RDO provides built-in constants that you can use with methods, properties and events. These constants all begin with the letters "rd" and are documented with the event, method or property to which they apply. These constants are also used with RemoteData Control properties.
You can use the Object Browser to browse the list of built-in constants. From the View menu, choose Object Browser and select the appropriate library. Scroll the list in the Classes portion of the dialog to see the constants groups. To find a specific constant, use the search window to locate a specific group or constant.
