这听起来你应该介绍一下你自己的Button班级。
我会这样做：
<my:GlowingArrowButton ArrowDirection="Left"/>
还有你的 generic.xaml：
<Style TargetType="my:GlowingArrowButton">
<Setter Property="Cursor" Value="Hand"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="my:GlowingArrowButton">
<Grid x:Name="grdRoot" RenderTransformOrigin="0.5,0.5">
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>

</Storyboard>
</VisualState>
<VisualState x:Name="Pressed"/>

和代码：
public class GlowingArrowButton : ButtonBase
{
public GlowingArrowButton()
{
DefaultStyleKey = typeof (GlowingArrowButton);
}
public ArrowDirection ArrowDirection
{
get { return (ArrowDirection) GetValue( ArrowDirectionProperty ); }
set { SetValue( ArrowDirectionProperty, value ); }
}
public static readonly DependencyProperty ArrowDirectionProperty =
DependencyProperty.Register( "ArrowDirection", typeof( ArrowDirection ), typeof( GlowingArrowButton ), new PropertyMetadata( default( ArrowDirection ) ) );
}
public enum ArrowDirection
{
Left,
Up,
Right,
Down
}
[编辑]
已编写但未经测试：
public class RotationTranslator : IValueConverter
{
public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
{
var arrowDirection = (ArrowDirection) value;
switch (arrowDirection)
{
case ArrowDirection.Left: return new RotateTransform{ Angle = 0 };
case ArrowDirection.Up: return new RotateTransform { Angle = 90 };
case ArrowDirection.Right: return new RotateTransform { Angle = 180 };
case ArrowDirection.Down: return new RotateTransform { Angle = -90 };
}
throw new InvalidOperationException();
}
public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture){throw new NotSupportedException();}
}
