在样式之间共享 VisualStateGroups答案

【问题描述】：

我有以下 xaml

<Style x:Key="GridStyle" TargetType="Grid">
    <Setter Property="VisualStateManager.VisualStateGroups">
        <Setter.Value>
            <VisualStateGroup x:Name="CommonStates">
                <VisualState x:Name="Normal"/>
                <VisualState x:Name="PointerOver">
                    <Storyboard>
                        <ObjectAnimationUsingKeyFrames Storyboard.TargetName="ButtonBackground" Storyboard.TargetProperty="BorderBrush">
                            <DiscreteObjectKeyFrame KeyTime="0" Value="{StaticResource ControlColour}" />
                        </ObjectAnimationUsingKeyFrames>
                    </Storyboard>
                </VisualState>
                <VisualState x:Name="Pressed">
                    <Storyboard>
                        <ObjectAnimationUsingKeyFrames Storyboard.TargetName="ButtonBackground" Storyboard.TargetProperty="Background">
                            <DiscreteObjectKeyFrame KeyTime="0" Value="{StaticResource ButtonCLickedBackground}" />
                        </ObjectAnimationUsingKeyFrames>
                    </Storyboard>
                </VisualState>
            </VisualStateGroup>
        </Setter.Value>
    </Setter>
</Style>

但我得到 VisualStateGroups 类型必须分配给 IList 但我需要在具有相同visualStateGroup然后不同的多个模板之间共享它，因此试图将VisualStateGroup变成一种我可以应用于我在按钮模板中使用的网格的样式。

 <Setter Property="Template">
       <Setter.Value>
            <ControlTemplate TargetType="ButtonBase">
                <Grid Style="{StaticResource GridStyle}" Background="Transparent">
                    <Border x:Name="ButtonBackground" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" CornerRadius="0" Background="{TemplateBinding Background}" Margin="{TemplateBinding Margin}" >
                    <ContentControl x:Name="ContentContainer" Foreground="{TemplateBinding Foreground}" HorizontalContentAlignment="{TemplateBinding HorizontalContentAlignment}" VerticalContentAlignment="{TemplateBinding VerticalContentAlignment}" Padding="{TemplateBinding Padding}">
                            <Grid>
                                <Rectangle Width="17" Height="5"  Fill="{Binding ElementName=ContentContainer, Path=Foreground}"/>
                            </Grid>
                        </ContentControl>
                    </Border>
                </Grid>
            </ControlTemplate>
        </Setter.Value>
    </Setter>

最后我似乎无法解决，谁能帮忙，还是我只需要在我需要的所有不同按钮样式中复制粘贴 VisualStateGroup？

VisualStateGroups 是附加属性，您不能将其设置为 Grid 样式中的依赖属性。如果您想在按钮模板中使用它。您可以像下面这样直接编辑 Button Xaml Style。

<ControlTemplate TargetType="Button">
    <Grid x:Name="RootGrid" Background="{TemplateBinding Background}">
        <VisualStateManager.VisualStateGroups>

