<CheckBox Content="CheckBox"

如果你使用MVVM，你可以像这样使用事件触发器：

<CheckBox IsChecked="{Binding ServiceOrderItemTask.IsCompleted, Mode=TwoWay}" Content="{Binding ServiceOption.Name}">

    <i:Interaction.Triggers>
          <i:EventTrigger EventName="Checked">
                 <i:InvokeCommandAction Command="{Binding DataContext.IsCompletedCheckedCommand, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type t:RadGridView}}}" CommandParameter="{Binding}"/>
           </i:EventTrigger>

           <i:EventTrigger EventName="Unchecked">
                 <i:InvokeCommandAction Command="{Binding DataContext.IsCompletedUncheckedCommand, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type t:RadGridView}}}" CommandParameter="{Binding}"/>
           </i:EventTrigger>
    </i:Interaction.Triggers>

字符串

它能满足你的要求-

<CheckBox CommandParameter="{Binding}"
          Command="{Binding DataContext.YourCommand,
          RelativeSource={RelativeSource FindAncestor,
                           AncestorType={x:Type UserControl}}}"
          Content="{Binding Path=Name}">

• 将System.Windows.Interactivity添加到项目引用中。
• 将xmlns:i="http://schemas.microsoft.com/expression/2010/interactivity"添加到XAML命名空间。

<CheckBox IsChecked="{Binding SomeBoolProperty, Mode=OneWay}" Content="Check Meee!">

我在ViewModel上实现INotifyPropertyChanged，如下所示：

public event PropertyChangedEventHandler PropertyChanged;
private void OnPropertyChanged(string name) => PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(name));

我的ViewModel的SomeBoolProperty看起来像这样：

private bool _SomeBoolProperty = false;
public bool SomeBoolProperty { 
    get => _SomeBoolProperty;
    set { 
        _SomeBoolProperty = value; 
        OnPropertyChanged(nameof(SomeBoolProperty)); 
    } 
}

我在这里使用RelayCommand作为我的命令实现https://stackoverflow.com/a/22286816/336753。
我的ViewModel上的命令看起来像这样：

public ICommand MyOnCheckedCommand { get; } = new RelayCommand(o => {
    // Do something here.
    SomeBoolProperty = true;
});
public ICommand MyOnUncheckedCommand { get; } = new RelayCommand(o => {
    // Do something else here.
    SomeBoolProperty = false;
});

我得到了这个问题，试图找到一种方法来重用我已经在我的ViewModel上的两个命令。一个在选中时调用，一个在未选中时调用。我也在一些按钮上使用它们，所以不想添加额外的参数化命令。人们在这里询问ViewModel实现，所以添加这个答案来完成Igor_S的一个。希望它有帮助。

我迟到了.我用Rohit Vats的答案，想出了这个代码。
这个例子是一个工作代码提取，它只是在这里帮助理解每个方面。它是一个图钉，可以是活动的或不活动的，它使用DelegateCommand。你可能也可以使用RelayCommand或任何其他类似的类来做同样的工作。
命令：

using System.Windows.Input;

namespace HQ.Wpf.Util.Command
{
    public class StandardCommand
    {
        public static RoutedUICommand PinPropertyGrid = new RoutedUICommand("Pin property grid", "PinPropertyGrid", typeof(StandardCommand));

当你只需要复选框的状态（选中或未选中）时，你不需要参数。当你使用这个代码时，你可以检测复选框的状态：

CheckBox box = e.OriginalSource as CheckBox;

if(box.IsChecked.Value)
    DoThis();
else
    DoAnotherMethod();

字符串
“e”是命令中的ExecutedRoutedEventArgs-Parameter。您需要box. Isalog.Value，因为box. Isalog来自类型bool？。
