ToolbarTray 工具栏内的按钮与 Caliburn 事件有关
Button inside ToolbarTray Toolbar problem with Caliburn Event
我没有找到用 Caliburn 激活按钮的解决方案。正如您在 MainToolBarTrayView.xaml 程序中看到的那样，按钮位于 toolbarTray/ToolBar 内。
因此，当我单击同名按钮时，我将执行函数 AlignBottom（例如）
我不明白为什么它不起作用，而且我在网上也没有看到类似的问题。可能是我做错了什么..谢谢你的帮助
我在 Github CockpitBuilder
上有我的全球项目
欢迎任何帮助....

我找到了解决问题的办法：
我只是 link 在 xaml 中命令并保持按钮控件未命名（我想避免与 caliburn 交互）
在MainToolBarTrayView.xaml
<Button Command="{Binding AlignBottom}" >
<Image Source="{StaticResource AlignBottom}" />
<Button.ToolTip>Align selected controls to the bottom of the first selected control.</Button.ToolTip>
</Button>
然后我在 viewModel 中定义所有命令（使用中继命令）
在 MainToolBarTrayViewModel.cs
using Caliburn.Micro;
using System;
using System.Windows.Input;
using IEventAggregator = CockpitBuilder.Core.Common.Events.IEventAggregator;
namespace CockpitBuilder.Views.Main.ToolBarTray
{

private bool _canAlignBottom;
public ICommand AlignBottom { get; private set; }
public MainToolBarTrayViewModel(IEventAggregator eventAggregator)
{
AlignBottom = new RelayCommand(o => cmdAlignBottom(), o => true);
}
public void cmdAlignBottom()
{
}
}
public class RelayCommand : ICommand
{
private Action<object> execute;
private Func<object, bool> canExecute;
public event EventHandler CanExecuteChanged
{
add { CommandManager.RequerySuggested += value; }
remove { CommandManager.RequerySuggested -= value; }
}
public RelayCommand(Action<object> execute, Func<object, bool> canExecute = null)
{

this.canExecute = canExecute;
