Canceling events

Hi,
I have code that looks like this:

function setupEventWrapp er(obj) {
old_ev_handler = obj.onsubmit;
obj.onsubmit = function () {
do_something();
if (old_ev_handler != undefined) {
old_ev_handler( );
}
if (event_cancelle d()) {
undo_something( );
}
}
}

it wraps the onsubmit handler (if any) within a new function which
do_something() and then calls the old event handler.

My problem is how can I detect if the event has been canceled by
old_ev_handler( ). AFAIK an event can be cancelled in three ways:

* returning false, easy to check for

* setting event.returnVal ue = false on IE, easy to check for

* calling event.preventDe fault() on DOM

How can I check if event.preventDe fault() has been called?


Thanks in advance

I answer myself, I've missed event.getPreven tDefault()

I selectively "disable" certain items in a ListBox. They appear gray and italicized. I want to make sure the user never selects these. Is there a way I can do this? For example, can I capture "SelectedItemChanged" and simply cancel it so that there will no subsequent call to DrawItem? Dom
