Name of Looper control to use.

Remarks

Use conditions

<Looper>.DeleteSelect can be used on a browsing or memory Looper control.

Deletion in a browsing Looper control

<Looper>.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 browsing Looper control

If the management of referential integrity is enabled (HSetIntegrity), HErrorIntegrity must be called after <Looper>.DeleteSelect 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 Looper control and Trigger

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

Management of 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, <Looper>.DeleteSelect deletes the specified row and unlocks the data file.
