The event handler method receives the following arguments:
sender
A Calendar instance, which is the source of the event. This object will be passed to the handler function as the first argument.
args
An ItemModifiedEventArgs instance, which contains event data. This object will be passed to the handler function as the second argument.

The following example attaches a handler to the itemModified event of a calendar. In the handler method we check if the item was dragged to another location. If so, we save its previous start date.

var p = MindFusion.Scheduling; // attach a handler - when a calendar item is modified. calendar.itemModified.addEventListener(handleItemModified); function handleItemModified(sender, args) {     /* the args.action argument gives information about      * the action that was performed on the item */      if(args.action == p.ItemModifyAction.Drag)           {               var oldStartDate = args.oldItem.startTime;           }       }
