The rooms lookup is used to retrieve a room if you do not know the room number.
Rooms are listed in order by room number. The list can be re-sorted.
You can re-sort the grid by clicking on an underlined column heading. It will sort in ascending order. Click it again to sort in descending order.
A triangle next to the column heading indicates the column by which the grid is currently sorted and whether it is sorted in ascending or descending
order.
Click Cancel to close the lookup without selecting a room.
