下面是我的数据,如附件所示

我仍然无法将所选菜单作为突出显示的菜单。在这方面的任何帮助都将非常有助于克服这个问题

先谢谢你

嗨,希拉格


请参阅附件

因此,关于您的模板设置,我有几点需要更改。但是,对于您的直接问题,请交换当前帧动画

<ObjectAnimationUsingKeyFrames Storyboard.TargetName="border"
                               Storyboard.TargetProperty="Background"
                               Duration="0">
    <DiscreteObjectKeyFrame KeyTime="0">
       <DiscreteObjectKeyFrame.Value>
          <SolidColorBrush Color="White"/>
       </DiscreteObjectKeyFrame.Value>
    </DiscreteObjectKeyFrame>
</ObjectAnimationUsingKeyFrames>
希望这有帮助,干杯

增加:

因此,由于我几乎从未真正测试过我的答案(我知道这是一个坏习惯,但通常情况下它们都是正确的)。在这种情况下,我没有时间去做任何事情,但下面是我要做的事情,这保证了我的答案是有效的,而且是更好的形式

拿着这里的东西

<StackPanel x:Name="border" Orientation="Horizontal">
                                <ContentControl x:Name="ContentContainer"  Foreground="{ThemeResource ApplicationForegroundThemeBrush}" HorizontalContentAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" VerticalContentAlignment="{TemplateBinding VerticalContentAlignment}">
                                    <StackPanel x:Name="insidestack"  >
                                        <StackPanel>
                                            <TextBlock Text="{Binding TitleofAccess}" FontWeight="SemiBold" TextAlignment="Center" Margin="10" VerticalAlignment="Center"  FontSize="20" Foreground="{ThemeResource ApplicationForegroundThemeBrush}"  />
                                        </StackPanel>
                                    </StackPanel>
                                </ContentControl>
                            </StackPanel>

既然我不明白为什么需要StackPanel或ContentControl,就这样交换它(最小的更改,但如果是我,我会重构所有的)


然后只需切换其中一个边框的可见性,以提供如下所示的背景。我们这样做是因为最好切换一个对象,而不是单独切换许多属性(这会给您警告,因为这样做是有原因的)



对不起,我没有时间把东西格式化。不过,我想重申一下,很明显,您对模板和VisualStaseMaMaGER的工作是新的,我会考虑重构这个控件,即使它是必要的小改动,因为它占据了很多部分,对于为什么它们按照您的方式进行操作是没有意义的。干杯
