TCustomSQLQuery.BeforeScroll property

Declaration

Description

Not described here; this is what TDataSet.BeforeScroll says of it:

Event triggered before the cursor changes position.

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