Prevent Dragging from Changing an Event’s Time and Resource

Prevent accidental drag and drop changes from modifying an event in a particular calendar source. This will prevent any dragged events from saving the changes to the event.

Easy Copy & Paste Install:

Simple copy and paste this into a new On Event Save event action:

//Revert changes if the event was dragged and dropped
if (event.beforeDrop) {
  action.callbacks.cancel();
}
else{
  action.callbacks.confirm();
}
		

Prevent Dragging from Changing an Event’s Time, while allowing Resource Changes

Use this verison of the app action if your users are primarily using the schedule views to assign items to resources and you don’t want them changing an item’s time when they do so. This mod will snap an event back to its original time if dragging the event accidentally includes a change to the event time.

Easy Copy & Paste Install:

Simple copy and paste this into a new On Before Save event action:

//Before Event Save
function noTimeChange() {
    //drag and drop or popover edit?
    if(event.beforeDrop) {
      if(event.allDay!==event.beforeDrop.allDay || 
        !event.start.isSame(event.beforeDrop.start) || 
        !event.end.isSame(event.beforeDrop.end)) {
        event.allDay = event.beforeDrop.allDay;
        event.start = event.beforeDrop.start.clone();
        event.end = event.beforeDrop.end.clone();
      }
  }
}
noTimeChange();
