IE 11 with grid

[gkushnerParticipant]

We are seeing very slow performance with the grid control at load time in Internet Explorer 11. We ran some performance traces and found that it is the IE implementation of offsetWidth that is the bottleneck.

JQWidget’s $.jqx.isEmpty is called 25,000 times during our typical page load.

Would it be possible to implement a more efficient (for IE11) empty check for your library or at least create an issue to check it?

Thank you.

Hi Gordon,

The demos on our side work ok with IE11, jQWidgets 3.4 and the performance is good from our point of view. We do not plan to make any special changes about this browser version. Also we are not aware what is $.jqx.isEmpty and we do not use such function in our code base.

We are currently using v3.2.2 and isEmpty is used extensively. I can email you a screenshot of the call stack if that will help.

We did update to 3.4 but had to rollback as there was a bug with selecting all rows. (I sent an email to support but never received a reply).

Please advise. Thank you.

Hi gkushner,

isEmpty is may be something on your side and we are not aware what it is. We do not have such method used in our code.

Is there an email I can send to your attention to point out the code and not violate your ToS? Thank you.

Hi gkushner,

The support e-mail is support@jqwidgets.com. I checked isEmpty. isEmpty is not used in our code. I would suggest you to check whether you have implemented such function and use it on your side.
