Question

我有一个Prism v4 / MEF / WPF解决方案，可以将模块视图加载到我的Avalon Dock中的DocumentPane中。我正在尝试在关闭事件上创建一个句柄（当按下'X'以关闭DocumentPane时）。我无法弄清楚，这是我的RegionAdapter类创建DockableContent的部分，也是我尝试处理close事件的部分（我试过3个事件）：

private void OnViewsCollectionChanged(object sender, NotifyCollectionChangedEventArgs e, IRegion region, DocumentPane regionTarget)
{
    if (e.Action == NotifyCollectionChangedAction.Add)
    {
        foreach (object item in e.NewItems)
        {
            UIElement view = item as UIElement;

            if (view != null)
            {
                DockableContent newContentPane = new DockableContent()
                {
                    Content = item,
                    Title = ((ITabViewInfo)view).TabViewTitle
                    Icon = ((ITabViewInfo)view).TabViewIcon
                };
                newContentPane.Closed += new EventHandler(newContentPane_Closed);
                newContentPane.Manager.DocumentClosed +=new EventHandler(Manager_DocumentClosed);
                newContentPane.Manager.DocumentClosing +=new EventHandler<System.ComponentModel.CancelEventArgs>(Manager_DocumentClosing);

                regionTarget.Items.Add(newContentPane);
                newContentPane.Activate();
            }
        }
    }
    else if (e.Action == NotifyCollectionChangedAction.Remove)
    {
        // this is never hit
        Debug.WriteLine("removed");
    }
}

这些事件永远不会被命中（我每个事件都有一个debug.writeline）：

        newContentPane.Closed += new EventHandler(newContentPane_Closed);
        newContentPane.Manager.DocumentClosed +=new EventHandler(Manager_DocumentClosed);
        newContentPane.Manager.DocumentClosing +=new EventHandler<System.ComponentModel.CancelEventArgs>(Manager_DocumentClosing);

如何处理DocumentPane的close事件？

我用于此RegionAdapter的代码基于http://blog.raffaeu.com/archive/2010/07/04/wpf-and-prism-tab-region-adapter-part-02.aspx

我不得不补充道：

IsCloseable = true
HideOnClose = false

Prism，AvalonDock Region Adapter（处理close DocumentPane事件）
