I found ExecCommand("PostBack") in the forums (not in the docs as far as I could see). This allows me to assume that if the command is "undefined" it is a javascript initiated "SaveAndExit".
HOWEVER, it would be neat if there was a more elegant solution, ie. allowing our own defined commands to be called using ExecCommand, or to set command name as follows:-
ExecCommand("SaveAndExit");
ExecCommand("Postback", "SaveAndExit");
Can this be done?
