Syntax
TableDelete(<Table control> [, <Subscript>])
<Table control>: Control name
Name of control to use. This control can correspond to:
  • a Table control.
  • a TreeView Table control.
  • WINDEV a Combo Box control with table.
If this parameter corresponds to an empty string (""), the Table control to which the current event belongs will be used.
<Subscript>: Optional integer
Subscript of row to delete.
If this parameter is not specified, the selected rows are deleted. If this parameter is not specified and if no row is selected, TableDelete has no effect.
Remarks

Use conditions

TableDelete can be used on:
  • a browsing or memory control.
  • a single-selection or multiselection control.

Deletion in a browsing Table or TreeView Table control

TableDelete deletes the corresponding record 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 TableDelete 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.
Example of error cases: Attempt to delete a row whose subscript corresponds to a row not selected in the visible part of Table control.

Locking the linked data file

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

Deletion in a memory Table control with a "Contains" filter

TableDelete called on a memory Table control that is using a "Contains" filter triggers the display of records that do not match the filter. The filters defined by the AAFs (Automatic Application Features) are canceled.
