UnboundDeleteRow Event
The UnboundDeleteRow event is fired when the user deletes an existing row within an unbound grid (one with its DataMode property set to 1 - Unbound or 2 - Unbound Extended).
TDBGrid_UnboundDeleteRow (Bookmark As Variant)
Arguments
Bookmark is a variant that uniquely identifies the row to be deleted.
This event alerts your application that it must delete the row specified by the Bookmark argument from its unbound dataset.
The Bookmark argument contains a bookmark supplied by your application in the UnboundReadData, UnboundReadDataEx, or UnboundAddData event.
This event will not be fired if the AllowDelete property is set to False. Conversely, if you do not implement this event, then you must ensure that AllowDelete is never set to True.
Note
If the delete operation fails in the underlying data source, then you should set Bookmark to Null to inform the grid of the failure. This will cause the grid's Error event to fire. The row specified by Bookmark will remain selected.
