Description
TDataSetLast moves a target dataset to its last record.
Add TDataSetLast to an action list to allow users to navigate to the last record in a dataset. Controls such as menu items and tool buttons linked to this action cause the target dataset to move to the last record.
TDataSetLast is designed to work with a TDataSource component as its target. You can explicitly provide this target by setting the DataSource property, or you can allow the action to infer the data source from an active data-aware control. If you set DataSource, do not set it to a data source whose dataset is unidirectional. TDataSetLast automatically disables itself if it does not have a target data source attached to an active dataset that is not already on the last record.
