A collection of custom buttons in navigator controls.
Properties that return NavigatorCustomButtons instances:
Navigator controls display a set of built-in buttons (which are used to scroll through the records, post and cancel data changes, insert and delete a record etc.), and they also allow you to display custom buttons that perform custom operations.
By default, custom buttons are displayed after the built-in buttons. To place a custom button at a specific position among the built-in and existing custom buttons, use the NavigatorCustomButton.Index property.
To respond to button clicks, handle the NavigatorBase.ButtonClick event.
