The OnDataPropertyChanged method is called when the DataSource, DataSourceID, or DataMember property value changes any time after the page's PreRender event has occurred.
The following code example shows a property that belongs to a derived data-bound control class. The example demonstrates how a data-bound control can call the OnDataPropertyChanged method if a property that identifies a data source is changed after the data-bound control is initialized.
