An extended version of the IRelationList interface, that can be implemented by a data source to support master-detail relationships.
public interface IRelationListEx : IRelationList
Public Interface IRelationListEx Inherits IRelationList
This interface is an extended version of the IRelationList. By implementing the IRelationListEx interface, it’s possible to provide a different number of relationships for different master rows, and to customize the display captions of relationships.
A data source object can implement the IRelationListEx interface to enable master-detail mode, where you can dynamically provide detail data for particular master records. Currently, data source objects that implement the IRelationListEx interface are supported by the XtraGrid control. To learn more, see Working with Master-Detail Relationships in Code.
