RowCreatedEvent or RowChangedEvent

Question

I want to catch all Row Created and Row Changed events.  When i catch them, to have edit events based on which class was being edited.  However, i can't figure out where to subscribe at.  When i do the following in the Configuration Manager, ArcGIS Pro constantly says "Drawing".  In ArcObjects, i did all this work in an "Editor" extension I made that caught all of the Creates, Changes, and Deletes.  I think this is what i need, but I can't figure out where to put the subRowEvent?

protected override void OnApplicationInitializing(CancelEventArgs cancelEventArgs)
 {
 var theme = FrameworkApplication.ApplicationTheme;
 //ApplicationTheme enumeration
 if (FrameworkApplication.ApplicationTheme != ApplicationTheme.Dark)
 {
 //Dark theme
 FrameworkApplication.ApplicationTheme = ApplicationTheme.Dark;
 }

subRowEvent();
 }

protected void subRowEvent()
 {
 QueuedTask.Run(() =>
 {
 //Listen for row events on a layer
 var featLayer = MapView.Active.GetSelectedLayers().First() as FeatureLayer;
 var layerTable = featLayer.GetTable();

//subscribe to row events
 var rowCreateToken = RowCreatedEvent.Subscribe(onRowEvent, layerTable);
 var rowChangeToken = RowChangedEvent.Subscribe(onRowEvent, layerTable);
 var rowDeleteToken = RowDeletedEvent.Subscribe(onRowEvent, layerTable);
 });
 }

protected void onRowEvent(RowChangedEventArgs args)
 {
 Console.WriteLine("RowChangedEvent " + args.EditType.ToString());
 }

We had some constraints on our database an ID and some other fields are required.  So when we tried to create the feature, Pro would signal an error as the insert wasn't allowed.  We removed the constraint now, as we will require the user to enter them, or we will auto enter them in the OnRowCreate event.  We also need to do this because the definition query uses certain attributes to determine what the user can see.

Basically we are prompting a user with a dialog box whenever a new feature is created.  Before the dialog appears, we set some required attributes about their location.  The user then is required on the form to enter certain information.  They will not be able to close the form unless all required attributes are satisfied.  If they hit cancel on this new feature form, the feature is then deleted.

Were looking into a few things here. What constraints do you have on the fields?

There is no exposed event before the row is created. The other opportunity to change field values before the feature is created is by either manipulating the template field values, if the user is using a template to create features, or through the create methods on editoperation in the sdk.

My problem is, is that my RowChangedEvent or Row Created Event are never hit, because the row can't be inserted without a certain required attribute value being present.  I get the "Bad Syntax in request" in ArcGIS Pro, before any events even get hit.  The database requires 4 of my attributes be populated. Do i have to remove database constraints in order to use the feature service model?

Is there an event that is triggered before the RowCreated that I could prompt the user for values or modify the rows, much like we have done here for row created/changed.
