IPrxDataIslandHeaderCommon.IsHierarchical

Syntax

IsHierarchical: Boolean;

Description

The IsHierarchical property determines whether pop-up hierarchy is enabled.

Comments

Available values:

True. Pop-up hierarchy is enabled.
False. Pop-up hierarchy is disabled.

Example

Executing the example requires a form that contains the Button component with the Button1 identifier and the UiReport component with the UiReport1 identifier. A regular report with a configured hierarchy is used as a data source. The example is a handler of the OnClick event for the Button1 component.

Add links to the Dimensions, Matrix, Report system assemblies.

Sub Button1OnClick(Sender: Object; Args: IMouseEventArgs);
Var
    Rep: IPrxReport;
    DIs: IPrxDataIslands;
    DI: IPrxDataIsland;
    Dim: IDimInstance;
    DimProp: IPrxDataIslandDimension;
    Totals: IPrxDataIslandTotals;
    TotalsL: IPrxDataIslandTotals;
    DimModel: IDimensionModel;
    DIProp: IPrxDataIslandProperties;
    Top: IPrxDataIslandDimension;
    Level: IPrxDataIslandLevel;
Begin
    Rep := UiReport1.Report;
    DIs := Rep.DataIslands;
    DI := DIs.Item(0).Edit;
        // Pop-up hierarchy:
        DimModel := DI.Slice.TopHeader.Item(0).Dimension.Dimension;
        DIProp := DI.Properties;
        Top := DIProp.Dimension(DimModel);
        Level := Top.Level(DimModel.Levels.Item(0));
        If Not Level.IsHierarchical Then
            Level.Hierarchical := TriState.OnOption;
        End If;
        Debug.WriteLine("Pop-up hierarchy: ");
        Select Case Level.Hierarchical
            Case TriState.OnOption:
                Debug.WriteLine("is set");
            Case TriState.OffOption:
                Debug.WriteLine("is not set");
        End Select;
        Dim := DI.Slice.LeftHeader.Item(0).Dimension;
        DimProp := DIProp.Dimension(Dim.Dimension);
        // Parameters of totals by hierarchy
        Totals := DimProp.HierarchyTotals;
        Totals.Totals := TriState.OnOption;
        Totals.Method := BasicAggregatorOperation.Sum;
        // Parameters of totals by levels
        TotalsL := DimProp.LevelTotals;
        TotalsL.Totals := TriState.OnOption;
        TotalsL.Method := BasicAggregatorOperation.Sum;
    DI.Save;
End Sub Button1OnClick;

After executing the example the console window displays result of the checking if pop-up hierarchy is enabled for the set data area columns of regular report.

If the option is enabled, it will be disabled for the set area columns.

The regular report will contain configured totals by hierarchy and levels for the dimension located by in rows in the set data area.
