If i remove the SelectColumn, all is working fine.

I'm using the internal build of WPF Controls : 2011.3.1227.40
I tried with stable build and latest internal builds and the behavior is the same.

Any help ?

Thanks.

Hello Bernard,

I've tried to reproduce the problem you reported but to no avail. Can you check the attached test application and let me know if you are able to reproduce the exception? Is there something specific in your scenario that I've missed?
