RowDeletedEvent Class
Members  Example 

ArcGIS.Desktop.Editing.Events Namespace : RowDeletedEvent Class
Occurs when a Row is deleted.
Object Model
RowDeletedEvent ClassSubscriptionToken Class
Syntax
public static class RowDeletedEvent 
Public MustInherit NotInheritable Class RowDeletedEvent 
Remarks
The RowDeletedEvent is published during the execution of the edit operation. Any modifications performed within the RowEvent handler can cause cascaded events to be generated. Make sure you have an exit condition to avoid infinite recursion. For example, if you are changing a feature attribute within a RowCreatedEvent or RowChangedEvent, consider tracking that feature's objectID to ignore the corresponding RowChangedEvent your attribute change will generate.

If you need to edit additional tables within the RowEvent you MUST use the ArcGIS.Core.Data API to edit the tables directly. Do NOT use a new edit operation to create or modify features or rows in your RowEvent callback.

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()}");
  }
}


private Guid _currentRowChangedGuid = Guid.Empty;

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

  var row = args.Row;

  // check for re-entry  (only if row.Store is called)

  var fldIdx = row.FindField("POLICE_DISTRICT");

    //  keep track of the row guid to avoid recursion

  }
}
