    RowDeletedEvent Class
    In This Topic
    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
    Subscribe to Row Events
    protected void SubscribeRowEvent()
    {
      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)
    {
    }
    
    protected void OnRowChanged(RowChangedEventArgs args)
    {
    }
    
    protected void OnRowDeleted(RowChangedEventArgs args)
    {
    }
    Cancel a delete
    public void StopADelete()
    {
      // subscribe to the RowDeletedEvent for the appropriate table
      Table table = MapView.Active.Map.GetLayersAsFlattenedList().OfType<FeatureLayer>().FirstOrDefault().GetTable();
      RowDeletedEvent.Subscribe(OnRowDeletedEvent, table);
    }
    
    private Guid _currentRowDeletedGuid = Guid.Empty;
    private void OnRowDeletedEvent(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 
      if (_currentRowDeletedGuid == args.Guid)
        return;
    
      // cancel the delete if the feature is in Police District 5
      var fldIdx = row.FindField("POLICE_DISTRICT");
      if (fldIdx != -1)
      {
        var value = row[fldIdx].ToString();
        if (value == "5")
        {
          //cancel with dialog
          // Note - feature edits on Hosted and Standard Feature Services cannot be cancelled.
          args.CancelEdit("Delete Event\nAre you sure", true);
    
          // or cancel without a dialog
          // args.CancelEdit();
        }
      }
      _currentRowDeletedGuid = args.Guid;
    }
