OperationManager Class

In This Topic

A collection of operations that users can undo and redo.

Syntax

C#
Visual Basic (Declaration)

public class OperationManager

Public Class OperationManager

Remarks

In general, undo operations are organized per ArcGIS.Desktop.Framework.Contracts.Pane and ArcGIS.Desktop.Framework.Contracts.DockPane. In other words, each Pane and DockPane manages its own operation stack. For example, operations added to map A are not visible to map B. The active window (Pane or DockPane) becomes the active OperationManager. When a window becomes active, its OperationManager is requested and connected to the undo/redo user interface.

Panes and DockPanes may however elect to share OperationManagers. For example, two Panes that are showing the same map will have the same OperationManager.

Example

Undo/Redo the Most Recent Operation

//undo
if (MapView.Active.Map.OperationManager.CanUndo)
  MapView.Active.Map.OperationManager.UndoAsync();//await as needed

//redo
if (MapView.Active.Map.OperationManager.CanRedo)
  MapView.Active.Map.OperationManager.RedoAsync();//await as needed
