Good day!
I'm creating now a server-side export button.
I want ot modify the request, which is sent to server in preXhr.dt event.
E.g. I will clear the filters if I need to export the entire data without filters.
The basic concept:
1. click custom button, and set params for the export (e.g. all table OR current page), trigger fn.Draw().
2. On preXhr.dt check if any params are set, then we are exporting something, not just doing usual actions. If so, stop drawing.
Is it possible to do?

You could use
preDrawCallback(notpreXhr- it doesn't have a cancel option). But I wouldn't recommend it. Just don't request the draw if you don't want it to draw.Allan
Aha. Can you please tell me then, how do I get the same object as in
preXhrevent, which has all the details of the request being prepared?There is no option for that I'm afraid - sorry. As I say, the best thing to do is not to make the request in the first place.

Okay, thanks, allan!
