event _DataDOMEventSink_OnAfterChangeEventHandler OnAfterChange

This event handler does not allow users to cancel an operation.

The OnAfterChange event is typically used for changing data in a form after other changes have occurred — for example, making calculations or changing the structure of a form's underlying XML document.


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.

 if (e.IsUndoRedo)
  // An undo or redo operation has occurred and the DOM is read-only.
