I am trying to use the option for tab - new row. But it does not actually create a row when I tab to the end of the grid. Is there something special that needs to be done to make this happen?

For reference I am using  7.1.2 and I added the grid to the form by dragging the dataset object from the data sources window. The binding navigator's plus sign will add a new row but tab new row doesn't actually do anything.

Any suggestions?
