Remarks
This class represents ControlNavigator buttons via which a user can navigate through the records in a data source and perform operations on the data. The ControlNavigatorButtons class derives from the NavigatorButtonsBase class and inherits properties and methods common to all buttons used for the above mentioned above purposes. It introduces a set of properties allowing you to access a specific button. You can then customize its look and feel settings as your application needs dictate.
The following image illustrates the navigator’s buttons.
