Deleting records in a Table or TreeView Table control based on a data file

<Table>.DeleteSelect 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 Table or TreeView Table controls based on a data file

If the management of referential integrity is enabled (<Connection variable>.SetIntegrity), HErrorIntegrity must be called after <Table>.DeleteSelect to check the integrity. If an integrity error is detected, the row is not deleted and it remains visible in the control.

Deleting records in a Table control based on a data file and Trigger

You have the ability to activate a trigger when deleting a record from a Table control based on a data file. For more details, see the documentation about <Source>.DescribeTrigger.

Handling errors

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

Locking the linked data file

If the data file is locked in the current process, <Table>.DeleteSelect deletes the specified row and unlocks the data file.
