[UWP]自定义虚拟化面板 [英] [UWP] Custom virtualization panel

问题描述

嗨！

我需要开发自定义虚拟化面板。我有一个不同高度的项目列表，所以我选择`Canvas`就像`Panel`。

我看了几篇关于虚拟化的文章但是我找不到任何对UWP有用的东西平台（很多WPF实现与`ItemContainerGenertor`使用）。 

我已经基于`Canvas`制作了自定义面板但我不了解我应该如何进行自定义虚拟化： （ 
$
我应该检查面板中的滚动位置并通过`ItemContainerGenerator删除 - 添加项目，或者我应该在基于GridView的类中实现它还是实现一些接口？ 

Hi!
I need to develop custom virtualization panel. I have a list of items with different height so I choose `Canvas` like a `Panel`.
I looked at a couple of articles about virtualization but I didn't find anything useful for UWP platform (a lot of WPF implementation with `ItemContainerGenertor` using). 
I have already made custom panel based on `Canvas` but I don't understand how I should make custom virtualization :( 
Should I check scroll position in the panel and remove-add items by `ItemContainerGenerator` or I should make it in `GridView` based class or implement some an interface?
