Dear,

Our users shouldn't be able to edit events which are in the past.

I've come up with the solution I added below which will give an alert. However I'm looking for a cleaner solution ... one that would make such events unclickable or would for example give a small stop sign OnHover. 

Could anyone point me in the right direction as to how I would locate these events with JQuery?

Thanks in advance.

Kind regards,
Yannick

function scheduler_OnEdit(e) {
        var now = new Date();

        if (e.event.TaskID > 0 && e.event.end < now) {
            alert("Events in the past cannot be changed.");
            e.preventDefault();
        }
    }
