Hi, I've been trying to get my conditions to work for the past hour, only to realise that the Sample is actually kind of "cheating".
My tooltip template contains this amongst others:
${if(Location !== null)}(tags removed) ${Location} ${/if}
If Location is in fact null, "null" is printed on the tooltip.
https://ej2.syncfusion.com/aspnetcore/Schedule/Tooltip#/material
In your sample, you have a similar condition, checking for "City". If set City to null for any of the appointments there, e.g. for "Server Maintenance" (document.getElementById("schedule").ej2_instances[0].eventsData[0].City = null), then it's actually the same. It only works because all of the items have the City property set.
Could you please advise whether your sample is wrong or this is bug?
Thanks!
