If you don't want any grouping in your grid at all (even programmatically), then you should set the ViewStyleBand to Multi or Single  (as opposed to OutlookGroupBy). 

Mike,

Thanks for your Help.

Thanks,

Imran

Found it!  I guess it helped to post the message.    I guess I answered myself... should I be concerend?  :-)

it is an attribute on the XamDataGrid element:  

GroupByAreaLocation

="None"

I am trying to do this in the XAML.  I am using MVVM.   I will look at the windows init events.  If I have missed something as to the setup of the xml in XAML, please let me know.
