IEditEvents2 Interface

Provides access to more editor events. Implement it to listen for specific events that occur during an edit session.

Product Availability

Available with ArcGIS Desktop.

When To Use

IEditEvents2 contains a collection of new editor events added at release 8.1.  For example, the editor now fires event notifcations whenever an edit sketch vertex is added, deleted, or moved.

Remarks

As with IEditEvents, always set the event object variable to nothing when the class is destructed to avoid circular reference problems.

When editing geometric network features, different combinations of edit events may be fired depending on the edit that is being performed. The OnVertexAdded  event is the fired before the OnCreateFeature, OnChangeFeature and OnDeleteFeature edit events under the following geometric network editing scenarios:

See the IEditEvents interface for a listing of those events that are fired when geometric network features are edited.  For more infomation on geometric networks and network features refer to the  IGeometricNetwork, INetworkFeature and IFeature interfaces.

[C#]

The following code shows how to wire edit events in C#.

public void WireEditEvents2()
{
  UID editorUid=new UIDClass(); 
  editorUid.Value="esriEditor.Editor";

  //You can get app from ICommand :: OnCreate() hook parameter  
  IEditor editor=app.FindExtensionByCLSID(editorUid) as IEditor;
  ((IEditEvents2_Event)editor).OnVertexAdded += 
    new IEditEvents2_OnVertexAddedEventHandler(OnVertexAdded);
}
void OnVertexAdded(IPoint point)
{
  System.Windows.Forms.MessageBox.Show("Vertex Added.");
}
