Examples

<!-- MainWindow.xaml -->

<Grid>
    <Grid.RowDefinitions>
        <RowDefinition Height="Auto" />
        <RowDefinition Height="*" />
    </Grid.RowDefinitions>
    <TitleBar Title="My App"
              IsPaneToggleButtonVisible="True"
              PaneToggleRequested="TitleBar_PaneToggleRequested">
    </TitleBar>

    <NavigationView x:Name="RootNavigationView" Grid.Row="1"
                    IsPaneToggleButtonVisible="False">
        <Frame x:Name="RootFrame" />
    </NavigationView>
</Grid>

// MainWindow.xaml.cs

private void TitleBar_PaneToggleRequested(TitleBar sender, object args)
{
    RootNavigationView.IsPaneOpen = !RootNavigationView.IsPaneOpen;
}

Remarks

When you use the TitleBar control with a NavigationView control, you should replace the navigation view's pane toggle button with the title bar's pane toggle button.

We recommend that you:

• Hide the pane toggle button in the NavigationView control. <NavigationView IsPaneToggleButtonVisible="False">
• Show the pane toggle button in the TitleBar. <TitleBar IsPaneToggleButtonVisible="True">
• Handle this event to toggle the value for the NavigationPane.IsPaneOpen property.

There is no inherent connection between the TitleBar's pane toggle button and the NavigationView. The TitleBar button simply raises this event to let you provide code to toggle the NavigationView's pane.
