Removing an Operation from the OperationsManager Undo/Redo Stack Doesn't Work

I have encountered what appears to be a bug in ArcGIS Pro 3.1.1 using the C# Pro SDK. I initially developed a method to remove unwanted operations from the OperationsManager undo/redo stack in version 2.9 of Pro, which worked perfectly. I was able to call the method whenever I wanted to, passing it an operation name, and it would remove it from the undo/redo stack. However, I have since upgraded my code to 3.X (currently 3.1.1) and the method no longer functions. It does not error. It just simply does nothing. Operations that I have requested to be removed are maintained, no matter what I do. Has there been a breaking change from 2.X to 3.X that has caused this behavior. The following is my method that used to work:

public static void RemoveUndoOperations(string opName) { if (MapView.Active?.Map == null) { return; } QueuedTask.Run(async () => { await Application.Current.Dispatcher.BeginInvoke(new Action(() => { OperationManager opManager = MapView.Active.Map.OperationManager; List<Operation> ops = opManager.FindUndoOperations(o => o.Name.Contains(opName)); ops.ForEach(op => opManager.RemoveRedoOperation(op)); }), DispatcherPriority.ApplicationIdle); }); }

NOTE: Removing the async QueuedTask and the Application.Current.Dispactcher.BeginInvoke does not make a difference. I have tried this, just for testing purposes, and it doesn't change things. The code still does not work. Nothing is removed from the undo/redo stack, no matter what I try. Once again, there are no errors. The code just fails to do anything. Any thoughts? Is this a new bug?

Hi Dave, can u try this:

FrameworkApplication.Current.Dispatcher.BeginInvoke(() => { OperationManager opManager = MapView.Active.Map.OperationManager; List<Operation> ops = opManager.FindUndoOperations( o => o.Name.Contains(opName)); ops.ForEach(op => opManager.RemoveUndoOperation(op)); });

I think u need to match the FindUndoOperations with a RemoveUndoOperation and vice versa for FindRedo.... and RemoveRedo....

Charlie,

Thank you! That fixed my problem. I am not sure why or how this worked in 2.9 when it definitely shouldn't have. I had the RemoveRedo... when I just needed RemoveUndo... Silly mistake!
