如何在 WPF 中的窗口之间导航?(不是浏览器)

Question

我想开发一个基于 WPF 的桌面应用程序。如何在窗口中从一个窗口导航到另一个窗口的 C# 代码？换句话说，我尝试为在框架或边框中打开另一个窗口的单选按钮设置单击事件。

<Window x:Class="WpfNavigation2.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        xmlns:local="clr-namespace:WpfNavigation2"
        mc:Ignorable="d"
        Title="MainWindow" Height="350" Width="525" Loaded="Window_Loaded" Closing="Window_Closing">
    <Grid>
        <Border Margin="10,100,10,10" Background="AliceBlue">
            <Grid Name="contergrid">
            </Grid>
        </Border>

        <RadioButton x:Name="radioButton" Content="RadioButton1" HorizontalAlignment="Left" Margin="60,0,0,0" VerticalAlignment="Top" Click="btn1"/>
        <RadioButton x:Name="radioButton1" Content="RadioButton2" HorizontalAlignment="Left" Margin="60,37,0,0" VerticalAlignment="Top" Click="btn2"/>
        <RadioButton x:Name="radioButton2" Content="RadioButton3" HorizontalAlignment="Left" Margin="60,68,0,0" VerticalAlignment="Top" Click="btn3"/>
    </Grid>
</Window>

        private void btn1(object sender, RoutedEventArgs e)
        {
           //open window 1 in border
         }

您正在寻找的是ContentPresenter。您可以将所有类型的内容放在内容演示器中，例如控件

    <Border Margin="10,100,10,10" Background="AliceBlue">
        <ContentPresenter Name="contentFrame">
        </ContentPresenter>
    </Border>

    private void btn1(object sender, RoutedEventArgs e)
    {
        Grid grd = new Grid();
        grd.Background = new SolidColorBrush(Colors.HotPink);
        contentFrame.Content = grd; // replace me with your control / page / window1
    }
