Limiting calendar date selection

Vision 8.1.38

I've tried various search strings, and haven't been sucessful finding an answer. Perspective seems to have the feature on its calendar component but not vision?

I have start and end calendars for alarm journal history viewing. I don't want to allow an obscene span of date on the query. Ideally, start and end dates can be selected independently, but if one is 7 days +/- from the other, then limit the date.

I could do this with expression case/if on the journal start/end date itself, but then the calendar presentation would be out of synch with the actual data being queried.

Tldr: is there a way to limit the date selected in a calendar component?

You could do this on the query side, or with a change script on the component to force the date forward/back to the max.

You could add a propertyChange script to clamp the selected date to a max and min value.

if event.propertyName == 'date':
	if system.date.isBefore(event.newValue, event.source.minDate):
		event.source.date = event.source.minDate
	elif system.date.isAfter(event.newValue, event.source.maxDate):
		event.source.date = event.source.maxDate

I would use a property change script to enforce this by examining the delta between a new value and the other endpoint, and clipping the other endpoint if the span is too large.

Of course...not sure why I didnt think of that!

That worked well...I ended up using property change event to alter the opposing calander date to stay within range.

I am now trying to set default sort on the journal. I found this thread, but dont understand @MMaynard suggestion of where to put the script. I do not see any custom filter event or alarm summary control on a journal. Is that referencing an alarm status table instead?
