More important, however, are the next
two: the actual name of the element that was affected, and the operation performed, in this case, an Add
(an element was added).
Because Changing was placed on the root node, any change to the XML tree would have fired it.
To really see how this works, modify the code as follows (highlighted lines), then place a breakpoint on
the empXML.Changing line. This example doesn??™t add a new element; rather, it updates the value of an
existing element.
XElement empXML = new XElement("Employees",
new XElement("Employee",
new XAttribute("id", "1"),
new XAttribute("Dept", "0001"),
new XElement("Name", "Scott"),
new XElement("Address",
new XElement("Street", "555 Main St."),
new XElement("City", "Wellington"),
new XElement("State", "FL"),
new XElement("Zip", "33414")),
new XElement("Title", "All Things Techy"),
new XElement("HireDate", "02/05/2007"),
new XElement("Gender", "M")
)
);
empXML.Changing += new XObjectChangeEventHandler(delegate(object xsender,
XObjectChangeEventArgs cea)
{
listBox1.
