WPF DataGrid与ListView性能对比与场景选择

开门见山的说

WPF DataGrid与ListView性能对比与场景选择

性能对比:

在Demo中,DataGrid与ListView默认开启虚拟化(可以理解为动态渲染,类似懒加载只渲染屏幕可以看见的地方)

DataGrid渲染10列50行随机字符280ms

ListView渲染10列50行随机字符80ms

场景选择:

ListView只生成需要展示的数据类型的控件,渲染相对DataGrid要快很多

DataGrid会生成编辑两种状态单元格(编辑与非编辑),如非必要不推荐使用(编辑单元格WPF硬伤/(ㄒoㄒ)/~~)
