Gets the exception (if any) that was raised during the delete operation.
Assembly: System.Web (in System.Web.dll)
Use the property to determine the exception (if any) that was raised during the delete operation. If no exceptions were raised, this property returns nullptr.
If an exception was raised and you decide to handle the exception in the event handler, be sure to set the ExceptionHandled property to true; otherwise, the exception is passed to the next method on the call stack for handling.
