Hi Peter,

What you’re experiencing is controlled by the property: editing.addNewRow.autoCreate
When this property is true, the grid automatically adds a new empty row (dimmed) when the user scrolls down past the last row using the grid’s scrollbar or keyboard arrows. If you want to turn off this behavior, you should set it to false. This will stop the grid from adding new rows automatically on scrolling past the bottom.

Best Regards,
