Hello,

Could you provide with the demo link, where the problem can be reproduced?

Hello,

Below: calendar.asp, calendarTest4.asp.
calendarTest4.asp doesn’t reload when you go back to intervals you already visited (scheduler.config.prevent_cache = true)

calendar.asp:

      <style type="text/css" media="screen">

                overflow:hidden;
             }

Hello,
this is by design, dynamic loading does not reload dates that were already loaded. You can use this code snippet to enforce reloading:

scheduler.attachEvent("onBeforeViewChange", function (old_mode, old_date, mode, date) { if (old_mode != mode || +old_date != +date) scheduler.clearAll(); return true; });
