问题描述
VirtualizingStackPanel.VirtualizationMode =回收/标准中实际上发生了什么?
What is actually happening in VirtualizingStackPanel.VirtualizationMode = Recycling/Standard.?
推荐答案
当VirtualizationMode设置为Recycling时，VirtualizingStackPanel将重用项目容器，而不必创建新的容器.如果我们从这里开始
When VirtualizationMode is set to Recycling, the VirtualizingStackPanel will reuse item containers instead of having to create a new one. If we start out with this
-------------------------
| Container 1 | Data 1 |
-------------------------
| Container 2 | Data 2 |
-------------------------
| Container 3 | Data 3 |
然后向下滚动一个位置，以便将数据1滚动到视图之外，将数据4滚动到视图中，然后Recyling将获取数据1的项目容器，并将其重新用于数据4.
And scroll one position down, so Data 1 is scrolled out of view and Data 4 is scrolled into view then Recyling will take the item container for Data 1 and reuse it for Data 4.
-------------------------
| Container 2 | Data 2 |
-------------------------
| Container 3 | Data 3 |
-------------------------
| Container 1 | Data 4 |
在为Item容器使用附加属性时，我遇到了一些问题，例如，如果我为Container 1进入了编辑模式，则为绿色背景.由于仍设置了Attachd属性，向下滚动，数据4也将具有绿色背景. .
I've had some problems with this when using attached properties for the Item container, e.g Green background if I have entered edit mode for Container 1. Scrolling down and Data 4 will also have Green background since the Attached Property was still set.
VirtualizationMode设置为Standard时，VirtualizingStackPanel将创建和丢弃项目容器，而不是重复使用它们.
When VirtualizationMode is set to Standard, the VirtualizingStackPanel will create and discard item containers instead of reusing them.
