Specifies field or fields on which a Master-Detail link is based.
property MasterFields: WideString;
__property BSTR MasterFields;
Use MasterFields after setting the MasterSource or DataSource property to specify the names of one or more fields in another, master, dataset that are used to establish a Master-Detail relationship between this dataset and the master dataset. The master dataset is specified by assigning its data source to the MasterSource or DataSource property.
MasterFields is a string containing one or more field names in the master dataset. When the datasets are related based on two fields, separate field names with semicolons:
ADOTable2.MasterSource := DataSource1; ADOTable2.MasterFields := 'CustID;SaleDate'
ADOTable2->MasterSource = DataSource1; ADOTable2->MasterFields = "CustID;SaleDate"
Each time the current record in the master dataset changes, the new values in those fields are used to select corresponding records in this table for display.
