By default, objects snap to the grid when it is visible.

A document that is displaying the page grid
Note that the page grid is always drawn upright (vertically and horizontally relative to the screen), even when you rotate the document view. Adjust the spacing of the gridlines, in the Options dialog box, in the Units and Grids panel, in the Grid size field.
