不知道这是否与XAML相关，但在我简单的Windows应用程序中，我手动创建了绑定，并添加了一个格式事件处理程序。

public FormMain() {
  InitializeComponent();

  Binding argBinding = new Binding("Enabled", uxCheckBoxArgsNull, "Checked", false, DataSourceUpdateMode.OnPropertyChanged);
  argBinding.Format += new ConvertEventHandler(Binding_Format_BooleanInverse);
  uxTextBoxArgs.DataBindings.Add(argBinding);
}

void Binding_Format_BooleanInverse(object sender, ConvertEventArgs e) {
  bool boolValue = (bool)e.Value;
  e.Value = !boolValue;
}

我使用类似于@Ofaim的方法

private bool jobSaved = true;
private bool JobSaved    
{ 
    get => jobSaved; 
    set
    {
        if (value == jobSaved) return;
        jobSaved = value;

        OnPropertyChanged();
        OnPropertyChanged("EnableSaveButton");
    }
}

public bool EnableSaveButton => !jobSaved;

类似于jevansio的回答，实现了一个名为BindableBool的类，具有isstrue和IsFalse属性，我可以将两个替代组件的IsVisible绑定到。

努格特：是的。可绑定布尔

I did something very similar. I created my property behind the scenes that enabled the selection of a combobox ONLY if it had finished searching for data. When my window first appears, it launches an async loaded command but I do not want the user to click on the combobox while it is still loading data (would be empty, then would be populated). So by default the property is false so I return the inverse in the getter. Then when I'm searching I set the property to true and back to false when complete.

private bool _isSearching;
public bool IsSearching
{
    get { return !_isSearching; }
    set
    {
        if(_isSearching != value)
        {
            _isSearching = value;
            OnPropertyChanged("IsSearching");
        }
    }
}

public CityViewModel()
{
    LoadedCommand = new DelegateCommandAsync(LoadCity, LoadCanExecute);
}

private async Task LoadCity(object pArg)
{
    IsSearching = true;

    //**Do your searching task here**

    IsSearching = false;
}

private bool LoadCanExecute(object pArg)
{
    return IsSearching;
}

然后，对于组合框，我可以直接绑定到IsSearching:

<ComboBox ItemsSource="{Binding Cities}" IsEnabled="{Binding IsSearching}" DisplayMemberPath="City" />

在视图模型中再添加一个属性，它将返回反向值。 然后把它绑定到按钮上。 像;

视图模型:

public bool IsNotReadOnly{get{return !IsReadOnly;}}

在xaml:

IsEnabled="{Binding IsNotReadOnly"}
