    <ContextMenu x:Key="DocumentContextMenu">
        <MenuItem Command="{Binding Path=Model.CloseCommand}" Visibility="{Binding Path=IsEnabled, RelativeSource={RelativeSource Self}, Mode=OneWay, Converter={StaticResource BoolToVisibilityConverter}}">
            <MenuItem.HeaderTemplate>

注意这里的Model.CloseCommand的Model其实是DockingManager的DocumentsSource集合中的一项，该项对应一个含有CloseCommand属性的类实例，这样写其实就相当于覆盖掉原有CloseCommand

<xcad:DockingManager x:Name="dockingManager"
      AllowMixedOrientation="True"
      DocumentContextMenu="{StaticResource DocumentContextMenu}"
      BorderBrush="Black"
      FontFamily="Microsoft YaHei"
      DocumentClosing="dockingManager_OnDocumentClosing"
      DocumentsSource="{Binding Path=PanelsModel.Panels}"
      BorderThickness="1">

如DocumentContextMenu="{StaticResource DocumentContextMenu}"所示，直接指定DocumentContextMenu就ok了。

写得有点乱，权当是个简记。
