The AddNew method will display a data entry row for the user to enter data for a new record. When this method is invoked, the AddNew row appears at the bottom of the group of rows (in the current band) that contains the active row. If there is no active row, and the control does not have enough context to determine where the add row should appear, an error occurs.
If you attempt to invoke the AddNew method on a read-only data source, you will also receive an error.
