Operation Property (RowChangedEventArgs)
Gets the EditOperation currently being executed. Allows Event handler to make further edits.
Create a record in a separate table in the Map within Row Events
// Use the EditOperation in the RowChangedEventArgs to append actions to be executed.
// Your actions will become part of the operation and combined into one item on the undo stack
private void HookRowCreatedEvent()
{
// subscribe to the RowCreatedEvent
Table table = MapView.Active.Map.GetLayersAsFlattenedList().OfType<FeatureLayer>().FirstOrDefault().GetTable();
RowCreatedEvent.Subscribe(MyRowCreatedEvent, table);
}
private void MyRowCreatedEvent(RowChangedEventArgs args)
{
// RowEvent callbacks are always called on the QueuedTask so there is no need
// to wrap your code within a QueuedTask.Run lambda.
// get the edit operation
var parentEditOp = args.Operation;
// set up some attributes
var attribs = new Dictionary<string, object> { };
attribs.Add("Layer", "Parcels");
attribs.Add("Description", "OID: " + args.Row.GetObjectID().ToString() + " " + DateTime.Now.ToShortTimeString());
//create a record in an audit table
var sTable = MapView.Active.Map.FindStandaloneTables("EditHistory").First();
var table = sTable.GetTable();
parentEditOp.Create(table, attribs);

Modify a record within Row Events - using EditOperation.Modify
private void HookChangedEvent()
{
// subscribe to the RowChangedEvent
Table table = MapView.Active.Map.GetLayersAsFlattenedList().OfType<FeatureLayer>().FirstOrDefault().GetTable();
RowChangedEvent.Subscribe(MyRowChangedEvent, table);
}
private void MyRowChangedEvent(RowChangedEventArgs args)
{
// RowEvent callbacks are always called on the QueuedTask so there is no need
// to wrap your code within a QueuedTask.Run lambda.
//example of modifying a field on a row that has been created
var parentEditOp = args.Operation;
// avoid recursion
if (_lastEdit != args.Guid)
{
//update field on change
parentEditOp.Modify(args.Row, "ZONING", "New");
_lastEdit = args.Guid;
}
