) |
Initializes a new instance of the XmlNodeChangedEventArgs class.
node | The XmlNode that generated the event. |
oldParent | The old parent XmlNode of the XmlNode that generated the event. |
newParent | The new parent XmlNode of the XmlNode that generated the event. |
oldValue | The old value of the XmlNode that generated the event. |
newValue | The new value of the XmlNode that generated the event. |
action | The XmlNodeChangedAction. |
XmlNodeChangedAction System::Xml::XmlNodeChangedEventArgs::get_Action | ( | ) |
Returns a value indicating what type of node change event is occurring.
Action
value does not differentiate between when the event occurred (before or after). You can create separate event handlers to handle both instances. Returns the value of the XmlNode::get_ParentNode after the operation completes.
ParentNode
after the operation completes. This method returns nullptr
if the node is being removed. For attribute nodes, this method returns the XmlAttribute::get_OwnerElement value. String System::Xml::XmlNodeChangedEventArgs::get_NewValue | ( | ) |
Returns the new value of the node.
nullptr
if the node is neither an attribute nor a text node, or if the node is being removed. If called in a XmlDocument::NodeChanging event, get_NewValue
returns the value of the node if the change is successful. If called in a XmlDocument::NodeChanged event, get_NewValue
returns the current value of the node. Returns the value of the XmlNode::get_ParentNode before the operation began.
ParentNode
before the operation began. This method returns nullptr
if the node did not have a parent. For attribute nodes, this method returns the XmlAttribute::get_OwnerElement value. String System::Xml::XmlNodeChangedEventArgs::get_OldValue | ( | ) |
Returns the original value of the node.
nullptr
if the node is neither an attribute nor a text node, or if the node is being inserted. If called in a XmlDocument::NodeChanging event, get_OldValue
returns the current value of the node that will be replaced if the change is successful. If called in a XmlDocument::NodeChanged event, get_OldValue
returns the value of node prior to the change.
