Hi Med. Ha, ok, I see it (maybe) now. But, if you only type "Return" without changing the content or "Esc", then you have not changed anything in the data. And then it is normal that ondataChange() is not triggered.
So, what you want is a new tmsedatasource.onKeyEnterorEsc() or a tmsedatasource.ondataChange() that checks if a key has been pressed, is that it? >.I can send you an example on handling filters using >tdbnavigator.datalink.execbutton(dbnbI). Yes, with pleasure + explain what the purpose is. Thanks.

I wanted to say that the event tmsedatasource.ondataChange is not fired when we type in just a return or escape in datacontrol.I can send you a sample about filter management using tdbnavigator.datalink.execbutton(dbnbI).

I've just uploaded it on my "hidden" mse web page for your disposition. Maybe you can make sense of it. Oh, and for its function: it just displays ANY key's codes on X11 in a couple of panes, giving names if known, and hex codes if not. And because it truely uses ALL keys, the only means to exit is the (really) BIG button named "Exit" in the bottom half... And, as that's been made for X11, I DON'T KNOW whether it's even compilable on Windows at all! -- (Weitergabe von Adressdaten, Telefonnummern u.ä. ohne Zustimmung nicht gestattet, ebenso Zusendung von Werbung oder ähnlichem) ----------------------------------------------------------- Mit freundlichen Grüßen, S.
