="False">
                        <Setter TargetName="Normal" Property="Visibility" Value="Hidden"/>
                        <Setter TargetName="Over" Property="Visibility" Value="Visible"/>
                    </Trigger>
                </ControlTemplate.Triggers>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

它编译时没有错误，但显然不起作用。源代码未绑定。我猜源代码的绑定设置不正确，但我已经尝试了一段时间，在谷歌上搜索它，但我失败了。谢谢你的帮助

我忘记了这个问题，尽管我已经实现了我想要的。今天我发现它还没有解决，所以我很高兴与您分享解决方案：
