停用已在ContentControl标记中定义的ViewModel时遇到问题。我不想将Visibility设置为false，因为这似乎是不合适的解决方案。
这是它的外观，似乎在AllActive中，我们不需要激活每个项目：

<ContentControl Grid.Column="0" cal:View.Model="{Binding RandomScreenViewModel}"/>

这是在Conductor的“OneActive”模式下的外观。然后我们可以调用ActivateItem和DeactivateItem，其中Deactivate将实际关闭内容：

<ContentControl Grid.Column="0" x:Name="ActiveItem"}"/>

我希望激活的项目在AllActive期间关闭。这甚至是可能的吗？在我看来，它应该是可能的，从AllActive删除一个项目。
我有点n00b对使用导体，所以我希望任何人可以帮助我这一点。：D
