Hi Svetlin,
The feature I am talking about is ability to shift click the check boxes to select a range of rows. In the above example it doesn't allow it to shift click the check boxes. I had many discussions with the telerik support group (ticket id: 1172430) and specific discussions with Dimitter too. They have agreed that its a good feature and Dimitter himself created a github issue. https://github.com/telerik/kendo-angular/issues/2142
I just created this issue in the portal so that other users can also vote for it.
