|
ActiveX
|
An ActiveX event raised for COM objects. The ActiveX type is not available for Rich Client tasks. If the event has built-in variables, they are created in the handler.
|
|
The ActiveX event is no longer supported.
|
|
|
.NET
|
Zoom from the Event field to open the .NET Event dialog box, where you can select a .NET variable and event. If the event has built-in variables, they are created as parameters in the handler with the relevant .NET type. You can also define an event handler without defining a variable. In such a case, you can write the object from which you want to select the event.
The .NET event handler’s behavior for Rich Client and Online is different:
-
In Rich Client, for non-control .NET objects – Since several tasks are running simultaneously, the behavior is non-standard and .NET events are raised in all the tasks, regardless of the propagation.
-
In Online – Since there is always one task tree, the behavior of non-control .NET objects is the same for .NET controls and is the same for any other event in Magic xpa.
