public property TDataSet.BeforeScroll : TDataSetNotifyEvent |
BeforeScroll is triggered before the cursor changes position. This can happen with one of the navigation methods: TDataset.Next, TDataset.Prior, TDataset.First, TDataset.Last, but also with two of the editing operations:TDataset.Insert and TDataset.Delete. Raising an exception in this event handler aborts the operation in progress.
