IPivot.UndoRedo

Fore Syntax

UndoRedo: IUndoRedo;

Fore.NET Syntax

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

Description

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

Comments

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

Fore Example

Executing the example requires an express report with the EXPRESS_REPORT identifier containing a table.

Add links to the Express, Metabase, and Pivot system assemblies.

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

After executing the example an undo/redo stack is available for express report table; the number of available undo/redo operations is limited 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.Pivot;
Imports Prognoz.Platform.Interop.ForeSystem;

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