我craeted与MAINVIEW和2个其它视图（用户控件）的样品。 我已经放在一个按钮上的孩子认为接近，我想关闭这一观点。 有连接到该按钮的命令，并在靠近时pressed我问ViewModelLocator进行清洁。

按钮的观点仍显示.. 我在做什么错了？ 我怎样才能缩小与MVVM光一个用户控件看法？

 私人RelayCommand _closeCommand;
    公共RelayCommand CloseCommand
    {
        得到
        {
            如果（_closeCommand == NULL）
            {
                _closeCommand =新RelayCommand（（）=＆GT;
                   ViewModelLocator.ClearAllChannels（），

                   ）;
            }
            返回_closeCommand;
        }

    }
 

ViewModelLocator功能：

 公共静态无效ClearAllChannels（）
    {
        如果（_allChannels！= NULL）
        {
            _allChannels.Cleanup（）;
            _allChannels = NULL;
        }
    }
 

解决方案

在ViewModelLocator实际上并没有承载你的看法。它只是提供了一种方法来查找支持特定视图的视图模型。

所以，你需要问承载您的观点（大概窗口或框架）的控制来关闭它们。

I've craeted a sample with mainView and 2 other views (usercontrols). I've placed a button "close" on the child view and i want to close that view. there is a command attached to that button, and when close is pressed i ask the ViewModelLocator to clean it.

BUt- the view still being displayed.. What i'm doing wrong? How can i close a userControl view with mvvm-light?

    private RelayCommand _closeCommand;
    public RelayCommand CloseCommand
    {
        get
        {
            if (_closeCommand == null)
            {
                _closeCommand = new RelayCommand(()=>
                   ViewModelLocator.ClearAllChannels(),

                   );
            }
            return _closeCommand;
        }

    }

ViewModelLocator function:

    public static void ClearAllChannels()
    {
        if (_allChannels != null)
        {
            _allChannels.Cleanup();
            _allChannels = null;
        }
    }

The ViewModelLocator does not actually host your views. It just provides a way to look up the ViewModel that supports a particular view.

So you need to ask the control that hosts your views (probably a Window or Frame) to close them.
