We have problem with selecting value from combo box and drop down list when there are more then 50 values. After selecting one value the focus on next input is slow. We saw that new Kendo version 2015.1.318 (core) have new property called data-index, we are on professional 2014.2.716 version. So can you please tell us how to speed up our project ?
If there is any question please ask.
Thank you in advanced.
