如何从ControlTemplate中的多触发器启动彩色动画?

你试过MultiTrigger.entreactions吗?

在您的MultiTrigger中,您将拥有如下内容:

<MultiTrigger.EnterActions>
    <BeginStoryboard>
        <Storyboard>
            <ColorAnimation Storyboard.TargetName="YourObject'sName" Storyboard.TargetProperty="YourObject'sColorProperty" To="YourFavoriteColor" Duration"YourFavoriteNumber" />
        </Storyboard>
    </BeginStoryboard>
</MultiTrigger.EnterActions>

希望这有帮助!

编辑: 回答你在回答中提出的问题。 我没有试过,但我不确定你能不能像那样直接激活你的资源。与其将背景设置为资源,不如直接将其设置为SolidColorBrush:

<Border Name="Border" MinHeight="30" Margin="0,0,0,-1" BorderBrush="{DynamicResource ndt_DisabledForegroundBrush}"  BorderThickness="1,1,1,1" CornerRadius="0,0,0,0" > 
    <Border.Background>
        <SolidColorBrush x:Name="local_TabControlBackgroundBrush" Color="#CBCBCB" />
    </Border.Background>
    <ContentPresenter x:Name="ContentSite" VerticalAlignment="Center" HorizontalAlignment="Center" TextElement.FontStretch="UltraExpanded" TextElement.FontWeight="UltraBlack" ContentSource="Header" Margin="12,2,12,2" RecognizesAccessKey="True" /> 
</Border> 

然后你的动画就可以识别你的本地背景画笔了!

另外,我认为你可能需要把你的多触发到顶部高于你的其他触发器。我认为,每当你的多触发器为真时,基于IsSelected的触发器也是真的,并且会优先于它,因为它列在第一位。我可能错了,但我会再次检查,如果你没有得到错误,但你的多触发继续不工作。

是的,我以前试过,但在应用程序启动时出现运行时错误。我不知道为什么,但现在我毫无问题地找到了原因。你不允许在彩色动画中使用动态资源,就像我第一次尝试那样。因此,以下模板在启动时不会产生运行时错误:

<ControlTemplate x:Key="DefaultTabItemTemplate" TargetType="{x:Type TabItem}">
    <ControlTemplate.Resources>
        <SolidColorBrush x:Key="UnselectedForegroundBrush" Color="#414141" />
        <!-- Unique color for this template -->
        <SolidColorBrush x:Key="SelectedForegroundBrush" Color="#457581" />
        <!-- Unique color for this template -->
        <SolidColorBrush x:Key="MouseOverTextBrush" x:Name="local_MouseOverTextBrush" Color="#FFF2F2F2"/>
        <!-- Unique color for this template -->
        <SolidColorBrush x:Key="TabControlBackgroundBrush" x:Name="local_TabControlBackgroundBrush" Color="#CBCBCB" />
    </ControlTemplate.Resources>
    <Grid>
        <Border Name="Border" MinHeight="30" Margin="0,0,0,-1" Background="{DynamicResource TabControlBackgroundBrush}" BorderBrush="{DynamicResource ndt_DisabledForegroundBrush}"  BorderThickness="1,1,1,1" CornerRadius="0,0,0,0" >
            <ContentPresenter x:Name="ContentSite" VerticalAlignment="Center" HorizontalAlignment="Center" TextElement.FontStretch="UltraExpanded" TextElement.FontWeight="UltraBlack" ContentSource="Header" Margin="12,2,12,2" RecognizesAccessKey="True" />
        </Border>
    </Grid>
    <ControlTemplate.Triggers>
        <Trigger Property="IsSelected" Value="True">
            <Setter Property="Panel.ZIndex" Value="2" />
            <Setter TargetName="Border" Property="Background" Value="{DynamicResource ndt_TabControlBackgroundBrush}" />
            <Setter TargetName="Border" Property="BorderThickness" Value="1,1,1,0" />
            <Setter TargetName="ContentSite" Property="TextElement.Foreground" Value="{StaticResource SelectedForegroundBrush}" />
        </Trigger>
        <Trigger Property="IsEnabled" Value="False">
            <Setter TargetName="Border" Property="Background" Value="{DynamicResource ndt_DisabledBackgroundBrush}" />
            <Setter TargetName="ContentSite" Property="TextElement.Foreground" Value="{DynamicResource ndt_DarkGray}" />
            <Setter Property="Foreground" Value="{DynamicResource ndt_DisabledForegroundBrush}" />
        </Trigger>
        <MultiTrigger>
            <MultiTrigger.Conditions>
                <Condition Property="IsMouseOver" Value="True" />
                <Condition Property="IsSelected" Value="False" />
            </MultiTrigger.Conditions>
            <MultiTrigger.EnterActions>
                <BeginStoryboard>
                    <Storyboard>
                        <ColorAnimation Storyboard.TargetName="local_TabControlBackgroundBrush" Storyboard.TargetProperty="Color" To="{StaticResource ndt_NavigationAreaColor}" Duration="0:0:0.15" />
                    </Storyboard>
                </BeginStoryboard>
            </MultiTrigger.EnterActions>
        </MultiTrigger> 
    </ControlTemplate.Triggers>
</ControlTemplate>

这个名字是在模板资源中定义的-为什么他没有找到它?
