TImportOptions.LockedCellsAsReadonly Property
If true, locked cells in Excel will be imported as readonly cells in the grid. Note that by default all cells in Excel are locked but they won't be readonly unless the sheet is protected. So to use this property you need protected Excel sheets where cells have been unlocked, or all the file will be imported as readonly.
