Property	Description
ChangeType	Gets the type of change.
Designer	Gets the designer responsible for the change.

NOTE: The object is not inserted into the Automation's container until this event has returned. This is to allow the user to cancel the Insertion operation.

Example

This example will subscribe to the AfterObjectChanged event of all automations and print out a message every time an object changes.

using Leadtools; 
using Leadtools.Annotations; 
using Leadtools.WinForms; 
using Leadtools.Drawing; 
 
public void AnnAutomation_AfterObjectChanged(AnnAutomationManager manager) 
{ 
   // subscribe to the AfterObjectChanged event of all automations 
   foreach (AnnAutomation automation in manager.Automations) 
      automation.AfterObjectChanged += new EventHandler<AnnAfterObjectChangedEventArgs>(automation_AfterObjectChanged); 
} 
 
private void automation_AfterObjectChanged(object sender, AnnAfterObjectChangedEventArgs e) 
{ 
   // print out a message 
   string message; 
 
   if (e.Objects != null && e.Objects.Count < 0) 
      message = string.Format("Objects Count: {0}, First object: {1}, Changed: {2}", e.Objects.Count, e.Objects[0].GetType().Name, e.ChangeType); 
   else 
      message = String.Format("Changed: {0}", e.ChangeType); 
 
   MessageBox.Show(message); 
}
