Hello!

In our application, the combo boxes are working good every time an item is selected by mouse. But, when selecting items by touch (Chrome browser on Windows 10), if the combo uses filter and has less than 4 values, the selected item is sometimes seen as null. This happens sometimes also on this demo: http://demos.telerik.com/aspnet-mvc/combobox/index (but not every time).

Is this a bug, or is there a solution to solve the problem?

 

Thank you,

Iuliana Maria Candea

Hello Iuliana Maria,

I am not able to reproduce the described issue. Could you please isolate a sample dojo where the issue is always reproducible so we would be able to track its cause? Have you tested on multiple devices and what is the Chrome version?

Hi Joana, here is an example:

http://dojo.telerik.com/Iceji

When I filter by "MAC0" and have 6 items - works good

When I filter by "MAC1" - no item is selected, but the console had an item selected

When I filter by "MAC01" and have 2 items - no item is selected, and console writes null.

The Chrome version is 56.0.2924.87, and the device is a PC with touch, with windows 8 (but also happens on windows 10). Tested on Firefox and works fine. Also, when selecting by mouse, on same laptop or other laptop, works good. On tablet with Chrome 55 also works fine.

Hi Iuliana Maria,

Thank you for spending time preparing a sample and for the detailed report.

I tested the behavior in Chrome version which you have provided and latest. I didn't manage to reproduce an issue with no selection of an item, but indeed null value is given to the select method and it fires two times. This might lead to different behavior on different devices, so I logged an issue in our backlog. You could track its progress here: https://github.com/telerik/kendo-ui-core/issues/2902

I have updated your Telerik points for your report.
