Navigating Data in Client Datasets
If an application uses standard data-aware controls, then a user can navigate through a client dataset's records using the built-in behavior of those controls. You can also navigate programmatically through records using standard dataset methods such as First, Last, Next, and Prior. For more information about these methods, see Navigating datasets.
Unlike most datasets, client datasets can also position the cursor at a specific record in the dataset by using the RecNo property. Ordinarily an application uses RecNo to determine the record number of the current record. Client datasets can, however, set RecNo to a particular record number to make that record the current one.
