Sorting data bound datagrid in XAML

Pretty much I want to accomplish what was asked about here: DataGrid - how to make Column so开发者_开发百科rting dynamic, to cater for when bound data changes?

I found one version here: http://wpf.codeplex.com/discussions/46939?ProjectName=wpf

What I really want is XAML version of manipulating CollectionViewSource Does anybody have sample on this?

I think exact "solution" which is really workaround is here and more.

What a pain :)
