Works fine with a relative ancestor source. Or, just use a template colum instead of a combobox column and put a Combobox in there manually. Works fine with a relative ancestor source.

My only suggestion is to include the "using" statements in the code block. I picked them up from the zip file, though, so not a big deal. Elegant work-around that you clearly documented.

It works great. The bug has not been fixed in the latest release of the WPF Toolkit (June 2009, 25th), so I'll keep using your solution which is MVVM compliant. Keep up the good work :-) Thanks a lot !!! It works great.

I think this is pretty plainly a bug. I've solved this problem in my application a bit more directly, by setting the DataGridComboBoxColumn's ItemsSource binding in the code-behind of the control in which the DataGrid is contained. Not clean M-V-VM-wise, but very easily understood, I think.
