The DataNavigator is a control for navigating through the data object defined by its DataSource and DataMember properties. Please see the demos included in the XtraEditors to see how to use the DataNavigator control.
The ControlNavigator works only with a control which implements our INavigatableControl interface. It is a replacement for the grid's embedded navigator. The ControlNavigator can also work with unbound controls, e.g. the XtraTreeList.
