WPF listview/gridview性能太差，建议 [英] WPF listview / gridview performance horrible, suggestions

问题描述

我有一个使用WPF ListView/GridView绑定到ObservableCollection的窗口.表演简直太恐怖了.每次添加/删除/修改项目时，应用程序都会尝试加载300-400个项目，并且CPU使用率会激增.剖析并没有发现任何明显的东西.

I have a window using a WPF ListView/GridView bound to an ObservableCollection. The performance is utterly horrific. The application chokes trying to load 300-400 items and CPU usage spikes each time an item is added/removed/modified. Profiling doesn't reveal anything obvious.

有人有什么建议吗?

推荐答案

检查以下属性:

VirtualizingStackPanel.IsVirtualizing="True"
VirtualizingStackPanel.VirtualizationMode="Recycling"
ScrollViewer.IsDeferredScrollingEnabled="True"
