Browser zoom problem Posts

January 29, 2016 at 10:05 am Browser zoom problem #80921

Participant

I use virtual scrolling in my jqxgrid to display a lot of data. Further i use the sort functionality.
This works great. But if i change the browser zoom to a different value than 100% some strange effects appear.
It isn’t possible anymore to sort a column and display other data than the first page(virtual scrolling). Every time i slide down the jqxgrid-slider the new data are requested, but after that the grid switch automatically back to the first view.

If the browser zooming factor is 100% no problem occurs. (I tested this with firefox 44.0 and chrome 48.0).
Do you can help me?

Adjusted example: I only add sortable: true, to the grid settings

Hi schueppi,

You do not use jQwidget’s current version. gettheme.js is not part of our package from 1+ years. I suggest you to use the latest version of the software.

Hi schueppi,

I see. When the column is sorted, this happends indeed. Unfortunately, there’s no workaround. I will create a work item for a future update.

Hi, I’m facing the same issue. Has this been resolved in the later versions of jQWidgets?

If so, please send us a demo.

We are waiting for you!
