Changed += new XObjectChangeEventHandler(
Chapter 3
[ 73 ]
delegate(object objSend, XObjectChangeEventArgs args)
{
XElement eleSend = (XElement)objSend;
MessageBox.Show(" XML Changed " + "\n " +
" Sender: " + eleSend.Name.LocalName +
" Change: " + args.ObjectChange.ToString(), "Changed Event");
}
);
Now create a new XML element which has the same number of elements and
attributes. We will use this new element to raise events on the original
XML element.
// Create a new XML element
XElement NewIcecream = new XElement("Icecream1",
new XElement("Name", "Vanilla Icecream"),
new XElement("Ingredients", "vanilla extract, guar gum,
cream, nonfat milk, sugar, locust bean gum, carrageenan,
annatto color..."),
new XElement("Cholesterol", "65mg")
);
Now add the new element to the existing ClassicIcecream element so the event
gets fired.
// Add the new element to the ClassicIcecreams so that
the events get fired
ClassicIcecreams.Add(NewIcecream);
At once, when we try to add new elements to the existing ClassicIcecream
element, the changing event fires just before the change happens.
