greets Animal, et al!

this is a followup to viewtopic.php?t=31709

What is the same idea for checking double click and the right click context menu (prevent the creation of events in the past?)

I did look at beforeCreateMode. It is not clear what there should be as a return value, if a date is in the past. It's not a simple true / false, is it?

the beforeDragCreate() works fine. Just turning my attention to the double click and right click cases.

I updated that example to disable all things in the past.

very good, thanks!

there is one more: dont drag events to the past

const beforeDragMoveEnd = async ({ newEndDate }) => {
    if (newEndDate < new Date()) {
        const result = await MessageDialog.alert({
            title: "Alert",
            message: "Cannot move event to the past",
        });
        return false;
    }
};

I think we've got it now!

What we need is a preventable event that fires during a drag.

Take another look at the example. I've added a workaround which injects a handler into the Drag feature which fires an event.

I think we need to add this. Validation should be available during the drag, not just at the end.

cool, thanks

when you look at all the events we need to cover, in order to prevent the modification of the past, it does start to point back to a global variable such as historyIsReadOnly: true

however, that's an involved internals thing that you'd put on your roadmap, and I imagine it's sorta "medium" priority.. not a bug, but a "nice to have". We've figured out how to work with it for now . thanks!
