如何通過單擊一個按鈕並且僅使用 XAML 來選中或取消選中每個複選框？

所以，正如你所說：

我想讓它只與綁定一起工作

你有Window幾個CheckBoxes 和Button，它切換檢查狀態。CheckBox使用 Bindings設置es 到某些AllChecked屬性（我們將在代碼隱藏中創建它）：

XAML：

<Window x:Class="WpfApp.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

        mc:Ignorable="d"
        Title="MainWindow" 
        Height="150" 
        Width="400"
        Name="mainWindow"
        KeyDown="OnKeyDown">
    <Window.Resources>             
        <local:BooleanToStringConverter x:Key="BoolToStringConverter"/>
    </Window.Resources>
    <Grid>
        <StackPanel x:Name="checkBoxPanel" 
                    HorizontalAlignment="Left" 
                    VerticalAlignment="Top"
                    Margin="10,10,0,0">
            <!-- Binding CheckBoxes and disabling them -->
            <CheckBox IsChecked="{Binding ElementName=mainWindow,
                                          Path=AllChecked,
                                          UpdateSourceTrigger=PropertyChanged}" 
                      Content="CheckBox1" 
                      IsEnabled="False"/>
            <CheckBox IsChecked="{Binding ElementName=mainWindow, 
                                          Path=AllChecked, 
                                          UpdateSourceTrigger=PropertyChanged}"  
                      Content="CheckBox2"
                      IsEnabled="False"/>
            <!-- Same 3 other CheckBoxes -->
        </StackPanel>
        <!-- Button also binded to same property. -->
        <!-- With Converter its Text change between "Check All" and "Uncheck All" -->
        <Button x:Name="btnCheckUncheckAll"
                Content="{Binding ElementName=mainWindow, 
                                  Path=AllChecked, 
                                  UpdateSourceTrigger=PropertyChanged, 
                                  Converter={StaticResource BoolToStringConverter},
                                  ConverterParameter=btnCheckUncheckAll}" 
                HorizontalAlignment="Center"
                VerticalAlignment="Top" 
                Margin="0,10,0,0" 
                Width="100" 
                Height="32" 
                Click="ButtonCheckUncheckAll_Click"/>
    </Grid>
</Window>

CheckBox由於您的評論“...我不想單擊複選框”，示例中的所有es 都被禁用。正如@Shrimperator注意到的那樣，檢查一個將導致檢查所有CheckBoxes，因為它們綁定到相同的源（這是他們禁用的另一個原因）。BooleanToStringConverter使用AllChecked屬性值來設置“全部檢查”或“取消全部檢查”按鈕文本（請參閱其代碼隱藏部分的代碼）。我將按鈕x:Name作為參數傳遞給轉換器，以便將來能夠將轉換器用於其他不同的按鈕，而不僅僅是這個。

窗戶外觀：

代碼隱藏：

using System;
using System.ComponentModel;
using System.Globalization;
using System.Runtime.CompilerServices;
using System.Windows;
using System.Windows.Data;
using System.Windows.Input;

namespace WpfApp
{
    public partial class MainWindow : Window, INotifyPropertyChanged
    {
        private bool allChecked;
        // Single property each CheckBox binded to
        public bool AllChecked 
        {
            get => allChecked;
            set
            {
                allChecked = value;
                // Notify binded controls that we changed value
                OnPropertyChanged(nameof(AllChecked));
            }
        }

        // INotifyPropertyChanged implementation
        public event PropertyChangedEventHandler PropertyChanged;
        public void OnPropertyChanged([CallerMemberName] string propertyName = "") =>
            PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName));

        // Constructor
        public MainWindow() => InitializeComponent();

        // If button control clicked - check state on each CheckBox will change
        private void ButtonCheckUncheckAll_Click(object sender, RoutedEventArgs e) =>
            SwitchCheckState();

        private void OnKeyDown(object sender, KeyEventArgs e)
        {
            // If C button pressed - check state on each CheckBox will change
            if (e.Key == Key.C)
                SwitchCheckState();
        }

        // Simply switch between True and False
        private void SwitchCheckState() =>
            AllChecked = !AllChecked;
    }

    public class BooleanToStringConverter : IValueConverter
    {
        public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
        {
            if (parameter is string buttonName && buttonName == "btnCheckUncheckAll")
                return (bool)value == true ? "Uncheck all" : "Check all";

            return string.Empty;
        }

        public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture) =>
            string.Empty;
    }
}

所以我們有簡單的SwitchCheckState方法來改變和AllChecked之間的屬性。它由按鈕單擊（處理程序）或C（哎呀）按鍵（整個窗口上的處理程序）調用。我們以任何我們希望的方式改變屬性值，當和綁定在後面的某個地方做其他魔術時。TrueFalseButtonCheckUncheckAll_ClickOnKeyDownAllCheckedINotifyPropertyChanged

它是一個簡化的例子，沒有 ViewModels 和 DataContexting。如果您有其他問題、改進建議或需要其他解釋，請發表評論。
