Event DataSourceChanged As EventHandler
The DataSourceChanged event is raised when the properties of a data-bound control or the underlying data has changed in some way that affects the data bindings between a data-bound control and its data. For example, the event is raised if a file name property, such as the DataFile property, is changed on a file-based data source control.
