Use this dialog box to copy the current set of records from another dataset to the selected client dataset. This is useful when populating client datasets for use as lookup tables, or when testing client datasets at design-time. Select the dataset you want to copy from the list of datasets available to the current form, then click OK. To clear the records in a client dataset at design-time, set the dataset's Active property to true, then right-click the client dataset and choose Clear Data.
