Determines whether the controls contained in a CommandField object support callbacks.
Namespace: System.Web.UI.WebControls
Assembly: System.Web (in system.web.dll)
Notes to Inheritors:
Classes that derive from the CommandField class can override this method to indicate whether the controls contained by the field support callbacks. To indicate that callbacks are supported, implement this method as an empty method that does not throw an exception; otherwise, throw an exception with a useful message describing why callbacks are not supported.
