Krasimir, In your excellent response to the question I posted here: http://www.infragistics.com/community/forums/p/79384/400832.aspx#400832  I notice that if I do not add items to the ItemsSource in the constructor of the page, the grid does not automatically add a row when the user tabs past the last column. 

Note that the itemssource is not null - it just has no items.  This seems like inconsistent behavior - how do I fix it? 

Thank you,

Sam
