NodeChanging Event

XmlDocument.NodeChanging Event

Occurs when the Value of a node belonging to this document is about to be changed.

Namespace: System.Xml
Assembly: System.Xml (in system.xml.dll)

public event XmlNodeChangedEventHandler NodeChanging
/** @event */
public void add_NodeChanging (XmlNodeChangedEventHandler value)

/** @event */
public void remove_NodeChanging (XmlNodeChangedEventHandler value)

JScript supports the use of events, but not the declaration of new ones.

This event allows the user to do extra checking and, if necessary, throw an exception to stop the operation. If an exception is thrown the XmlDocument returns to its original state. This event only applies to nodes that have a value.

All nodes created by this document, whether or not they have been inserted into the document, are included in this event.
