比如初始化图片和点击后的图片

 public static readonly DependencyProperty NormalImageProperty = DependencyProperty.RegisterAttached(
           "NormalImage",
           typeof(ImageSource),
           typeof(ButtonAttachments),
           new PropertyMetadata(null));
        public static ImageSource GetNormalImage(DependencyObject obj)
            return (ImageSource)obj.GetValue(NormalImageProperty);
        public static void SetNormalImage(DependencyObject obj, ImageSource value)
            obj.SetValue(NormalImageProperty, value);
        public static readonly DependencyProperty PressedImageProperty = DependencyProperty.RegisterAttached(
            "PressedImage",
            typeof(ImageSource),
            typeof(ButtonAttachments),
            new PropertyMetadata(null));
        public static ImageSource GetPressedImage(DependencyObject obj)
            return (ImageSource)obj.GetValue(PressedImageProperty);
        public static void SetPressedImage(DependencyObject obj, ImageSource value)
            obj.SetValue(PressedImageProperty, value);
图片的位置放置
public static readonly DependencyProperty ImagePositionProperty = DependencyProperty.RegisterAttached(
            "ImagePosition",
            typeof(PositionEnumType),
            typeof(ButtonAttachments),
            new PropertyMetadata(PositionEnumType.Right));
        public static void SetImagePosition(DependencyObject element, PositionEnumType value)
            element.SetValue(ImagePositionProperty, value);
        public static PositionEnumType GetImagePosition(DependencyObject element)
            return (PositionEnumType) element.GetValue(ImagePositionProperty);
        public static readonly DependencyProperty ContentMarginProperty = DependencyProperty.RegisterAttached(
            "ContentMargin",
            typeof(Thickness),
            typeof(ButtonAttachments),
            new PropertyMetadata(default(Thickness)));
        public static void SetContentMargin(DependencyObject element, object value)
            element.SetValue(ContentMarginProperty, value);
        public static Thickness GetContentMargin(DependencyObject element)
            return (Thickness)element.GetValue(ContentMarginProperty);
接下来是Style的更改。Left表示图片在左边~
<DataTrigger Binding="{Binding Path=(res:ButtonAttachments.ImagePosition),RelativeSource={RelativeSource Self},Mode=OneWay}" Value="Left">
                <Setter Property="Template">

                                    <ContentPresenter RecognizesAccessKey="True"

                </Setter>
