Slow Performance and Hiding Events

Thread ID:

Asked On March 4, 2019 02:29 PM UTC

I am using the calendar to show about 4-6 events a day and this is causing a noticeable delay in rendering when navigating from one month to another.

If I load a month's worth of data the delay is manageable noticeable but when navigating to a modal and back there is a substantial delay again.

I'm also trying to dynamically hide an event based on a value from an event object.

To make life easier I have attached a project with test code in it that mimic's what I'm trying to achieve.
