Determines whether the controls that are contained in a ButtonField object support callbacks.
Assembly: System.Web (in System.Web.dll)
The method is a helper method that is used to determine whether the controls that are contained in a ButtonField object support callbacks. This method is implemented as an empty method (a method that does not contain any code) to indicate that callbacks are supported.
The method is used primarily by control developers.
Classes that derive from the BoundField class can override the method to indicate whether the controls that are contained by the field support callbacks. To indicate that callbacks are supported, implement the 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.
