我有Grid个StackPanel个对象。
右侧的面板有4个垂直ToggleButton个对象。
4个 StackPanel 对象使用绑定作为可见性。例如：
<StackPanel x:Name="panelMaterialAndSettings" Grid.Row="3" Background="WhiteSmoke" Margin="2"
Visibility="{Binding IsChecked, ElementName=buttonMaterialAndSettings, Converter={StaticResource BoolToVis}, FallbackValue=Collapsed}">
效果很好。我无法理解的问题是父StackPanel。这也需要绑定Vibility属性，但如果现在可以看到4个子面板中的一个或多个，则它只返回true。
如果无法解决问题，我可以使用手动代码完成所有操作。
或者，它可以检查4个ToggleButtons。但我失败了。

其他人提请我注意MultiDataTrigger。
因此，我能够在这个主题上找到一个好的resource。
我能够提出以下建议：
<StackPanel.Style>
<Style TargetType="StackPanel">
<Setter Property="Visibility" Value="Visible" />
<Style.Triggers>
<MultiDataTrigger>
<MultiDataTrigger.Conditions>
<Condition Binding="{Binding ElementName=buttonStudentPicker, Path=IsChecked}" Value="False" />
<Condition Binding="{Binding ElementName=buttonDemonstrationPicker, Path=IsChecked}" Value="False" />
<Condition Binding="{Binding ElementName=buttonAssignmentHistory, Path=IsChecked}" Value="False" />
<Condition Binding="{Binding ElementName=buttonMaterialAndSettings, Path=IsChecked}" Value="False" />
</MultiDataTrigger.Conditions>
<Setter Property="Visibility" Value="Collapsed" />
</MultiDataTrigger>
</Style.Triggers>
</Style>
</StackPanel.Style>
