推荐答案
你介意解释你对环绕面板的要求吗?因为在大多数情况下，您可以使用 VirtualizedStackPanel 垂直和每行内的固定项目的组合.我在许多应用程序中都这样做过，因为与我从这个小工作中获得的简单性能和灵活性相比，制作一个环绕面板虚拟化是困难的.是的，方向可以轻松触发每行项目数"更改以补偿宽度更改.
Do you mind explaining your requirement around wrap panel. Because for most of the situations you might be able to make with a combination of VirtualizedStackPanel vertically and fixed items inside each row. I have done this way in many apps, because making a wrap panel virtualizing is hard compared to what easy performance and flexibility I can get from this small work around. Yes orientation can easily trigger for 'number of items per row' change to compensate the width changes.
