OK - I dunno how I missed that - thanks ! But. now I've updated the
code I cannot get the value that has been changed.
Code is below, but the Console.WriteLine() methods all return the value
that is loaded from the document. I would have expected the
NewParent.Value to return the value that it is to be changed to -
otherwise how do you access the value that it is being changed to.
Nothing on docs/google seem to indicate this.. just how to display on
NodeChanged.
//Create the event handlers.
doc.NodeChanging += new
XmlNodeChangedEventHandler(this.MyNodeChangedEvent);
..
// Handle the NodeChanged event.
public void MyNodeChangedEvent(Object src, XmlNodeChangedEventArgs
args)
{
Console.WriteLine("OrderID being updated with value " +
args.Node.Value);
Console.WriteLine("OrderID being updated with value " +
args.NewParent.Value);
Console.WriteLine("OrderID being updated with value " +
args.OldParent.Value);
Console.WriteLine(args.Action.ToString());
try
{
int newid = Convert.ToInt32(args.Node.Value);
Console.WriteLine(" with value {0}",
newid.ToString());
}
catch
{
throw new Exception(args.Node.Value + " must be an
integer value");
}
}

Steven,
The NodeChanged event is raised when the mutation of the node is
completed: by then, you cannot cancel the mutation by throwing an
exception in the event handler. To prevent the mutation, you should
handle the NodeChanging event instead: throwing an exception here,
prevents the node from actually be mutated.
HTH,
Stefan
