Namespace:  System.Web.UI
Assembly:  System.Web (in System.Web.dll)

event EventHandler^ DataSourceChanged {
	void add (EventHandler^ value);
	void remove (EventHandler^ value);

The DataSourceChanged event is raised when a change is made to the data source control's properties, such as changing the DataFile property of an XmlDataSource control, or changing the data in the underlying data storage, which happens when XML nodes are changed by an edit action performed by an XmlDataSource control.
