ButtonField.ValidateSupportsCallback Method
.NET Framework 3.0
Determines whether the controls that are contained in a ButtonField object support callbacks.
Namespace: System.Web.UI.WebControls
Assembly: System.Web (in system.web.dll)
Notes to Inheritors:
Classes that derive from the BoundField class can override the ValidateSupportsCallback method to indicate whether the controls that are contained by the field support callbacks. To indicate that callbacks are supported, implement the ValidateSupportsCallback 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.
Assembly: System.Web (in system.web.dll)
The ValidateSupportsCallback 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.
