IPrxChartLegend.UndoRedo

Syntax

Description

The UndoRedo property determines parameters of Undo/Redo stack for external legend of the regular report chart.

Example

Executing the example requires a regular report with the REGULAR_REPORT identifier, in which a chart and an external legend are added. Add links to the Metabase, Report, Tab system assemblies.

Sub UserProc;
Var
    MB: IMetabase;
    Report: IPrxReport;
    Legend: IPrxChartLegend;
    Objects: ITabObjects;
    UnRed: IUndoRedo;
Begin
    MB := MetabaseClass.Active;
    Report := MB.ItemById("REGULAR_REPORT").Edit As IPrxReport;
    Objects := (Report.ActiveSheet As IprxTable).TabSheet.Objects;
    Legend := Objects.Item(1).Extension As IPrxChartLegend;
    UnRed := Legend.UndoRedo;
    UnRed.Enabled := True;
    UnRed.Limit := 5;
    (Report As IMetabaseObject).Save;
End Sub UserProc;

After executing the example the Undo/Redo stack is available for the external legend of the chart, the maximum number of undo/redo operations is limited to 50.
