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

P/S: You can download my sample app to understand exactly the problem http://www.mediafire.com/file/jrmft4m4jwm/WpfApplication3.zip

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

If you can, switch to the .NET 4.0 version of DataGrid.

For me it reduced binding time from 80 secs to <0.5secs on 10000 rows, 10 columns.

Also, make sure to use UI Virtualization (turned on by default, but sometimes it gets disabled) WPF Toolkit DataGrid scrolling performance problems - why?
