Description

Indicates whether the dataset is unidirectional.

IsUniDirectional indicates whether the dataset is a descendant of TCustomSQLDataSet. Unidirectional datasets raise exceptions on all navigation methods except for First and Next. They do not support filters, bookmarks, lookup fields, or any other features that require an internal record buffer. You can't use a unidirectional dataset as the source to a data-aware grid.
