'Declaration
 
Public Event GetParentRow As GetListEventHandler

public event GetListEventHandler GetParentRow

Event Data

The event handler receives an argument of type GetListEventArgs containing data related to this event. The following GetListEventArgs properties provide information specific to this event.

Property	Description
List	This argument contains the list of rows. In events returning a list, create a new ArrayList object, fill it with rows and assign to the List argument. In events returning a single row (for example, GetParentRow:C1DataSetLogic event), add a single row to the list.
RelationName	The name of the relation (in GetRows:C1DataView event, empty if the view is not a child view).
Row	The row on which to base the list. In GetParentRow:C1DataSetLogic event, the parent row of the view, if it is a child view. In GetChildRows:C1DataSetLogic event, the parent row for which to return child rows.

Remarks

This event can be used in addition to GetChildRows event for two-way custom view relations. If the C1.Data.SchemaObjects.ViewRelation.OneWay property is set to True, the custom relation does not support getting parent row (note that only GetChildRows is used for master-detail data binding, GetParentRow is not necessary, it may only be needed in code). If C1.Data.SchemaObjects.ViewRelation.OneWay =False for a custom relation, C1DataObjects calls the GetParentRow event to obtain the parent row whenever C1DataRow.GetParentRow is called.
