ListBox ScrollIntoView not working on touch screen devices
We are using List box item scroll into view to scroll to the item selected in the list box. However, the scroll is not working in the Chrome browser in a UHD touch screen laptop device.

Hi Kasim,

Happy New Year 2020!

I tried to reproduce the problem on a 4k display as well as on an Android phone with high resolution but without success.

On our side, the ScrollIntoView solution works as expected.

There is yet another experimental scroll method in the Chrome JS API specification - scrollIntoViewIfNeeded - you may want to try it out.

Hi Rumen,

Yes, I used a similar code in my application to scroll into view. It is working great with the non-touch screen devices. But on touch screen devices, it is always showing the first item in the list.

I debugged it using the browser developer tool in a couple of touch screen devices. The code is in fact executed without any exception but still, it does not scroll.

Hi Kasim,

Can you please explain in more detail your scenario? Do you use code similar to the one provided at https://www.telerik.com/forums/auto-scroll-radlistbox#l_-AyvDR1ECDy8O0ocOayQ?

You can also check the scrollIntoView of the item and of the the scrollIntoView of the HTML element of the item.

 

Can you record a short video which demonstrates the issue and send us a simple runnable project/aspx which isolates the problem?
