Detect Dynamo changes

[Anonymous]

Hi!

I am using Dynamic Model Update to handle changes made by the user. And I need to handle changes, made with Dynamo scripts separately. How can I check if changes that call my updater made by Dynamo?

I wanted to check if current transaction name contains "Dynamo", but how can I get current transaction name from the updater?

Thank you for reading 🙂

Hi everyone!

The question is still actual for me... While I cannot check transaction name from within updater Execute method I was thinking about other ways. For example, try to communicate to Dynamo Revit (not Sandbox) thread, but it's not separate from Revit thread , is it? If not... should I try to communicate to Dynamo window?

Still hoping that I am missing some official way

You can access the transaction names from DocumentChangedEventArgs Event

 Even in DB level you can access to transaction names via like this code snippet.

 public void ELementChangedEvent(object sender, DocumentChangedEventArgs args)
        { 
            ElementClassFilter filter2 = new ElementClassFilter(typeof(TextNoteType));
            Document doc = args.GetDocument();

            List<ElementId> AddedElements = args.GetAddedElementIds(filter2).ToList();
            List<ElementId> ModifiedElements = args.GetModifiedElementIds(filter2).ToList();

            string transactionName = args.GetTransactionNames().First();

            if (AddedElements.Count > 0)
            {
                TaskDialog.Show("ADDED ELEMENT", "A Text Note added to the document with: " + transactionName);

                doc.Delete(AddedElements.First());
            }
            if ( ModifiedElements.Count >0 )
            {
                TaskDialog.Show("MODIFIED ELEMENT","A Text Note modified with: " + transactionName);
            }
        }

Hope this sample helps.
