OperationManager Property (DockPane)

In This Topic

Gets the OperationManager associated with the DockPane.

Syntax

Visual Basic (Declaration)
C#

Public Overridable ReadOnly Property OperationManager As OperationManager

public virtual OperationManager OperationManager {get;}

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 its DAML id
  pane = FrameworkApplication.DockPaneManager.Find(dockPaneID);

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

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

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