如何在另一個頁面的多個框架中使用一個頁面物件？

我想要一個 Page 物件，它包含 Frames，它包含另一個 Page。當前結果如下所示： 但我希望頁面出現在所有框架中。 我怎樣才能做到這一點？ 包含 Frames 的頁面：

public partial class CombinedPage : Page
{
    public CombinedPage()
    {
        InitializeComponent();
        Frame1.Content = MainWindow.testPage;
        Frame2.Content = MainWindow.testPage;
        Frame3.Content = MainWindow.testPage;
        Frame4.Content = MainWindow.testPage;
    }
}

XAML：

<Grid>
    <Grid.RowDefinitions>
        <RowDefinition/>
        <RowDefinition Height="Auto"/>
        <RowDefinition/>
    </Grid.RowDefinitions>
    <Grid.ColumnDefinitions>
        <ColumnDefinition/>
        <ColumnDefinition Width="Auto"/>
        <ColumnDefinition/>
    </Grid.ColumnDefinitions>
        
    <GridSplitter Grid.Column="1" Grid.RowSpan="3" Width="5" Background="Black"
                VerticalAlignment="Stretch" HorizontalAlignment="Center" />
    <GridSplitter Grid.Row="1" Grid.ColumnSpan="3" Height="5" Background="Black"
                VerticalAlignment="Center" HorizontalAlignment="Stretch" />

    <Frame NavigationUIVisibility="Hidden" x:Name="Frame1" Grid.Row="0" Grid.Column="0"/>
    <Frame NavigationUIVisibility="Hidden" x:Name="Frame2" Grid.Row="0" Grid.Column="2"/>
    <Frame NavigationUIVisibility="Hidden" x:Name="Frame3" Grid.Row="2" Grid.Column="0"/>
    <Frame NavigationUIVisibility="Hidden" x:Name="Frame4" Grid.Row="2" Grid.Column="2"/>
</Grid>

在TestPageXAML：

<Grid>
    <Viewbox Stretch="Uniform" HorizontalAlignment="Stretch" VerticalAlignment="Stretch">
        <Label  Name="LiveTimeLabel" Content="%TIME%" HorizontalContentAlignment="Stretch"  HorizontalAlignment="Stretch" Foreground="#cccccc" VerticalAlignment="Stretch" FontWeight="Bold" />
    </Viewbox>
</Grid>

感謝您的任何建議！

編輯 1：好的，那么如果我只能使用 Page 物件一次，那么如何將它的位置從一幀更改為另一幀？我試過這個，但它似乎不起作用：

public partial class CombinedPage : Page
{
    public CombinedPage()
    {
        InitializeComponent();
        Frame1.Content = MainWindow.testPage;
        Frame2.Content = MainWindow.testPage;
        Frame3.Content = MainWindow.testPage;
        Frame4.Content = MainWindow.testPage;
    }

    private void butt1_Click(object sender, System.Windows.RoutedEventArgs e)
    {
        Frame1.Content = MainWindow.testPage;
    }

    private void butt2_Click(object sender, System.Windows.RoutedEventArgs e)
    {
        Frame2.Content = MainWindow.testPage;
    }

    private void butt3_Click(object sender, System.Windows.RoutedEventArgs e)
    {
        Frame3.Content = MainWindow.testPage;
    }

    private void butt4_Click(object sender, System.Windows.RoutedEventArgs e)
    {
        Frame4.Content = MainWindow.testPage;
    }
}

<Grid>
    <Grid.RowDefinitions>
        <RowDefinition/>
        <RowDefinition Height="Auto"/>
        <RowDefinition/>
        <RowDefinition Height="50"/>
    </Grid.RowDefinitions>
    <Grid.ColumnDefinitions>
        <ColumnDefinition/>
        <ColumnDefinition Width="Auto"/>
        <ColumnDefinition/>
    </Grid.ColumnDefinitions>
        
    <GridSplitter Grid.Column="1" Grid.RowSpan="3" Width="5" Background="Black"
                VerticalAlignment="Stretch" HorizontalAlignment="Center" />
    <GridSplitter Grid.Row="1" Grid.ColumnSpan="3" Height="5" Background="Black"
                VerticalAlignment="Center" HorizontalAlignment="Stretch" />

    <Frame NavigationUIVisibility="Hidden" x:Name="Frame1" Grid.Row="0" Grid.Column="0"/>
    <Frame NavigationUIVisibility="Hidden" x:Name="Frame2" Grid.Row="0" Grid.Column="2"/>
    <Frame NavigationUIVisibility="Hidden" x:Name="Frame3" Grid.Row="2" Grid.Column="0"/>
    <Frame NavigationUIVisibility="Hidden" x:Name="Frame4" Grid.Row="2" Grid.Column="2"/>
    <StackPanel Grid.Row="3" Grid.Column="0" Orientation="Horizontal">
        <Button x:Name="butt1" Width="50" Click="butt1_Click"/>
        <Button x:Name="butt2" Width="50" Click="butt2_Click"/>
        <Button x:Name="butt3" Width="50" Click="butt3_Click"/>
        <Button x:Name="butt4" Width="50" Click="butt4_Click"/>
    </StackPanel>
</Grid>

uj5u.com熱心網友回復：

您應該創建同一Page類的單獨實體：

public CombinedPage()
{
    InitializeComponent();
    Frame1.Content = new TestPage();
    Frame2.Content = new TestPage();
    Frame3.Content = new TestPage();
    Frame4.Content = new TestPage();
}

控制元件的單個實體 在可視化樹中只能出現一次，因此不能在多個中顯示相同的頁面實體Frame。
