As you add more controls the grid will grow either by rows or columns being added automagically (or not, if the ExpandStyle poroperty is set to emFixedSize). What’s more you can even determine how each cell will be sized: will it have a fixed size, or a percentage of the grid size – so you can have controls nicely uniformly distributed in a grid.

That’s all great when you know the design at design-time – and you know what number of controls you want to be hosted by the grid panel.
