DynamicResource颜色不工作

问题描述

我有以下的code：

<Color x:Key="SelectedColor">Gold</Color>

和包含颜色的TabItem风格

And a TabItem Style that contains the color

<VisualState x:Name="Selected">
    <Storyboard>
        <ColorAnimationUsingKeyFrames
            Storyboard.TargetProperty="(Shape.Fill).(GradientBrush.GradientStops)[0].(GradientStop.Color)"
            Storyboard.TargetName="InnerRectangle2">
            <EasingColorKeyFrame KeyTime="0" Value="{DynamicResource SelectedColor}"/>
        </ColorAnimationUsingKeyFrames>

原来我不能使用 DynamicResource 上的 EasingColorKeyFrame 。
我能做些什么来实现我的效果呢？

It turns out I can't use a DynamicResource on an EasingColorKeyFrame.
What can I do to achieve my effect?

我需要动态设置颜色，所以才换{DynamicResource SelectedColor}与{的StaticResource SelectedColor}是假表。

I need to set the color dynamically, so just swapping "{DynamicResource SelectedColor}" with "{StaticResource SelectedColor}" is off the table.

我创建了一个微小的解决方案来说明问题 - 所选标签应该是金色的，但实际上它是透明的，因为我想VSM不能解决命名为颜色 SelectedColor

I've created a tiny solution to demonstrate the problem - the Selected Tab should be Gold colored, but it's actually transparent, because I guess the VSM can't resolve the color named "SelectedColor"

推荐答案

我想出了一个办法，层次做到这一点。让你的对象的多个副本，然后只修改透明胶片是这样的：

I figured out a way to do it with layers. Make multiple copies of your object, and then just modify the transparencies like this:

<VisualState x:Name="Selected">
    <Storyboard>
        <DoubleAnimation Storyboard.TargetName="InnerRectangleBorder"
                         Storyboard.TargetProperty="Opacity"
                         To="0"
                         Duration="0:0:0" />

        <DoubleAnimation Storyboard.TargetName="InnerRectangleBorderMouseOver"
                         Storyboard.TargetProperty="Opacity"
                         To="0"
                         Duration="0:0:0.5" />

        <DoubleAnimation Storyboard.TargetName="InnerRectangleBorderSelected"
                         Storyboard.TargetProperty="Opacity"
                         To="1"
                         Duration="0:0:1" />
    </Storyboard>
</VisualState>
