Detect if an event has event handler

#1

Hi,

I need to bind the dropdown event to an event handler, but not from
beginning (in form's load or constructor), but little bit later, when
a background process completes.

Is there any way to detect if I already bound a handler to the event
(to not bind the handler several times)

Thank you

The easiest way is to just keep track of that in a boolean field.

I thought maybe it is a more elegant way

Thanks

Hi,

if you attach the same handler from the same object instance twice, it will
still be only called once.

Kind regards,

ind in files.

An event method can as well be used without an event.
