</p><h2>Remarks</h2><p>
<p>This <a href="#" class="glossary" onclick="AppendPopup(this,'xdeventhandler')" onkeypress="AppendPopup(this,'xdeventhandler')">event handler</a> does not allow users to cancel an operation.</p><p>The <b class="bterm">OnAfterChange</b> event is typically used for changing data in a form after other changes have occurred<nbsp />— for example, making calculations or changing the structure of a form's underlying XML document.</p>
</p><p><b>Note</b> 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.</p><h2><a id="#example" name="#example">Example</a></h2><p>
<p>In the following example from the Events developer sample form, the OnAfterChange event handler is used to call a custom function that performs calculations:</p>
<pre><code>function msoxd__ContactDates::<b class="bterm">OnAfterChange</b>(eventObj)
{
if (eventObj.IsUndoRedo)
{
// An undo or redo operation has occurred and the DOM is read-only.
return;
}
CalculateTotalCampaignCost();
}</code></pre>
