If the data source contains fewer rows than the grid can display, the area below the AddNew row (or the last data row, if AllowAddNew is False) is left blank.
The color of this blank area depends on the setting of your system's 3D Objects color (or Button Face color), which is usually gray. You can eliminate this blank area with the EmptyRows property. The default value of this property is False, but if you set it to True, then the grid will display empty rows below the last usable data row.
Note that the empty rows cannot receive focus.
You can set both the EmptyRows and ExtendRightColumn properties to True to ensure that no blank areas appear within the interior of the grid.
