   // check if an object is currently "selected" 
   if (automation.CurrentEditObject != null) 
   { 
      // check if this object supports a pen 
      if (automation.CurrentEditObject.SupportsPen) 
      { 
         // change its pen 
         automation.BeginUndo(); 
         automation.CurrentEditObject.Pen = new AnnPen(Color.Blue, new AnnLength(2, AnnUnit.Pixel)); 
         automation.EndUndo(); 
         automation.Viewer.Invalidate(automation.CurrentEditObject.InvalidRectangle); 
      } 
   } 
}

Remarks

(Read only) The current object being edited is the AnnObject currently "selected" where its AnnEditDesigner is currently active.

This is the object that will be processed when calling any of the object processing methods of this AnnAutomation. For example, calling Copy will copy the CurrentEditObject into the clipboard.

You can change the CurrentEditObject by calling StartEditing.
