    SankeyDiagramControl.TargetDataMember Property

    Specifies the name of a data member that contains target node labels.

    Namespace: DevExpress.XtraCharts.Sankey

    Assembly: DevExpress.XtraCharts.v25.1.UI.dll

    NuGet Package: DevExpress.Win.Charts

    #Declaration

    #Property Value

    Type Description
    String

    The name of a data source field that stores target node labels.

    #Remarks

    Specify the DataSource property to bind a Sankey diagram to data. You can assign an object of a class that implements one of the following interfaces: IList, IListSource or IBindingList.

    Then, define the names of data members that store data for source nodes, target nodes, and weights:

    • SourceDataMember - Specifies the name of a data member that contains data for source node labels.

    • TargetDataMember - Specifies the name of a data member that contains data for target node labels.

    • WeightDataMember (Optional) - Specifies the name of a data member that contains data for link weights. If unspecified, weights equal 1.
