Deletion in a browsing Table or TreeView Table control

TableDeleteSelect deletes the corresponding records from the data file associated with the control. If items are linked to other data files, no modification is automatically performed on these linked data files.

Referential integrity and browsing Table or TreeView Table control

If the management of referential integrity is enabled (HSetIntegrity), HErrorIntegrity must be called after TableDeleteSelect to check the integrity. If an integrity error is detected, the row is not deleted and it remains visible in the control.

Deletion in a browsing Table control and Trigger

You have the ability to activate a trigger when deleting a record from a browsing Table control. See the documentation about HDescribeTrigger for more details.

Managing the errors

The ErrorOccurred variable is set to True if the deletion fails. To find out the error details, use ErrorInfo.

Locking the linked data file

If the data file is locked in the current process, TableDeleteSelect deletes the specified row and unlocks the data file.
