ArcGIS.Desktop.Framework.Contracts Namespace / DockPane Class / OperationManager Property
Example

In This Topic
    OperationManager Property (DockPane)
    In This Topic
    Gets the OperationManager associated with the DockPane.
    Syntax
    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");
    }
