Changes to the DataGrid from v. 3.5sp1 (ToolKit) to .Net 4.0

I recently discovered that some functionality has been changed drastically in the DataGrid since it made it into the general 4.0 framework (Using Binding开发者_C百科Groups for one).

Can anyone point me at a list of changes (breaking or non-breaking)?

Unfortunately at least an official list does not seem to be available (which is a pity indeed), as informally confirmed by Lester Lobos answer to the similar question Official WPF DataGrid compared to WpfToolkit datagrid in the MSDN WPF forum:

the features should be similar for most scenarios... however, there isnt any documented list

Lester seems to be a Lead Software Engineer (QA) at Microsoft Corporation involved with the WPF team at least, so he should be in the know.

Only slightly related but still good to know in this context is Bob Baos answer to the more general question WPF Toolkit in WPF 4.0:

I get a mesage from a consultation in the internal WPF discussion. Unfortunately, the WPF Toolkit will not be updated to 4.0 anytime soon.
