public event VxiBackplaneTriggerEventHandler Trigger


This event can be a hardware or software trigger, depending on the interface and the current session settings.
Note: In some cases, callbacks and event handlers are executed in a different thread than the rest of the program. Therefore, you must take special care when accessing objects that have thread affinity, such as UI controls, from these callbacks and event handlers. For more information, refer to Events, Callbacks, and Thread Safety in Measurement Studio .NET Class Libraries.
