未找到 WPF MVVM EventToCommand.cs

Question

我正在为我的一个应用程序使用 WPF MVVM Light。我在调试代码时发现错误是 "EventToCommand.cs not found" on Window Loaded Command.

我的代码是：

   xmlns:i="clr-namespace:System.Windows.Interactivity;assembly=System.Windows.Interactivity"
   xmlns:command="http://www.galasoft.ch/mvvmlight"

  <i:Interaction.Triggers>
    <i:EventTrigger EventName="Closing" >
        <command:EventToCommand Command="{Binding WindowCloseCommand}" PassEventArgsToCommand="True"  />
    </i:EventTrigger>
    <i:EventTrigger EventName="Loaded" >
        <command:EventToCommand Command="{Binding WindowLoadedCommand}" CommandParameter="{Binding RelativeSource={RelativeSource AncestorType={x:Type Window},Mode=FindAncestor}}" />
    </i:EventTrigger>
</i:Interaction.Triggers>

在视图模型中：

  public ICommand WindowLoadedCommand
    {
        get { return _windowLoadedCommand ?? (_windowLoadedCommand = new RelayCommand<MetroWindow>(OnWindowLoaded)); }
    }

  public void OnWindowLoaded(MetroWindow window)
  {

  }

请帮我找出解决这个问题的方法。

Answer 1

Use following code it might be work because in my case it's working.



<i:Interaction.Triggers>
        <i:EventTrigger EventName="Loaded">
            <i:InvokeCommandAction Command="{Binding WindowLoadedCommand}"/>
        </i:EventTrigger>
    </i:Interaction.Triggers>

ViewModel.cs,



   public ICommand WindowLoadedCommand
    {
        get { return new RelayCommand<object>(WindowLoadedCommandExecute); }

    }
    public void WindowLoadedCommandExecute(object obj)
    {

    }

我有 same problem，这最终为我解决了这个问题：

xmlns:Command="clr-namespace:GalaSoft.MvvmLight.Command;assembly=GalaSoft.MvvmLight.Platform"

<i:Interaction.Triggers>
    <i:EventTrigger EventName="Tap" >                
        <Command:EventToCommand  Command="{Binding Path=MyVM.MyCommand, Source={StaticResource Locator}}" 
                                 PassEventArgsToCommand="False"    
                                 CommandParameter="{Binding}"/>
    </i:EventTrigger>
</i:Interaction.Triggers>
