Calendar Memory Leak?

The Calendar may leak memory if you put it inside an UpdatePanel and refresh the UpdatePanel too many times.

Two things could be done:

1. The Scheduler has an AutoRefresh feature which uses the internal callback mechanism to refresh the event set (much faster than using UpdatePanel which redraws the whole control). It seems this feature would be helpful for the Calendar as well.
2. The memory leak can be fixed be implementing the .dispose() interface. This is already done in the Scheduler too.

I will try to implement both as soon as possible. However, I can't promise any date at this moment.

Any news on when this issue will be addressed?

I have a page containing the navigator, calendar and month controls that refreshes itself at regular intervals and users are likely to leave it open all day. The DRIP tool shows memory leaks and continuously increasing memory use. This could end up being a showstopper for us.

DRIP also shows the memory leak for the Day Pilot demo page http://www.daypilot.org/demo/Calendar/

Thanks

As of build 6.2.2135 (see the sandbox), the Calendar shouldn't leak anything (on page unload, postback, partial postback, full and partial callback update), at least not anything detectable by drip.

By the way, drip is a bit old tool and I'm not sure if all the issues it reports are actual leaks (at least in IE8). Take this example:

var element = document.createElement("div");

If you don't add the element to the DOM, it is reported as a leak.

Anyway, I have addressed all the issues it reported and it seems that the memory consumption is no longer growing on repeated refresh.

The 6.2 release will include the autorefresh feature, just like the Scheduler.

Thanks, I believe the memory issues have been resolved. We've been testing with the new build and I've had no reports of problems.

Calendar V6.5 Autorefresh does NOT WORK.
I am using version 6.5 of the Calendar with the AutoRefresh option. The refresh STOPS working when I call amodal popup from the calender. This is provider example code for the calendar. So the autorefresh has fixed the memory leakage but does NOT continue to refresh the Calendar display. Any chance of a fix. I am going to use the timer with the update panel for my demo to new customer (even though it causes the memory leak). Hoping you will offer a fix soon so I can use the calendar in real world application.
