TIBDataSet.UniDirectional Property

Determines whether bidirectional cursors are enabled for the dataset.

property UniDirectional: Boolean;
__property Boolean UniDirectional;

Use UniDirectional to determine whether bidirectional cursors are enabled for this dataset.

Note: Do not confuse the UniDirectional property with the IsUniDirectional property inherited from TDataSet. IsUniDirectional indicates whether the dataset is a dbExpress dataset, which, in addition to using a unidirectional cursor, does not buffer records. UniDirectional is only concerned with whether the cursor permits backward or random navigation.
