IEaxAnalyzer.UndoRedo

Fore Syntax

UndoRedo: IUndoRedo;

Fore.NET Syntax

UndoRedo: Prognoz.Platform.Interop.ForeSystem.UndoRedo;

Description

The UndoRedo property returns parameters of express report undo or redo stack.

Comments

To use undo and redo stack parameters, the IUndoRedo.Enabled property must be set to True.

Fore Example

Executing the example requires that the repository contains an express report with the EXPRESS_REPORT identifier that contains a bubble chart.

Add links to the Express, Metabase system assemblies.

Sub UserProc;
Var
    Metabase: IMetabase;
    Analyzer: IEaxAnalyzer;
    UndoRedoAnalyzer: IUndoRedo;
Begin
    // Get repository
    Metabase := MetabaseClass.Active;
    // Get express report
    Analyzer := Metabase.ItemById("EXPRESS_REPORT").Edit As IEaxAnalyzer;
    // Get express report undo/redo stack
    UndoRedoAnalyzer := Analyzer.UndoRedo;
    // Set availability and number of undo/redo stack operations
    UndoRedoAnalyzer.Enabled := True;
    UndoRedoAnalyzer.Limit := 20;
    //Save changes
    (Analyzer As IMetabaseObject).Save;
End Sub UserProc;

After executing this example an undo/redo stack is available for express report; the number of available undo/redo operations is set to 20 operations.

Fore.NET Example

The requirements and result of the Fore.NET Example execution match with those in the Fore Example.

Imports Prognoz.Platform.Interop.Express;
Imports Prognoz.Platform.Interop.ForeSystem;

Public Shared Sub Main(Params: StartParams);
Var
    Metabase: IMetabase;
    Analyzer: IEaxAnalyzer;
    UndoRedoAnalyzer: IUndoRedo;
Begin
    // Get repository
    Metabase := Params.Metabase;
    // Get express report
    Analyzer := Metabase.ItemById["EXPRESS_REPORT"].Edit() As IEaxAnalyzer;
    // Get express report undo/redo stack
    UndoRedoAnalyzer := Analyzer.UndoRedo;
    // Set availability and number of undo/redo stack operations
    UndoRedoAnalyzer.Enabled := True;
    UndoRedoAnalyzer.Limit := 20;
    //Save changes
    (Analyzer As IMetabaseObject).Save();
End Sub;
