wpf卡片布局

Question

我对 wpf 很陌生。如何从 Java 实现 CardLayout 功能？我有一个窗口，我需要根据用户操作完全切换内容，例如选项卡式窗格中的不同选项卡。

您可以创建多个页面并将它们托管在框架中。请参阅此处了解更多信息。

XAML：

<Window x:Class="CardLayout"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="CardLayout" Height="300" Width="300">
    <Grid>
        <Frame Height="200" HorizontalAlignment="Left" Margin="12,40,0,0" Name="frame1" VerticalAlignment="Top" Width="254" NavigationUIVisibility="Hidden" />

        <ComboBox HorizontalAlignment="Left" Margin="12,12,0,0" Name="comboBox1" VerticalAlignment="Top" Width="254" SelectedIndex="0" SelectionChanged="comboBox1_SelectionChanged">
            <ComboBoxItem>FirstPage</ComboBoxItem>
            <ComboBoxItem>SecondPage</ComboBoxItem>
        </ComboBox>
    </Grid>
</Window>

背后代码：

public partial class CardLayout : Window
{
    private Page[] pages = new Page[] {new Page1(), new Page2()};

    public CardLayout()
    {
        InitializeComponent();
    }

    private void comboBox1_SelectionChanged(object sender, SelectionChangedEventArgs e)
    {
        frame1.Content = pages[((ComboBox) sender).SelectedIndex];
    }
}
