根据我设置的msdn建议
<Setter Property="EnableRowVirtualization" Value="True"/>
<Setter Property="EnableColumnVirtualization" Value="True"/>
但是我认识到如果我将EnableColumnVirtualization设置为true，当我滚动到水平时，它会导致所选项目被更改并使其变得不可思议。当触发所选项目时，我用MvvmLight.Messaging相互更新了两个面板。每次滚动时，水平滚动都会变得很痛苦，它会触发selectitem更改并弹出错误消息，如下所示。

当我将虚拟化设置为false时，一切都很顺利。所以我想知道，是这样的，我不能使用虚拟化，或者是否有解决方法？
