Hello Jim,

With the release of the last version of Kendo UI for jQuery, we've introduced a fix that resolves the case with the usage of the Scroller on devices with iOS 13. You can read about this fix in the release history notes of Kendo UI R3 SP1.

Please upgrade your application to Kendo UI ver. 2019.3.1023 and check if the issue still exists. 

Regards,
Petar

I just upgraded my iPhone X to 13.1.3 and have the same problem.  It had been reported by several of our customers.  It scrolls correctly on IOS 12.4 and works on iPad on 13.1.3.

Hi Martin,

do you have any updates regarding the issue? This is production issue causing all ios13 users to be unable to scroll and being unable to use our .

 

Our developers have some insights for the bug. IOS13 introduced support for Pointer Events API (https://developer.apple.com/documentation/safari_release_notes/safari_13_release_notes; https://developer.mozilla.org/en-US/docs/Web/API/PointerEvent).

Looks like Kendo JavaScript is in expecting this and setting touch-action none.

 

kendo.userevents.js

...
if (support.pointers || support.msPointers) {
    if (support.browser.version < 11) {
        var defaultAction = 'pinch-zoom double-tap-zoom';
        element.css('-ms-touch-action', options.touchAction && options.touchAction != 'none' ? defaultAction + ' ' + options.touchAction : defaultAction);
    } else {
        element.css('touch-action', options.touchAction || 'none');
    }
}

...

 

kendo.core.js

support.msPointers = !chrome && window.MSPointerEvent;
support.pointers = !chrome && !mozilla && window.PointerEvent;

 

 

Shall we expect from Kendo? How soon this could happen?

 

Thanks,

Andrew
