Question

所以基本上..我在一个框架中添加了2个新页面，当我按下一个按钮时它会改变框架..

但如果我检查第一页上的复选框，我不会检查是否转到另一页然后返回第一页..

源代码

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;

namespace CheckboxesAndPages
{
    /// <summary>
    /// Interaction logic for MainWindow.xaml
    /// </summary>
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
        }

        private void button_Click(object sender, RoutedEventArgs e)
        {
            main.Content = new SecondPage();
        }

        private void button1_Click(object sender, RoutedEventArgs e)
        {
            main.Content = new thirdPage();
        }
    }
}

这2页没有源代码。

你每次都给它一个新的第二页

SecondPage secondPage = new SecondPage();
private void button_Click(object sender, RoutedEventArgs e)
{
    main.Content = secondPage;
}

为什么我的复选框在更改页面时取消选中？ WPF C＃.NET
