This member can be accessed only by forms running in the same domain as the currently open form, or by forms that have been granted cross-domain permissions.
Examples
In the following example, the Source property of the DataDOMEventObject object is used to return a reference to the XML DOM node that caused the initial change. If the node name matches certain criteria, a custom function is called.
[InfoPathEventHandler(MatchPath="/root/item", EventType=InfoPathEventType.OnAfterChange)]
public void item_OnAfterChange(DataDOMEvent e)
{
if (!e.IsUndoRedo && e.Source.nodeName != "item")
{
Calculate(e.Site.parentNode);
}
}
