    我有一个具有以下结构的项目: 

    Proj
├──Views
├   ├──Dashboard.xaml
├   ├──Dashboard.cs
├
├──Styles
├   ├──DashboardStyle.xaml
├
├──App.xaml
├──App.xaml.cs

    我想给窗户做个样式。窗口正在设置样式,但标题栏按钮不起作用(触发器和悬停效果不存在,单击它们也不起作用)

    这是我的代码:

    App.XAML 

    <ResourceDictionary>
    <ResourceDictionary.MergedDictionaries>
        <ResourceDictionary Source="Styles/DashboardStyle.xaml" />
    </ResourceDictionary.MergedDictionaries>
</ResourceDictionary>

    我做错什么了?

    您需要在窗口中为这些命令绑定命令,例如 

    public partial class DashboardWindow : Window
{
    public DashboardWindow()
    {
        InitializeComponent();

        this.CommandBindings.Add(new CommandBinding(SystemCommands.CloseWindowCommand, OnCloseWindow));
        this.CommandBindings.Add(new CommandBinding(SystemCommands.MaximizeWindowCommand, OnMaximizeWindow, OnCanResizeWindow));
        this.CommandBindings.Add(new CommandBinding(SystemCommands.MinimizeWindowCommand, OnMinimizeWindow, OnCanMinimizeWindow));
        this.CommandBindings.Add(new CommandBinding(SystemCommands.RestoreWindowCommand, OnRestoreWindow, OnCanResizeWindow));

    }

    private void OnCanMinimizeWindow(object sender, CanExecuteRoutedEventArgs e)
    {
        e.CanExecute = this.ResizeMode != ResizeMode.NoResize;
    }

    private void OnCanResizeWindow(object sender, CanExecuteRoutedEventArgs e)
    {
        e.CanExecute = this.ResizeMode == ResizeMode.CanResize || this.ResizeMode == ResizeMode.CanResizeWithGrip;
    }

    private void OnCloseWindow(object sender, ExecutedRoutedEventArgs e)
    {
        SystemCommands.CloseWindow(this);
    }

    private void OnMaximizeWindow(object sender, ExecutedRoutedEventArgs e)
    {
        SystemCommands.MaximizeWindow(this);
    }

    private void OnMinimizeWindow(object sender, ExecutedRoutedEventArgs e)
    {
        SystemCommands.MinimizeWindow(this);
    }

    private void OnRestoreWindow(object sender, ExecutedRoutedEventArgs e)
    {
        SystemCommands.RestoreWindow(this);
    }
}

    另一个提示:而不是 Command="{Binding Source={x:Static SystemCommands.MaximizeWindowCommand}}" ,写就足够了 Command="SystemCommands.MaximizeWindowCommand" 等。

    结果:
