RowChangedEventArgs Class
Members  Example 

ArcGIS.Desktop.Editing.Events Namespace : RowChangedEventArgs Class
Provides information about the changes that were made by a row event.
Object Model
RowChangedEventArgs ClassEditOperation ClassRow Class
Syntax
public sealed class RowChangedEventArgs 
Public NotInheritable Class RowChangedEventArgs 
Remarks
Use the properties on this class to determine the type of row event and the row that was affected. The event could be either a create, change or delete.
Example
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(OnRowCreated, layerTable);
    var rowChangeToken = RowChangedEvent.Subscribe(OnRowChanged, layerTable);
    var rowDeleteToken = RowDeletedEvent.Subscribe(OnRowDeleted, layerTable);
  });
}

protected void OnRowCreated(RowChangedEventArgs args)
{
  // RowEvent callbacks are always called on the QueuedTask so there is no need 
  // to wrap your code within a QueuedTask.Run lambda.

  // update a separate table when a row is created
  // You MUST use the ArcGIS.Core.Data API to edit the table. Do NOT
  // use a new edit operation in the RowEvent callbacks
  try
  {
    // update Notes table with information about the new feature
    var geoDatabase = new Geodatabase(new FileGeodatabaseConnectionPath(new Uri(Project.Current.DefaultGeodatabasePath)));
    var table = geoDatabase.OpenDataset<Table>("Notes");
    var tableDefinition = table.GetDefinition();
    using (var rowbuff = table.CreateRowBuffer())
    {
      // add a description
      rowbuff["Description"] = "OID: " + args.Row.GetObjectID().ToString() + " " + DateTime.Now.ToShortTimeString();
      table.CreateRow(rowbuff);
    }
  }
  catch (Exception e)
  {
    MessageBox.Show($@"Error in OnRowCreated for OID: {args.Row.GetObjectID()} : {e.ToString()}");
  }
}
