Hi.
Is it possible to trigger an event on .NET client (C#) from IRIS process? I'm using IRIS Native client to connect to IRIS server.

Regards,

This functionality is available when working with ActiveX (however, ActiveX is not recommended for use in new applications):

PS: in the Caché distribution there was even a special library DelphiCallback.dll for Delphi, an example of working with which is in my blog.

I've never worked with NET client but I suppose it works on request/response principle, so it is not possible to get async call from the database.

Depending on what you mean by a .NET client, using the .NET gateway might be a good place to start. https://docs.intersystems.com/irislatest/csp/docbook/DocBook.UI.Page.cls...
