IRelationList.IsMasterRowEmpty(Int32, Int32) Method

When implemented by a class, returns a Boolean value that specifies whether a specific detail of a particular master row contains data.

Namespace: DevExpress.Data

Assembly: DevExpress.Data.v24.2.dll

NuGet Package: DevExpress.Data

#Declaration

bool IsMasterRowEmpty(
    int index,
    int relationIndex
)

#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
Boolean

A Boolean value that specifies whether a specific detail of a particular master row contains data.

#Remarks

This method is called in turn for each relationship for each master row (the number of relationships is determined by the IRelationList.RelationCount property). Handle this method to return a Boolean value which specifies whether a specific detail of a particular master row contains data.

When implementing a data source for a GridControl, the value returned by the IsMasterRowEmpty method is used if a master View’s GridOptionsDetail.AllowExpandEmptyDetails property is set to true (the grid allows the expansion of empty detail Views).
