TDataSetAction implements the common behavior for actions that work with datasets. Each descendant class performs a specific database function. Do not use TDataSetAction directly in an application. Instead, use a TDataSetAction descendant such as TDataSetCancel, TDataSetDelete, TDataSetEdit, TDataSetFirst, TDataSetInsert, TDataSetLast, TDataSetNext, TDataSetPost, TDataSetPrior, or TDataSetRefresh. 

TDataSetAction ensures that the action is only enabled to work with a TDataSource component as its target. This TDataSource is first located as the data source that connects an active data-aware control to its source dataset. TDataSetAction saves this data source as the DataSource property, which descendants then use to perform their specific database functions.
