Used to prevent users from updating, inserting, or deleting data in the dataset.
property ReadOnly: boolean default False;
Use the ReadOnly property to prevent users from updating, inserting, or deleting data in the dataset. By default, ReadOnly is False, meaning that users can potentially alter data stored in the dataset.
To guarantee that users cannot modify or add data to a dataset, set ReadOnly to True.
When ReadOnly is True, the dataset's CanModify property is False.
