Description

CellToGridZone is a TGridZone function used to get the grid zone where the specified cell is located. It is similar in nature to the MouseToGridZone method, but uses grid coordinates instead of mouse coordinates. The return value is one of the TGridZone enumeration values.

gzInvalid: Returned when ACol or ARow contain a negative number.
gzFixedCells: Returned when both ACol and ARow are in the FixedCols and FixedRows for the grid.
gzFixedCol: Returned when ACol is one of the FixedCols for the grid.
gzFixedRow: Returned when ARow is one of the FixedRows for the grid.
gzNormal: Default value returned for a cell that is neither a fixed column nor a fixed row.

CellToGridZone is used in the implementation of methods like MouseUp, CacheMouseDown, Clean, and LoadContent.
