WPF ToolKit DataGrid性能 [英] WPF ToolKit DataGrid Performance

问题描述

我有一个6列DataGrid，每列是一个RadioButton，以便用户可以选择1 6选项。大约有100行。我使用6个bool数据元素创建一个自定义类，然后使用约100个自定义类对象的列表绑定datagrid。有两个问题：

1. 绑定时间非常慢


2. 当我滚动数据网格某些行的检查值有时会消失。

在绑定到大量数据时，是否有任何已知的问题与datagrid ？以及如何提高性能。我正在使用WPF工具包的6月版本

谢谢

解决方案

您是否正在使用VirtualizingStackPanel？这将提高大屏幕上大量数据收集的性能。

I got a DataGrid with 6 column, each column is a RadioButton so that user can select 1 in 6 option. There are about 100 row. I make a custom class with 6 bool datamember, then bind the datagrid with a list of about 100 custom class object. There are 2 problem:

1. The binding time is very slow
2. When I scroll the data grid, sometime the check value of some row disappear.

Are there any known issues with datagrid when bind to a large amount of data like this? And how to improve the performance. I'm using the June Release of WPF Toolkit

Thanks

解决方案

Have you looked into using a VirtualizingStackPanel? This will improve performance for large collection of data for rendering on screen.
