C# Execute命令未在资源字典代码中激发

我已经为它创建了资源字典和代码隐藏文件。 在XAML中，我定义了命令绑定并添加了执行处理程序：

<Button Grid.Row="2" Width="100" >
  <CommandBinding Command="Search" Executed="CommandBinding_Executed" />
</Button>

我不知道为什么在单击按钮时命令不执行，还有，为什么在我没有将CanExecute设置为true时按钮被启用。我也尝试将其设置为真，但CanExecute事件并没有启动。 以下是我如何使用资源字典：

public partial class MyWindow : Window {
        public MyWindow() {
            InitializeComponent();
            Uri uri = new Uri("/WPFLibs;component/Resources/StyleResources.xaml", UriKind.Relative);
            ResourceDictionary Dict = Application.LoadComponent(uri) as ResourceDictionary;
            this.Style = Dict["WindowTemplate"] as Style;
        }
    }

这不是将命令绑定到按钮的方式。它应该是这样的：

<Grid>
  <Grid.CommandBindings>
    <CommandBinding Command="Search" 
                    Executed="Search_Executed"
                    CanExecute="Search_CanExecute" />
  </Grid.CommandBindings>
  ...
  <Button Grid.Row="2" Width="100" Command="Search" />
  ...
</Grid>

<Grid>
  <Grid.CommandBindings>
    <CommandBinding Command="Search" 
                    Executed="Search_Executed"
                    CanExecute="Search_CanExecute" />
  </Grid.CommandBindings>
  ...
  <Button Grid.Row="2" Width="100" Command="Search" />
  ...
</Grid>

private void Search_Executed(object sender, ExecutedRoutedEventArgs e) {
    // do something
}

private void Search_CanExecute(object sender, CanExecuteRoutedEventArgs e) {
    e.CanExecute = ...; // set to true or false
}
