NuGet Package: DevExpress.Data

Declaration

C#

IList GetDetailList(

    int relationIndex
)

VB.NET

Function GetDetailList(
    index As Integer,
    relationIndex As Integer
) As IList

Parameters

Name	Type	Description
index	Int32	An integer value that specifies the index of a master row in the data source.
relationIndex	Int32	An integer value that specifies the relationship.

Returns

Type	Description
IList	An object that implements the IList interface and represents detail data for a relationship.

Remarks

This method is called in turn for each relationship for each master row. Use this method to supply data for particular relationships.

The relationIndex parameter specifies a value between 0 and RelationCount - 1, where RelationCount is the number of relationships for the currently processed row. The number of relationships is identified:

• by the IRelationList.RelationCount property, if using the IRelationList interface;
• by the IRelationListEx.GetRelationCount method, if using the IRelationListEx interface.
