Feature not created in Featurelayer (Feature service) after adding field values programmatically

[PrashantKirpan]

Hi,

I'm trying to add some field values programmatically after feature is created. Code is working fine for feature class but not working with feature layer created from FeatureService.

After creating feature I assigned field value and can see feature is getting added in feature layer attribute table in Arcpro 2.7 but doesn't sync online. I manually saved all edit's but still data is not appearing in feature service. After refresh or zoom-in/out feature gets cleated from Arcpro attribute table also.

Here is my code:

{
 var mapProjItem = Project.Current.GetItems<MapProjectItem>().FirstOrDefault(item => item.Name.Contains("Map"));
 if (mapProjItem == null)
   return;

            QueuedTask.Run(() =>
            {
                var theMap = mapProjItem.GetMap();
                
                IEnumerable<FeatureLayer> featLayer = theMap.GetLayersAsFlattenedList().OfType<FeatureLayer>();
                foreach (FeatureLayer item in featLayer)
                { 
                   var layerTable = item.GetTable();
                   _rowCreateToken = RowCreatedEvent.Subscribe(onRowCreateEvent, layerTable);                        
             }

}
private Guid _currentRowChangedGuid = Guid.Empty;
private void onRowCreateEvent(RowChangedEventArgs args)
        {
           if (_currentRowChangedGuid == args.Guid)
              return;
            
           var row = args.Row;
           row["fieldname"] = "Some Value";
           _currentRowChangedGuid = args.Guid;
           row.Store();
           _currentRowChangedGuid = Guid.Empty; 
}

Is there anything additional I need to do to save feature service edits?

Any help would be appreciated.

I wonder if what you're seeing is related to this issue:

https://community.esri.com/t5/arcgis-pro-sdk-questions/rowcreatedevent-has-different-behavior-than-r...

Perhaps "We'll work on these" means a bug tracking number was assigned to it?

In a previous post (now deleted) I incorrectly assumed an OnChangeRow event was needed to make an attribute change stick.  I was wrong.  I now see that EditOperation.Modify works within the OnCreateRow event.  This is similar to the way ArcObjects requires editoperations.

private void Test4()
{
    var mapProjItem = Project.Current.GetItems<MapProjectItem>()
        .FirstOrDefault(item => item.Name.Contains("Map"));
    if (mapProjItem == null)
        return; // (no "Map" found)
    QueuedTask.Run(() =>
    {
        var featTable = mapProjItem.GetMap()
            .GetLayersAsFlattenedList()
            .OfType<FeatureLayer>()
            .Select(fLayer => fLayer.GetTable())
            .FirstOrDefault(t => t.GetDataConnection() is CIMStandardDataConnection);
        if (featTable == null)
            return; // (no featureservice layer found)

        var token1 = RowCreatedEvent.Subscribe(ea =>
        {
            // this doesn't stick ...
            //ea.Row["DisplayName"] = DateTime.Now.Ticks;

            // but this does (same way arcobjects needs an editoperation)...
            ea.Operation.Modify(ea.Row, "DisplayName", DateTime.Now.Ticks);
        }, featTable);
    });
}
