Examples
In the following example, the Operation property of the DataDOMEventObject object is used to check the type of action that is occurring to avoid multiple notifications for updates made to node values:
public void item_OnAfterChange(DataDOMEvent e)
{
if (!e.IsUndoRedo && e.<span class="label">Operation</span> == "Delete"
&& e.Site.nodeName == "item" &&
e.Source.nodeName == "item")
{
Calculate();
}
}
Remarks
The values that the Operation property returns include Insert, Update, and Delete.
