In some cases, events related to changes in a form's underlying XML document may occur more than once. For example, when existing data is changed, an insert and delete operation occurs.

Example

In the following example, the OnAfterChange event handler is used to call a custom function that performs calculations:

JScript 
  function msoxd__ContactDates::OnAfterChange eventObj)
{
   if (eventObj.IsUndoRedo)
   {
      // An undo or redo operation has occurred and the DOM is read-only.
      return;
   }
   CalculateTotalCampaignCost();
}
