Detailed Description

Provides data for the XmlDocument::NodeChanged, XmlDocument::NodeChanging, XmlDocument::NodeInserted, XmlDocument::NodeInserting, XmlDocument::NodeRemoved and XmlDocument::NodeRemoving events.

Attention: Objects of this class should only be allocated using System::MakeObject() function. Never create instances of this type on stack or using operator new, as it will result in runtime errors and/or assertion faults. Always wrap this class into System::SmartPtr pointer and use this pointer to pass it to functions as argument.

Member Typedef Documentation

◆ Ptr

using System::Xml::XmlNodeChangedEventArgs::Ptr = SharedPtr<XmlNodeChangedEventArgs>

An alias for shared pointer to an instance of this class.

Constructor & Destructor Documentation

◆ XmlNodeChangedEventArgs()

System::Xml::XmlNodeChangedEventArgs::XmlNodeChangedEventArgs	(	const SharedPtr< XmlNode > &	node,
		const SharedPtr< XmlNode > &	oldParent,
		const SharedPtr< XmlNode > &	newParent,
		const String &	oldValue,
		const String &	newValue,
		XmlNodeChangedAction	action
	)

Initializes a new instance of the XmlNodeChangedEventArgs class.

Parameters

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.

Member Function Documentation

◆ get_Action()

XmlNodeChangedAction System::Xml::XmlNodeChangedEventArgs::get_Action ( )

Returns a value indicating what type of node change event is occurring.

Returns: One of the enumeration values that describes the node change event. The Action value does not differentiate between when the event occurred (before or after). You can create separate event handlers to handle both instances.

◆ get_NewParent()

SharedPtr<XmlNode> System::Xml::XmlNodeChangedEventArgs::get_NewParent ( )

Returns the value of the XmlNode::get_ParentNode after the operation completes.

Returns: The value of the 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.

◆ get_NewValue()

String System::Xml::XmlNodeChangedEventArgs::get_NewValue ( )

Returns the new value of the node.

Returns: The new value of the node. This method returns 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.

◆ get_Node()

SharedPtr<XmlNode> System::Xml::XmlNodeChangedEventArgs::get_Node ( )

Returns the XmlNode that is being added, removed or changed.

Returns: The XmlNode that is being added, removed or changed; this method never returns nullptr.

◆ get_OldParent()

SharedPtr<XmlNode> System::Xml::XmlNodeChangedEventArgs::get_OldParent ( )

Returns the value of the XmlNode::get_ParentNode before the operation began.

Returns: The value of the 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.

◆ get_OldValue()

String System::Xml::XmlNodeChangedEventArgs::get_OldValue ( )

Returns the original value of the node.

Returns: The original value of the node. This method returns 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.