            <VisualStateGroup x:Name="CommonStates">
                <VisualState x:Name="Normal">
                    <Storyboard>
                        <PointerUpThemeAnimation Storyboard.TargetName="RootGrid" />
                    </Storyboard>
                </VisualState>
                <VisualState x:Name="PointerOver">
                    <Storyboard>
                        <ObjectAnimationUsingKeyFrames Storyboard.TargetName="ButtonBackground" Storyboard.TargetProperty="BorderBrush">
                            <DiscreteObjectKeyFrame KeyTime="0" Value="Red" />
                        </ObjectAnimationUsingKeyFrames>
                        <ObjectAnimationUsingKeyFrames Storyboard.TargetName="RootGrid" Storyboard.TargetProperty="Background">
                            <DiscreteObjectKeyFrame KeyTime="0" Value="{ThemeResource ButtonBackgroundPointerOver}" />
                        </ObjectAnimationUsingKeyFrames>
                        <ObjectAnimationUsingKeyFrames Storyboard.TargetName="ContentPresenter" Storyboard.TargetProperty="BorderBrush">
                            <DiscreteObjectKeyFrame KeyTime="0" Value="{ThemeResource ButtonBorderBrushPointerOver}" />
                        </ObjectAnimationUsingKeyFrames>
                        <ObjectAnimationUsingKeyFrames Storyboard.TargetName="ContentPresenter" Storyboard.TargetProperty="Foreground">
                            <DiscreteObjectKeyFrame KeyTime="0" Value="{ThemeResource ButtonForegroundPointerOver}" />
                        </ObjectAnimationUsingKeyFrames>
                        <PointerUpThemeAnimation Storyboard.TargetName="RootGrid" />
                    </Storyboard>
                </VisualState>
                <VisualState x:Name="Pressed">
                    <Storyboard>
                        <ObjectAnimationUsingKeyFrames Storyboard.TargetName="ButtonBackground" Storyboard.TargetProperty="Background">
                            <DiscreteObjectKeyFrame KeyTime="0" Value="Blue" />
                        </ObjectAnimationUsingKeyFrames>
                        <ObjectAnimationUsingKeyFrames Storyboard.TargetName="RootGrid" Storyboard.TargetProperty="Background">
                            <DiscreteObjectKeyFrame KeyTime="0" Value="{ThemeResource ButtonBackgroundPressed}" />
                        </ObjectAnimationUsingKeyFrames>
                        <ObjectAnimationUsingKeyFrames Storyboard.TargetName="ContentPresenter" Storyboard.TargetProperty="BorderBrush">
                            <DiscreteObjectKeyFrame KeyTime="0" Value="{ThemeResource ButtonBorderBrushPressed}" />
                        </ObjectAnimationUsingKeyFrames>
                        <ObjectAnimationUsingKeyFrames Storyboard.TargetName="ContentPresenter" Storyboard.TargetProperty="Foreground">
                            <DiscreteObjectKeyFrame KeyTime="0" Value="{ThemeResource ButtonForegroundPressed}" />
                        </ObjectAnimationUsingKeyFrames>
                        <PointerDownThemeAnimation Storyboard.TargetName="RootGrid" />
                    </Storyboard>
                </VisualState>
                <VisualState x:Name="Disabled">
                    <Storyboard>
                        <ObjectAnimationUsingKeyFrames Storyboard.TargetName="RootGrid" Storyboard.TargetProperty="Background">
                            <DiscreteObjectKeyFrame KeyTime="0" Value="{ThemeResource ButtonBackgroundDisabled}" />
                        </ObjectAnimationUsingKeyFrames>
                        <ObjectAnimationUsingKeyFrames Storyboard.TargetName="ContentPresenter" Storyboard.TargetProperty="BorderBrush">
                            <DiscreteObjectKeyFrame KeyTime="0" Value="{ThemeResource ButtonBorderBrushDisabled}" />
                        </ObjectAnimationUsingKeyFrames>
                        <ObjectAnimationUsingKeyFrames Storyboard.TargetName="ContentPresenter" Storyboard.TargetProperty="Foreground">
                            <DiscreteObjectKeyFrame KeyTime="0" Value="{ThemeResource ButtonForegroundDisabled}" />
                        </ObjectAnimationUsingKeyFrames>
                    </Storyboard>
                </VisualState>
            </VisualStateGroup>
        </VisualStateManager.VisualStateGroups>
        <Border x:Name="ButtonBackground"
                BorderBrush="OldLace" BorderThickness="5" Background="White">
            <ContentPresenter x:Name="ContentPresenter" AutomationProperties.AccessibilityView="Raw" BorderThickness="{TemplateBinding BorderThickness}" BorderBrush="{TemplateBinding BorderBrush}" ContentTemplate="{TemplateBinding ContentTemplate}" Content="{TemplateBinding Content}" ContentTransitions="{TemplateBinding ContentTransitions}" HorizontalContentAlignment="{TemplateBinding HorizontalContentAlignment}" Padding="{TemplateBinding Padding}" VerticalContentAlignment="{TemplateBinding VerticalContentAlignment}" />
        </Border>
    </Grid>
</ControlTemplate>

用法

<Button Style="{StaticResource ButtonStyle1}" Content="ClickME" />
