我有很多困难试图实现一些应该是微不足道的事情。我使用的是在全局XAML资源文件中定义的隐式按钮样式。我只想改变用彩色动画变红。我试过很多不同的组合 Storyboard.TargetProperty 和 Storyboard.TargetName

提前谢谢。

<Style TargetType="Button" >
<Setter Property="Template">
    <Setter.Value>
        <ControlTemplate TargetType="Button">
            <Grid x:Name="grid" RenderTransformOrigin="0.5,0.5">
                <Grid.RenderTransform>
                    <TransformGroup>
                        <ScaleTransform/>
                        <SkewTransform/>
                        <RotateTransform/>
                        <TranslateTransform/>
                    </TransformGroup>
                </Grid.RenderTransform>
                <VisualStateManager.VisualStateGroups>
            <VisualStateGroup x:Name="FocusStates">
            <VisualState x:Name="Focused" >
                <Storyboard>
                    <ColorAnimation Storyboard.TargetProperty="(Rectangle.Fill).(SolidColorBrush.Color)" Storyboard.TargetName="Button" From="Green" To="Red" Duration="00:00:01" />
                </Storyboard>
            </VisualState>
            <VisualState x:Name="Unfocused"/>
            </VisualStateGroup>
            </VisualStateManager.VisualStateGroups>
        ...

因为我没有你其他的风格,我做了这个有两个边框和一个内容演示者。这将在聚焦后使按钮的背景从绿色变为红色。

<Style TargetType="Button" >
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="Button">
                <Grid x:Name="grid" RenderTransformOrigin="0.5,0.5">
                    <Grid.RenderTransform>
                        <TransformGroup>
                            <ScaleTransform/>
                            <SkewTransform/>
                            <RotateTransform/>
                            <TranslateTransform/>
                        </TransformGroup>
                    </Grid.RenderTransform>
                    <VisualStateManager.VisualStateGroups>
                        <VisualStateGroup x:Name="FocusStates">
                            <VisualState x:Name="Focused">
                                <Storyboard>
                                    <ColorAnimation Storyboard.TargetName="border"
                                                    Storyboard.TargetProperty="(Border.Background).(SolidColorBrush.Color)"
                                                    From="Green"
                                                    To="Red"
                                                    Duration="0:0:1" />
                                </Storyboard>
                            </VisualState>
                            <VisualState x:Name="Unfocused"/>
                        </VisualStateGroup>
                    </VisualStateManager.VisualStateGroups>
                    <Border BorderBrush="Transparent" BorderThickness="1" CornerRadius="4">
                        <Border x:Name="border" Background="White" BorderBrush="Black" BorderThickness="1" CornerRadius="4">
                        </Border>
                    </Border>
                    <ContentPresenter HorizontalAlignment="Center" VerticalAlignment="Center" Width="Auto"/>
                </Grid>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>
