Specifies the data source component used for a Master-Detail relationship.
property MasterSource: TDataSource;
__property TDataSource MasterSource;
Use MasterSource to specify the name of the data source component whose DataSet property identifies a dataset to use as a Master table in establishing a Master-Detail relationship between this table and another one.
After setting the MasterSource property, specify which fields to use in the master table by setting the MasterFields property. At runtime each time the current record in the master table changes, the new values in those fields are used to select corresponding records in this table for display.
ADOTable2.MasterSource := DataSource1; ADOTable2.MasterFields := 'CustID';
ADOTable2->MasterSource = DataSource1; ADOTable2->MasterFields = "CustID";
