TTMSFMXGrid - margins & padding

With the TTMSFMXGrid, changing the margins and padding settings in the designer appears to have no visible effect. What do these settings do?

Margins and Padding behave as expected. Padding properties are used for children of the grid (for example adding a TButton client aligned). Margins are used when the grid itself is client aligned inside its parent. These properties are inherited from the base FMX Control.

Kind Regards,
