Refreshing an event

Hello,
When I am pasting a copied event with drag and drop (custom functionality), the original event is “erased”.
If I refresh the scheduler, it appears again (it is stored in a DB).
How can I force-refresh scheduler after pasting an event ?

Thank you very much !

Hello,

Could you please provide with access to your application or show your code to help us understand the cause of the issue and have the opportunity to reproduce it?
How do you create a copy of event? Do you use dhtmlxscheduler_key_nav.js extension? docs.dhtmlx.com/scheduler/sampl … lugin.html

Hello,
Sorry, but I can’t provide you an access to the app.

I’m not, but I’m going to use it. Is it possible to add the ctrl + drag event in this extension ?
