The OnDataPropertyChanged method is called when the DataSource or DataSourceID is changed any time after the page's PreRender event.

The following code 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. This code example is part of a larger example provided for the HierarchicalDataBoundControl class.
