Question

我有一个结构如下的项目：

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

我正在尝试设置窗口样式。窗口已设置样式，但标题栏按钮不起作用（触发器和悬停效果不存在，单击它们也无济于事）

这是我的代码：

App.xaml

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

DashboardStyle.xaml

Dashboard.xaml

<Window x:Class="Proj.Views.DashboardWindow"
    Style="{DynamicResource DarkWindowStyle}"
    ....>
</Window>

我在做什么错了？

Answer 1

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：写Command="{Binding Source={x:Static SystemCommands.MaximizeWindowCommand}}"等就足够了，而不是Command="SystemCommands.MaximizeWindowCommand"。

结果：

C＃WPF标题栏按钮无法使用样式
