About the NavigationEvent class

Variables  Constructors  Properties  Methods  

Implements Serializable

This class is used to provide notification that the DataSet's cursor position has changed. This class is used by data-aware controls so that the UI can respond to the change in cursor location.

This event is sent out any time the current row position changes due to navigation operations like first, last, next, prior, and for editing operations like deleteRow and insertRow. Also note that post() can cause navigation since post() will navigate the newly posted row to its correct position in the DataSet. For sorted DataSets the posted position is determined by sort order. For non-sorted DataSets the posted position is at the end of the DataSet.
