invalidate-section

Arguments: row-section column-section &optional redraw-now-p

Tells the operating system to invalidate the grid section specified by the arguments so that the operating system will tell the grid section to redraw itself after all other message processing has completed, or immediately if redraw-now-p is true.

Though the function invalidate is now recommended over most of the invalidate-* functions, it does not replace invalidate-section.

row-section may be either a row-section or a grid-row, and column-section may be either a column-section or a grid-column. So you could, for example, invalidate the area where a single grid-row crosses a whole column-section.

See also invalidate-whole-section.
