AcceptRejectRule serializable

AcceptRejectRule serializable

System.Data (system.data.dll) enum

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  }
