My user clicks into the "add" row at the bottom of the grid and keys the information in.  Then, on the last cell they hit the tab button.  The grid control adds a new row which fails validation because required fields are empty.  They then have to highlight the extra row and delete it before they can continue.

I was hoping there would be some property that governs this behavior.  I've used the TabNavigation property but since the user never technically gets to the "last" cell in the grid (since there is always a new template row) it doesn't work.  Is there a clean way to deal with this?
