How to switch between multiple pages in WPF?

In WPF, there are several methods available for switching between multiple pages.

1. By using the Frame control in WPF, you can nest one or more Frame controls in a Window and switch between pages using the navigation functionality of the Frame control. You can use the Navigate method of the Frame to switch between pages by passing the URI of the page or the page object.

// 在MainWindow的XAML中添加一个Frame控件
<Frame x:Name="mainFrame" />

// 在代码中使用Navigate方法切换页面
mainFrame.Navigate(new Page1()); // 切换到Page1页面
mainFrame.Navigate(new Page2()); // 切换到Page2页面

1. By using the TabControl control, you can add different page content to the TabItems in a WPF Window and switch between pages by selecting different TabItems in the TabControl.

// 在MainWindow的XAML中添加一个TabControl控件，以及多个TabItem
<TabControl>
    <TabItem Header="Page1">
        <local:Page1 />
    </TabItem>
    <TabItem Header="Page2">
        <local:Page2 />
    </TabItem>
</TabControl>

1. Using custom widgets: You can create a custom container to manage multiple pages, switching between them by controlling the visibility of the pages.

// 在MainWindow的XAML中添加一个自定义控件
<local:PageContainer Name="pageContainer" />

// 自定义PageContainer控件的代码
public class PageContainer : ContentControl
{
    public static readonly DependencyProperty CurrentPageProperty =
        DependencyProperty.Register("CurrentPage", typeof(UIElement), typeof(PageContainer), new PropertyMetadata(null));

    public UIElement CurrentPage
    {
        get { return (UIElement)GetValue(CurrentPageProperty); }
        set { SetValue(CurrentPageProperty, value); }
    }

    public PageContainer()
    {
        this.Loaded += PageContainer_Loaded;
    }

    private void PageContainer_Loaded(object sender, RoutedEventArgs e)
    {
        Content = CurrentPage;
    }
}

// 在代码中切换页面
pageContainer.CurrentPage = new Page1(); // 切换到Page1页面
pageContainer.CurrentPage = new Page2(); // 切换到Page2页面

Here are several common ways to switch between pages, choose the appropriate one based on specific needs.
