如何通过自定义按钮在wpf telerik RadTreeviewItem中添加命令事件并传递当前节点数据

<telerik:RadTreeView x:Name="treeView">
    <!-- TreeView的内容 -->
</telerik:RadTreeView>

<Button Content="自定义按钮" Click="CustomButton_Click"/>

public partial class MainWindow : Window
{
    public ICommand CustomCommand { get; set; }

    public MainWindow()
    {
        InitializeComponent();
        CustomCommand = new RelayCommand(ExecuteCustomCommand);
    }

    private void CustomButton_Click(object sender, RoutedEventArgs e)
    {
        var button = sender as Button;
        var data = button.CommandParameter; // 获取当前节点的数据
        CustomCommand.Execute(data); // 执行自定义命令，并传递当前节点的数据
    }

    private void ExecuteCustomCommand(object parameter)
    {
        // 在这里处理自定义命令的逻辑
        // 可以使用传递的当前节点数据（parameter）进行操作
    }
}

<telerik:RadTreeView x:Name="treeView">
    <telerik:RadTreeView.ItemTemplate>
        <HierarchicalDataTemplate ItemsSource="{Binding Children}">
            <StackPanel Orientation="Horizontal">
                <Button Content="自定义按钮" Command="{Binding DataContext.CustomCommand, RelativeSource={RelativeSource AncestorType=Window}}"
                        CommandParameter="{Binding}" />
                <TextBlock Text="{Binding Name}" />
            </StackPanel>
        </HierarchicalDataTemplate>
    </telerik:RadTreeView.ItemTemplate>
