C# 当PaneDisplayMode为LeftCompact时，如何使框架折叠和展开？

当我将PaneDisplayMode设置为LeftCompact时，NavigationPane在框架上重叠。我希望它的行为与离开PaneDisplayMode时相同。将其设置为LeftCompact或LeftMinimal会导致导航弹出按钮与框架重叠。但当导航菜单折叠时，左键会导致框架展开，就像它应该的那样。我想让LeftCompact做同样的事情

在

NavigationView

的样式中，您可以将

RootSplitView

的

DisplayMode

属性设置为

CompactInline

，该属性是

NavigationView

中的

SplitView

的名称，以实现该操作

请检查以下代码：

<VisualState.Setters>
    <Setter Target="RootSplitView.DisplayMode" Value="CompactInline" />
</VisualState.Setters>

打开文档大纲面板，查找并右键单击导航视图

导航菜单

编辑模板>编辑副本。然后，

NavigationView

的默认样式将复制到

页面。Resource

标记并应用到

NavigationView

控件

在样式中，找到名为

Compact

的

VisualState

，并添加以下代码：

<VisualState.Setters>
    <Setter Target="RootSplitView.DisplayMode" Value="CompactInline" />
</VisualState.Setters>
