For a relation specified in code in GetChildRows event, indicates whether GetParentRow is not available.

Syntax

Visual Basic
C#

'Declaration
 
Public Overridable Property OneWay As System.Boolean

public virtual System.bool OneWay {get; set;}

Remarks

This property has effect only for custom relations, those defined in code, with GetRowsEvent=True. If this property is set to True, code in C1.Data.C1DataSetLogic.GetParentRow event can be omitted, calling C1.Data.C1DataSetLogic.GetParentRow for this relation will throw exception. Set this property to True if it is difficult or simply unnecessary to reverse your algorithm enumerating child rows. Note that only GetChildRows is used for master-detail data binding, C1.Data.C1DataSetLogic.GetParentRow is not necessary.

In C1DataExpress, OneWay is always True for custom relations.
