OperationManager Property (DockPane)

In This Topic

Gets the OperationManager associated with the DockPane.

Syntax

C#
Visual Basic (Declaration)

public virtual OperationManager OperationManager {get;}

Public Overridable ReadOnly Property OperationManager As OperationManager

Remarks

Each Pane and DockPane instance by default has their own OperationManager which represents an operation stack. The application's undo/redo controls work with the current OperationManager which is established by the active window. When a Pane or DockPane is activated, its OperationManager is requested. Derived classes can use this method to provide their own OperationManager. For example, Map Panes representing a specific Map, all share the same OperationManager.

Example

Dockpane undo / redo

// in order to find a dockpane you need to know it's DAML id
var pane = FrameworkApplication.DockPaneManager.Find("esri_core_contentsDockPane");

// get the undo stack
OperationManager manager = pane.OperationManager;
if (manager != null)
{
  // undo an operation
  if (manager.CanUndo)
    await manager.UndoAsync();

  // redo an operation
  if (manager.CanRedo)
    await manager.RedoAsync();

  // clear the undo and redo stack of operations of a particular category
  manager.ClearUndoCategory("Some category");
  manager.ClearRedoCategory("Some category");
}
