Check features after edit

mody_buchbinder

I am trying to get the OnEditCompleted event and do some checks (is the operation allowed) and actions (calc some default values).

The basic code is below. I have a few questions:

1) Do I need to get the OnRowCreated event too or this event is covering the same operations. Keep in mind that I have to check features added by GP tools (like append).

2) From my debug it looks that even this event is called multiply times with no reason - what can I do about it?

3) I could not find the way to abort the transaction.  I could not find something like RowChangedEventArgs.CancelEdit

I used EditCompletedEventArgs.FromException but it create Exception and does not end transaction.

 

Thanks

protected Task onEditCompleted(EditCompletedEventArgs args)
        {
            // check features one by one
            string message = "";
            Dictionary<MapMember, List<long>> createSelset = args.Creates.ToDictionary();
            foreach (var v in createSelset)
            {
                QueryFilter queryFilter = new QueryFilter();
                queryFilter.ObjectIDs = v.Value;
                FeatureLayer featureLayer = v.Key as FeatureLayer;                
                using (FeatureClass featureClass = featureLayer.GetFeatureClass())
                {
                    using (RowCursor cursor = featureLayer.GetFeatureClass().Search(queryFilter))
                    {
                        Feature currentFeat = null;
                        while (cursor.MoveNext())
                        {
                            currentFeat = (Feature)cursor.Current;
                            bool res = CheckFeatureCreate(currentFeat, out message);
                            if (res == false)
                            {
                                return Task.FromException(new Exception(message));
                            }
                            res = HandleFeatureCreate(currentFeat);
                            if (res == false)
                            {
                                return Task.FromException(new Exception("Problem with calc values"));
                            }
                        }  
                    }
                }
            }

Mody, EditCompletedEvent fires _after_ the fact, when the transaction has completed so it cannot be cancelled as it is not longer running. You may want to look at the EditCompletingEvent which also provides a CancelEdit capability. It is explained here: https://github.com/esri/arcgis-pro-sdk/wiki/ProConcepts-Editing#editcompletingevent.
