Question

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>

但我得到的VisualStateGroups类型必须分配给IList 但是我需要在具有相同visualStateGroup的多个模板之间共享它然后不同，所以试图将VisualStateGroup变成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任何人的帮助，或者我只需要将VisualStateGroup复制粘贴到我需要的所有不同按钮样式上？

但我得到VisualStateGroups类型必须分配给IList但是我需要它在多个模板之间共享，这些模板具有相同的visualStateGroup然后不同所以试图将VisualStateGroup变成我可以应用于我在网格中使用的网格的样式按钮模板。

VisualStateGroups是附加属性，您无法将其设置为Grid样式中的依赖项属性。如果要在按钮模板中使用它。您可以直接编辑Button Xaml Style，如下所示。

<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>

<强>用法

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

在样式之间共享VisualStateGroups
