This enumeration sets values for the ForeignKeyConstraint.AcceptRejectRule property. It determines what happens to child rows when you call the DataRow.AcceptChanges( ) method of the parent row. With the default value (None ) nothing happens. If you select Cascade , the DataRow.AcceptChanges( ) method is called automatically on all child rows when it is called on the parent.

The DataRow.AcceptChanges( ) method can be triggered in several ways. For example, if you call the DataTable.AcceptChanges( ) or DataSet.AcceptChanges( ) method, the AcceptChanges( ) method is called for every contained row. Also, if you update a data source using a data adapter, the DataRow.AcceptChanges( ) method is also called implicitly on each row once the change is committed to the data source.

public enum AcceptRejectRule {
   None = 0,
   Cascade = 1
}
